Description

The present invention relates to a route display device, a route display method, and a route display program.

Conventionally, many navigation technologies combining location information and map information have been proposed. In recent years, with the widespread use of mobile devices equipped with cameras such as smartphones, navigation technologies using Augmented Reality (AR) that further combine images captured by a camera have been proposed. One example of this navigation technology using Augmented Reality is a mobile device that displays an arrow image on an image generated by a camera, indicating the direction to follow to an evacuation route to evacuate outside a building, thereby allowing a user to intuitively understand the direction in which to evacuate (see Patent Document 1).

JP 2014-142758 A

However, with the mobile terminal disclosed in Patent Document 1, it is difficult to know whether to proceed in a straight line from the current location to the exterior of the building, which is the destination, or whether to proceed while turning corners.

The present invention was made in consideration of the above problems, and aims to make it easier to know whether to proceed from the current location to the destination in a straight line or by turning corners.

In order to solve the above problems, the route display device of the present invention comprises:
A communication means capable of communicating with access points provided at each spot in the facility;
An imaging means;
A route display device comprising:
a positioning means for measuring a current position of the device itself based on the position information of each of the spots and a communication status with an access point provided at each of the spots;
a route creation means for creating a route from the current position measured by the positioning means as an initial position to a destination;
a route display control means for displaying the route, which is aligned with the orientation of a space in the facility photographed by the imaging means, superimposed on an image of the space;
Equipped with
The route creation means
if an angle between a reference line segment connecting a predetermined spot closest to the initial position and a spot closest to the initial position in a direction from the predetermined spot toward the destination, and a line segment connecting the initial position to the destination in a straight line, exceeds a predetermined angle, a spot passing route is created as the route from the spot closest to the initial position to the destination via each spot,
If an angle between the reference line segment and a line segment connecting the initial position to the destination in a straight line is within a predetermined angle, a direct route going in a straight line from the initial position to the destination is generated as the route.
It is characterized by the following.

With this configuration, either a route via a spot or a direct route is created depending on the destination, and the route is displayed in accordance with the orientation of the space within the facility captured by the imaging means, superimposed on an image of the space, making it easier for the user to know whether to proceed in a straight line from the current position to the destination or to proceed while turning corners.

In addition, preferably, when the most recent positioned position measured by the positioning means is away from the immediately preceding positioned position by a predetermined distance or more and the most recent positioned position is not located on the route, the route display control means slides and displays the route so that the intersection point when a perpendicular line is drawn from the most recent positioned position to the route closest to the most recent positioned position overlaps with the most recent positioned position.
According to this configuration, if the device deviates from the route to the destination, the route can be displayed in a sliding manner as described above, preventing the route display from disappearing from the display unit, thereby preventing the user from losing sight of the route.

In addition, preferably, a correction means for correcting the spot route is provided,
When the initial position is not located on the route passing through the spots, the correction means may set a line segment connecting the closest spot in the direction toward the destination and the initial position as the initial route on the route passing through the spots, instead of a line segment connecting the closest spot in the direction toward the destination from the closest spot to the initial position.
According to this configuration, if the initial position is off the spot via route, the spot via route SR starting from the initial position can be displayed by correcting the spot via route, making it easier to visually grasp the spot via route.

In a preferred embodiment, the system further comprises an acquisition unit for acquiring POI (Point Of Interest) information included in the space photographed by the imaging unit,
The route display control means may display the POI information included in the space acquired by the acquisition means.
According to this configuration, by displaying only the POI information contained in the space photographed by the imaging means, it is possible to improve the visibility of the screen in which the route is displayed superimposed on the image of the space.

In order to solve the above problems, the route display method of the present invention comprises:
A communication means capable of communicating with access points provided at each spot in the facility;
An imaging means;
A route display method in a route display device comprising:
a positioning step of measuring a current position of the device based on position information of each of the spots and a communication status with an access point provided at each of the spots;
a route creation step of creating a route from the current position determined in the positioning step to an initial position to a destination;
a route display control step of displaying the route, which is aligned with the orientation of the space in the facility photographed by the imaging means, superimposed on an image of the space;
Including,
The route creation step includes:
if an angle between a reference line segment connecting a predetermined spot closest to the initial position and a spot closest to the initial position in a direction from the predetermined spot toward the destination, and a line segment connecting the initial position to the destination in a straight line, exceeds a predetermined angle, a spot passing route is created as the route from the spot closest to the initial position to the destination via each spot,
If an angle between the reference line segment and a line segment connecting the initial position to the destination in a straight line is within a predetermined angle, a direct route going in a straight line from the initial position to the destination is generated as the route.
It is characterized by the following.

<Configuration of route display device>
FIG. 1 is a block diagram showing the functional configuration of a route display device 10. As shown in FIG.
The route display device 10 is a mobile terminal device (e.g., a smartphone) that searches for a route (travel route) to a destination and displays the route as a search result. As shown in Fig. 1, the route display device 10 includes a control unit 11, a storage unit 12, an operation unit 13, a display unit 14, a communication unit 15, and an image capture unit 16.

The control unit (positioning means, route creation means, route display control means, correction means, acquisition means) 11 includes a CPU (Central Processing Unit) that executes various programs stored in the memory unit 12 to perform predetermined calculations and control each unit, and a memory that serves as a work area when the programs are executed (both not shown). The control unit 11 executes various processes in cooperation with the programs stored in the memory unit 12.

The storage unit 12 is composed of a non-volatile semiconductor memory, etc. The storage unit 12 stores system programs and application programs (e.g., an AR navigation app, etc.) executed by the control unit 11, data required for executing these programs, etc.

The operation unit 13 has various function keys, accepts input of each key being pressed by the user, and outputs the operation information to the control unit 11. The operation unit 13 also has a touch panel or the like in which transparent electrodes are arranged in a grid pattern so as to cover the surface of the display unit 14, detