JP 2009-156783 A

Generally, infrastructure such as water pipes are laid beneath roads. While the vehicle position recognition device can obtain construction information about roads, it cannot, for example, detect the impact of construction on infrastructure.

Therefore, it is desirable to detect the impact of construction work on infrastructure.

An infrastructure impact calculation device according to one aspect of the present disclosure includes a calculation unit that calculates an infrastructure impact, which is the degree of impact that construction work will have on road infrastructure, based on the distance between a construction object, which is one or more objects related to the construction work, and road infrastructure, which is infrastructure laid below, above, or around the road.

In this regard, the infrastructure impact level, which is the degree of impact of construction work on road infrastructure, can be calculated, making it possible to detect the impact of construction work on infrastructure.

According to one aspect of the present disclosure, it is possible to detect the impact of construction work on infrastructure.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. Note that in the description of the drawings, identical elements will be given the same reference numerals, and duplicate explanations will be omitted. Furthermore, the embodiments of the present disclosure described below are specific examples of the present invention, and unless otherwise specified, the present invention is not limited to these embodiments.

Figure 1 is a diagram showing an example of the system configuration of an infrastructure impact calculation system 4 including an infrastructure impact calculation device 1 according to an embodiment. As shown in Figure 1, the infrastructure impact calculation system 4 includes an infrastructure impact calculation device 1, one or more vehicles 2 (multiple vehicles 2 will be collectively referred to as "vehicles 2" as appropriate), and one or more external devices 3 (multiple external devices 3 will be collectively referred to as "external devices 3" as appropriate). The infrastructure impact calculation device 1 and the vehicles 2 are communicatively connected to each other via a network such as a mobile communications network, and can send and receive information between them. The infrastructure impact calculation device 1 and the external devices 3 are communicatively connected to each other via a network such as the Internet, and can send and receive information between them.

The infrastructure impact calculation device 1 is a server device that calculates the infrastructure impact, which is the degree of impact of construction work on road infrastructure. In this embodiment, the construction work is assumed to be road construction, but is not limited to this and may be general civil engineering or construction work. Road infrastructure refers to infrastructure laid under, above, or around (nearby, nearby, nearby, around, surrounding, beside, alongside, within a specified distance from) a road. Road infrastructure includes, for example, water pipes (water pipes, sewer pipes), gas pipes, electric wires, or communication lines buried under the road, electric wires or communication lines strung on utility poles above the road, or water pipes, gas pipes, electric wires, communication lines, or railroad tracks laid to the side or beside the road. The impact level is the degree of impact. The impact level may be expressed, for example, as an integer between "0" and "100," with values closer to "0" indicating less impact and values closer to "100" indicating greater impact. The impact may also be expressed as a probability, a real number, or a discrete value such as "large," "medium," or "small," but is not limited to these. Details of the infrastructure impact calculation device 1 will be described later.

Vehicle 2 is a typical wheeled vehicle. In this embodiment, it is assumed to be a car traveling on a road owned by the user of infrastructure impact calculation device 1, but this is not limited to this. Vehicle 2 is equipped with a dashcam D, which is a drive recorder. Dashcam D is a video camera (imaging device) attached to the windshield or dashboard of vehicle 2. Dashcam D captures images of the road outside the vehicle and outputs them as road images. In this embodiment, the term "image" may be replaced with "video," "video," or "moving image," as appropriate. Vehicle 2 transmits road images (images of the road) captured by dashcam D to infrastructure impact calculation device 1 via a network at any or predetermined times.

The dashcam D may be equipped with a GPS (Global Positioning System). The dashcam D may use the GPS to output imaging position information (latitude, longitude, etc.) relating to the location where the road image was captured (the location of the dashcam D). The vehicle 2 may transmit the road image captured by the dashcam D and the imaging position information (output by the dashcam D) relating to the location where the road image was captured to the infrastructure impact calculation device 1 via the network at any or predetermined timing.

The external device 3 is an external server device (with respect to the infrastructure impact calculation device 1). The external device 3 pre-stores various information used in the processing of the infrastructure impact calculation device 1 and transmits (provides) it to the infrastructure impact calculation device 1 via a network. The external device 3 may transmit road infrastructure information related to road infrastructure to the infrastructure impact calculation device 1. The road infrastructure information may include at least one of the (pre-set) location (latitude, longitude, etc.) of the road infrastructure, its type, depth (under the road), height (above the road), and years of installation. The road infrastructure information makes it possible to understand the buried (installed) status of the road infrastructure. The external device 3 may transmit construction information related to construction work to the infrastructure impact calculation device 1. The construction information may include at least one of information related to construction work that has been notified in advance to the company or local government that owns the infrastructure (notified construction work), the construction location (latitude, longitude, etc.), waiting locations for construction personnel (latitude, longitude, etc.), and weights according to the type of construction object (described below).

If there are multiple external devices 3, each external device 3 may store different types of information. The external devices 3 may be incorporated into the infrastructure impact calculation device 1. In other words, the infrastructure impact calculation device 1 (the storage unit 10 described below) may store the various types of information described above in advance.

Figure 2 is a diagram showing an example of the functional configuration of the infrastructure impact calculation device 1 according to the embodiment. As shown in Figure 2, the infrastructure impact calculation device 1 includes a storage unit 10, an acquisition unit 11 (acquisition unit), an extraction unit 12 (extraction unit), a calculation unit 13 (calculation unit), and a display unit 14 (display unit).

It is assumed that each functional block of the infrastructure impact calculation device 1 functions within the infrastructure impact calculation device 1, but this is not limited to this. For example, some of the functional blocks of the infrastructure impact calculation device 1 may function within a computer device different from the infrastructure impact calculation device 1, and connected to the infrastructure impact calculation device 1 via a network, while appropriately sending and receiving information with the infrastructure impact calculation device 1. Furthermore, some functional blocks of the infrastructure impact calculation device 1 may be absent, multiple functional blocks may be integrated into a single functional block, or one functional block may be broken down into multiple functional blocks.

The following describes each function of the infrastructure impact calculation device 1 shown in Figure 2.

The storage unit 10 stores any information used in calculations by the infrastructure impact calculation device 1, as well as the results of calculations by the infrastructure impact calculation device 1. The information stored by the storage unit 10 may be referenced as appropriate by each function of the infrastructure impact calculation device 1.

The acquisition unit 11 acquires road images captured on a road. The acquisition unit 11 may also acquire road images captured by a dashcam D (in the vehicle 2). The acquisition unit 11 may further acquire imaging position information relating to the position where the road image was captured.

Specifically, the acquisition unit 11 acquires, via a network, at least one of a road image captured by the dashcam D of the vehicle 2 and transmitted from the vehicle 2, and imaging position information (output by the dashcam D) relating to the position where the road image was captured. If there are multiple vehicles 2, the acquisition unit 11 may acquire at least one of a road image and imaging position information from each vehicle 2. The acquisition unit 11 may acquire at least one of a road image and imaging position information stored by the storage unit 10 (rather than from the vehicle 2). The acquisition unit 11 may acquire at least one of a road image and imaging position information from another device (rather than from the vehicle 2) via a network or the like.

The acquisition unit 11 may acquire various types of information from the external device 3 via the network. For example, the acquisition unit 11 may acquire at least one of road infrastructure information and construction information from the external device 3. If there are multiple external devices 3, the acquisition unit 11 may acquire at least one of road infrastructure information and construction information from one or more of the external devices 3. The acquisition unit 11 may acquire at least one of road infrastructure information and construction information stored by the storage unit 10 (rather than from the external device 3).

The acquisition unit 11 may output the acquired information (road images, imaging location information, various information, road infrastructure information, construction information, etc.) to the extraction unit 12, calculation unit 13, or display unit 14, or may store it in the storage unit 10.

The extraction unit 12 extracts (recognizes) construction objects included in the road image acquired by the acquisition unit 11. A construction object is one or more objects (targets) related to construction work (multiple construction objects will be collectively referred to as "construction objects" as appropriate). An object may be an object or a person. For example, construction objects may be cones (color cones (registered trademark)), cone bars, barricades, fences, arrow signs, (construction) signs, other construction items, excavators, cranes, other (construction) special vehicles, construction sites, waiting areas for construction workers, people wearing (construction) helmets, other construction workers, etc.

Specifically, the extraction unit 12 acquires road images output from the acquisition unit 11 or road images stored by the storage unit 10, and extracts construction objects from the acquired road images using existing image object extraction technology. For example, construction objects contained in road images may be extracted using a trained model that has been machine-learned in advance using images of construction objects. Alternatively, for example, after extracting arbitrary objects from road images using an open software library such as OpenCV, only the construction objects may be extracted using pattern matching technology or the like.

The extraction unit 12 may further extract relative position information regarding the relative position between the position where the road image was captured and the position of each construction object, based on the imaging position information acquired by the acquisition unit 11. Specifically, the extraction unit 12 acquires the road image and imaging position information output from the acquisition unit 11, or the road image and imaging position information stored by the storage unit 10, and extracts relative position information for the acquired road image based on the acquired imaging position information and the construction objects extracted by the extraction unit 12, using existing technology for extracting the relative position of objects included in the image. For example, the extraction unit 12 extracts (measures) the relative position between the position of the vehicle 2 (or the dashcam D) and the position of each construction object using technology such as monocular depth estimation, SLAM (Simultaneous Location and Mapping), or SfM (Structure from Motion).

The extraction unit 12 may output the extraction results to the calculation unit 13 or the display unit 14, or may store them in the storage unit 10. The extraction results may be a set of pairs of information identifying construction objects, such as "[cone, (5.3 m, -1.2 m)], [barricade, (-4.7 m, 3.8 m)], ...", and relative position information, which is the relative coordinates between the construction object and the position where the road image was captured.

The calculation unit 13 calculates the infrastructure impact degree, which is the degree of impact of the construction work on the road infrastructure, based on the distance between the construction object and the road infrastructure. The calculation unit 13 may calculate the infrastructure impact degree based on the distance between the construction object extracted by the extraction unit 12 and the road infrastructure. The calculation unit 13 may calculate the distance between the construction object and the road infrastructure based on the imaging position information acquired by the acquisition unit 11, the relative position information extracted by the extraction unit 12, and information regarding the predetermined position of the road infrastructure (included in the road infrastructure information acquired by the acquisition unit 11 from the external device 3).

3 is a diagram showing an example of distances between construction objects and road infrastructure. The diagram includes a water pipe W, which is one of the road infrastructure, cones C1, C2, and C3, which are construction objects, a barricade B, which is another construction object, and an arrow A, which is another construction object. The (shortest) distance between (the center line of) the water pipe W and the cone C1 is indicated by distance d _C1 , the distance between the water pipe W and the barricade B is indicated by distance d _B , the distance between the water pipe W and the cone C2 is indicated by distance d _C2 , the distance between the water pipe W and the cone C3 is indicated by distance d _C3 , and the distance between the water pipe W and the arrow A is indicated by distance d _A.

The calculation unit 13 performs coordinate calculations etc. based on the extraction results output by the extraction unit 12 or the extraction results stored by the storage unit 10, the imaging position information output by the acquisition unit 11 or the imaging position information stored by the storage unit 10, and the road infrastructure information (or information regarding the location of the road infrastructure) output by the acquisition unit 11 or the road infrastructure information (or information regarding the location of the road infrastructure) stored by the storage unit 10, and calculates the above-mentioned distances d _C1 , distance d _B , distance d _C2 , distance d _C3 and distance d _A.

The calculation unit 13 may calculate the infrastructure impact score based on the distance d _j (j is the index value of the construction object) between the construction object and the road infrastructure using the following formula (1).
score=Σ(1/d _j )...(1)

That is, the more construction objects there are and the shorter (smaller) the distance _dj between the construction objects and the road infrastructure, the greater the infrastructure impact.

The calculation unit 13 may also calculate the infrastructure impact degree based on the type of each construction object. More specifically, the calculation unit 13 may calculate the infrastructure impact degree by weighting the distance between the construction object and the road infrastructure according to the type of the construction object. Figure 4 is an example table of weights according to the type of construction object. As shown in Figure 4, special vehicles such as excavators and cranes are weighted higher than construction items such as signs and cones. Construction items such as signs and cones are not dangerous to road infrastructure, so their weights can be set relatively low. On the other hand, special vehicles such as excavators and cranes may damage road infrastructure, so their weights can be set relatively high. The weights according to the type of construction object may be acquired from the storage unit 10 where they are stored in advance, or may be acquired from construction information acquired by the acquisition unit 11 from the external device 3.

The calculation unit 13 may calculate the infrastructure impact score using the following formula (2), further based on a weight _wi (i is an index value of the type) according to the type of each construction object (in addition to formula (1)).
score=ΣΣ( _wi /d _i,j )...(2)

In other words, the higher the weight for the type of construction object, the greater the impact on infrastructure.

The calculation unit 13 may calculate the infrastructure impact level based on a distance (between a construction object and road infrastructure) that meets a predetermined criterion. More specifically, the calculation unit 13 may calculate the infrastructure impact level based on a distance that is less than (or equal to or less than) a predetermined threshold. For example, if the distance between a construction object and road infrastructure is greater than or equal to the threshold δ, the calculation unit 13 ignores (sets to zero) the infrastructure impact level for that construction object. This reduces the amount of calculation when construction objects span a wide area.

The calculation unit 13 may calculate the infrastructure impact level based further on the depth or height of the road infrastructure. For example, the calculation unit 13 may set weights according to the type of construction object described above according to the depth of the road infrastructure. Figure 5 is an example table of construction object weights according to the (buried) depth of the road infrastructure. As shown in Figure 5, the shallower the road infrastructure, the greater the weight. For example, the example table shown in Figure 5 shows that if the road infrastructure is shallow and there is a bulldozer as a construction object, the weight is greater, i.e., the infrastructure impact level is greater. That is, the calculation unit 13 uses the inverse of the depth of the road infrastructure as the weight. While Figure 5 is an example of the depth of the road infrastructure, the same applies to the height of the road infrastructure. The weight can be set to be greater the lower the road infrastructure. That is, the calculation unit 13 uses the inverse of the height of the road infrastructure as the weight. The depth or height of the road infrastructure may be acquired from the storage unit 10 where it is pre-stored, or may be acquired from road infrastructure information acquired by the acquisition unit 11 from the external device 3.

The calculation unit 13 may calculate the infrastructure impact degree further based on the number of years since the road infrastructure was laid. The calculation unit 13 may calculate the infrastructure impact degree score further based on the number of years since the road infrastructure was laid (relative to equation (2)) using the following equation (3).
score=Y/10*ΣΣ( _wi /d _i,j )...(3)

In other words, the older the road infrastructure is, the greater the impact on the infrastructure. This is because the older the road infrastructure, the more likely it is to deteriorate and be damaged. Note that the division by "10" in equation (3) is for the purpose of aligning the other values.

The calculation unit 13 may calculate the infrastructure impact degree further based on the distance between the road infrastructure or the construction site and the construction workers or the waiting location of the construction workers. FIG. 6 is a diagram showing an example of the distance between the road infrastructure and the construction workers. In FIG. 6, a water pipe W, which is road infrastructure, and a construction worker P are included. The (shortest) distance between (the center line of) the water pipe W and the construction worker P is indicated by distance _dP . The calculation unit 13 may calculate the infrastructure impact degree score further based on the distance _dP (with respect to equation (2)) using the following equation (4):
score=d _P /10*ΣΣ(w _i /d _i,j )...(4)

In other words, the greater the distance (length) between the road infrastructure and the construction workers, the greater the impact on the infrastructure. Note that the division by "10" in equation (4) is intended to make the other values align.

In the above description of Figure 6, the road infrastructure may be replaced with a construction site, and construction personnel P may be replaced with a waiting location for construction personnel. For example, the calculation unit 13 calculates the infrastructure impact level according to the distance between the nearby road infrastructure where construction is taking place and the waiting location for construction personnel, because the longer it takes for emergency response personnel to arrive at the site, the longer it will take. The construction site and the waiting location for construction personnel may be obtained from the storage unit 10 where they are stored in advance, or may be obtained from construction information obtained by the acquisition unit 11 from the external device 3.

The calculation unit 13 may output the calculated infrastructure impact to the display unit 14, store it in the storage unit 10, display it to a user of the infrastructure impact calculation device 1 via the output device 1006 described below, or output it to another device via a network, etc.

The display unit 14 displays on a map based on the infrastructure impact calculated by the calculation unit 13. The display unit 14 may also display construction objects and road infrastructure on the map.

Figure 7 is a diagram showing an example of a display based on the infrastructure impact level on a map. Figure 7 is an example screen displayed by the display unit 14. The upper left of the example screen is a road image acquired from the vehicle 2. The road images may be displayed as a video arranged in chronological order. The right of the example screen is a map of the vicinity of the position indicated by the road image in the upper left of the example screen. The display unit 14 displays information related to road infrastructure superimposed on the map based on the road infrastructure information stored by the storage unit 10 or the road infrastructure information output by the acquisition unit 11. In Figure 7, a dotted line indicating a water pipe W is displayed superimposed on the map.

The display unit 14 displays information about the construction object superimposed on a map based on the imaging location information output by the acquisition unit 11 or the imaging location information stored by the storage unit 10, and the extraction results stored by the storage unit 10 or the extraction results output by the extraction unit 12. In FIG. 7, a circle indicating the presence of construction object O is displayed superimposed on the map. The display unit 14 may also display information on the map based on at least one of the type of construction object, the number of detected construction objects, or the area of the construction object. For example, the display unit 14 may change the color of the circle depending on the type of construction object, display the circle larger in proportion to the number of detected construction objects, display the circle larger in accordance with the area ratio of the construction objects, or display a heat map corresponding to the area ratio of the construction objects as a grid on the map.

The bottom left of Figure 7 shows various information displayed by the display unit 14. The example screen shown in Figure 7 displays the number of construction objects extracted by the extraction unit 12 (for the road image in the upper left of the example screen), the infrastructure impact level output by the calculation unit 13, and information indicating whether the construction work (near the position indicated by the road image in the upper left of the example screen) is a notified construction work. The information indicating whether the construction work is a notified construction work is displayed by the display unit 14 based on construction information acquired by the acquisition unit 11 from the external device 3.

Next, an example of the processing (infrastructure impact calculation method) executed by the infrastructure impact calculation system 4 will be described with reference to Figure 8. Figure 8 is a sequence diagram showing an example of the processing executed by the infrastructure impact calculation system 4.

First, vehicle 2 captures a road image using dashcam D (step S1). Next, vehicle 2 transmits the road image and capture location information to infrastructure impact calculation device 1 (step S2). Next, infrastructure impact calculation device 1 requests external information from external device 3 (step S3). Next, external device 3 transmits the external information in response to S3 (step S4). Next, extraction unit 12 of infrastructure impact calculation device 1 extracts construction objects based on the information received in S2 and S4 (step S5, extraction step). Next, calculation unit 13 of infrastructure impact calculation device 1 calculates infrastructure impact based on the information received in S2 and S4 and the extraction results of S5 (step S6, calculation step). Next, display unit 14 of infrastructure impact calculation device 1 displays an infrastructure impact based on the information received in S2 and S4, the extraction results of S5, and the calculation results of S6 (step S7, display step).

Note that the timing of S3 and S4 is not limited to after S2 and before S5, but may be any timing. For example, they may be executed whenever external information becomes necessary in the processing of the infrastructure impact calculation device 1.

Next, we will explain the effects of the infrastructure impact calculation device 1 according to the embodiment.

According to the infrastructure impact calculation device 1, the calculation unit 13 calculates the infrastructure impact, which is the degree of impact of construction work on road infrastructure, based on the distance between a construction object, which is one or more objects related to the construction work, and the road infrastructure, which is the infrastructure laid below, above, or around the road. With this configuration, the infrastructure impact, which is the degree of impact of construction work on road infrastructure, is calculated, making it possible to detect the impact of construction work on infrastructure. It is also possible to detect the degree of impact of construction work on infrastructure.

Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact further based on the type of each construction object. This configuration makes it possible to calculate a more accurate infrastructure impact that is further tailored to the type of each construction object.

Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact based on distances that meet predetermined criteria. With this configuration, for example, the amount of calculation can be reduced by omitting calculations for distances that do not meet the predetermined criteria.

Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact further based on the depth or height of the road infrastructure. This configuration makes it possible to calculate a more accurate infrastructure impact that is further tailored to the depth or height of the road infrastructure.

Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact based further on the number of years since the road infrastructure was laid. This configuration makes it possible to calculate a more accurate infrastructure impact that is further in line with the number of years since the road infrastructure was laid.

Furthermore, with the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact based on the distance between the road infrastructure or construction site and the construction personnel or their waiting location. This configuration makes it possible to calculate a more accurate infrastructure impact that is further tailored to, for example, the arrival time of emergency construction personnel at the site.

Furthermore, according to the infrastructure impact calculation device 1, the acquisition unit 11 acquires road images captured on a road, the extraction unit 12 extracts construction objects included in the road images acquired by the acquisition unit 11, and the calculation unit 13 calculates the infrastructure impact based on the distance between the construction objects extracted by the extraction unit 12 and the road infrastructure. This configuration makes it easier to calculate the infrastructure impact based on the captured road images.

Furthermore, according to the infrastructure impact calculation device 1, the acquisition unit 11 may acquire road images captured by a dashcam D. This configuration allows the use of existing dashcams D (and vehicles 2), thereby reducing the investment costs involved in building the infrastructure impact calculation system 4.

Furthermore, according to the infrastructure impact calculation device 1, the acquisition unit 11 further acquires imaging position information relating to the position where the road image was captured, the extraction unit 12 further extracts relative position information relating to the relative position between the position where the road image was captured and the position of each construction object based on the imaging position information acquired by the acquisition unit 11, and the calculation unit 13 may calculate the distance between the construction object and the road infrastructure based on the imaging position information acquired by the acquisition unit 11, the relative position information extracted by the extraction unit 12, and information relating to the position of the preset road infrastructure. This configuration enables more accurate distance calculation based on position, thereby enabling more accurate calculation of infrastructure impact.

Furthermore, according to the infrastructure impact calculation device 1, the display unit 14 may display on a map based on the infrastructure impact calculated by the calculation unit 13. With this configuration, the user of the infrastructure impact calculation device 1 can easily check the display based on the infrastructure impact on the map.

The infrastructure impact calculation device 1 is also a system that recognizes objects from video captured by a dashcam D and visualizes them on a map. More specifically, the infrastructure impact calculation device 1 is a system that recognizes target objects from video captured by a dashcam D and, based on the location information of the dashcam D, represents and visualizes the number and type of recognized objects on a map.

Previously, road construction and other work required advance notification to the companies that own the infrastructure or local governments to avoid damaging buried infrastructure. However, some construction work did not require notification, and the companies that own the infrastructure or local governments would patrol the area to identify the problem and issue instructions on-site. However, this required a lot of human resources.

The infrastructure impact calculation device 1 detects objects using video captured by a dashcam D, and visualizes the results on a map using the dashcam D's location information. By comparing this information with the installation status of various buried infrastructure and notified construction work, patrols become unnecessary.

The extraction unit 12 of the infrastructure impact calculation device 1 can also be considered as an object recognition engine, and the calculation unit 13 and display unit 14 of the infrastructure impact calculation device 1 can also be considered as a visualization system.

The infrastructure impact calculation device 1 may calculate a score according to the detection type (of the construction object) and calculate and visualize the urgency (infrastructure impact) in conjunction with the laying status of the buried infrastructure (road infrastructure).

The block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of hardware and/or software. Furthermore, there are no particular limitations on how each functional block is realized. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are connected directly or indirectly (for example, using a wired or wireless connection) and these multiple devices. A functional block may also be realized by combining software with the single device or multiple devices.

Functions include, but are not limited to, judgment, determination, assessment, calculation, computation, processing, derivation, investigation, search, confirmation, reception, transmission, output, access, resolution, selection, election, establishment, comparison, assumption, expectation, regard, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assignment. For example, a functional block (component) that performs transmission functions is called a transmitting unit or transmitter. As mentioned above, there are no particular limitations on how these functions are implemented.

For example, the infrastructure impact calculation device 1 according to an embodiment of the present disclosure may function as a computer that performs processing of the infrastructure impact calculation method of the present disclosure. Figure 9 is a diagram showing an example of the hardware configuration of the infrastructure impact calculation device 1 according to an embodiment of the present disclosure. The above-mentioned infrastructure impact calculation device 1 may be physically configured as a computer device including a processor 1001, memory 1002, storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

In the following description, the term "device" can be interpreted as a circuit, device, unit, etc. The hardware configuration of the infrastructure impact calculation device 1 may be configured to include one or more of the devices shown in the figure, or may be configured to exclude some of the devices.

Each function of the infrastructure impact calculation device 1 is realized by loading specific software (programs) onto hardware such as the processor 1001 and memory 1002, causing the processor 1001 to perform calculations, control communications via the communication device 1004, and control at least one of reading and writing data from and to the memory 1002 and storage 1003.

The processor 1001, for example, runs an operating system to control the entire computer. The processor 1001 may be configured as a central processing unit (CPU) that includes an interface with peripheral devices, a control unit, an arithmetic unit, a register, etc. For example, the above-mentioned acquisition unit 11, extraction unit 12, calculation unit 13, and display unit 14 may be realized by the processor 1001.

The processor 1001 also reads programs (program code), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002 and executes various processes in accordance with these. The programs used are those that cause a computer to execute at least some of the operations described in the above-described embodiments. For example, the acquisition unit 11, extraction unit 12, calculation unit 13, and display unit 14 may be implemented by a control program stored in the memory 1002 and running on the processor 1001, and similar implementations may be used for other functional blocks. While the above-described various processes have been described as being executed by a single processor 1001, they may also be executed simultaneously or sequentially by two or more processors 1001.

Software, instructions, information, etc. may also be transmitted and received via a transmission medium. For example, if software is transmitted from a website, server, or other remote source using wired technologies (such as coaxial cable, fiber optic cable, twisted pair, or Digital Subscriber Line (DSL)) and/or wireless technologies (such as infrared or microwave), these wired and/or wireless technologies are included within the definition of transmission media.

The information, signals, etc. described in this disclosure may be represented using any of a variety of different technologies. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

Note that terms explained in this disclosure and terms necessary for understanding this disclosure may be replaced with terms having the same or similar meanings.

As used in this disclosure, the terms "system" and "network" are used interchangeably.

Furthermore, the information, parameters, etc. described in this disclosure may be expressed using absolute values, relative values from a predetermined value, or other corresponding information.

The names used for the parameters described above are not limiting in any way. Furthermore, the mathematical formulas and the like using these parameters may differ from those explicitly disclosed in this disclosure.

As used in this disclosure, the terms "determining" and "determining" may encompass a wide variety of actions. "Determining" and "determining" may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, inquiring (e.g., searching a table, database, or other data structure), and ascertaining, all of which are considered to be "judging" or "determining." "Determining" and "determining" may also include receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, and accessing (e.g., accessing data in memory), all of which are considered to be "judging" or "determining." "Determining" and "determining" may also include resolving, selecting, choosing, establishing, comparing, and other actions, all of which are considered to be "judging" or "determining." In other words, "judgment" and "decision" can include regarding some action as having been "judged" or "decided." Furthermore, "judgment (decision)" can also be interpreted as "assuming," "expecting," "considering," etc.

The terms "connected," "coupled," or any variation thereof, refer to any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, "connected" may be read as "access." As used in this disclosure, two elements may be considered to be "connected" or "coupled" to each other using one or more wires, cables, and/or printed electrical connections, as well as electromagnetic energy having wavelengths in the radio frequency range, microwave range, and optical (both visible and invisible) range, as some non-limiting and non-exhaustive examples.

As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Furthermore, when the term "or" is used in this disclosure, it is not intended to be an exclusive or.

In this disclosure, where articles are added by translation, such as a, an, and the in English, this disclosure may include the noun following these articles being plural.

In this disclosure, the term "A and B are different" may mean "A and B are different from each other." It should be noted that the term may also mean "A and B are each different from C." Terms such as "separate" and "combined" may also be interpreted in the same way as "different."
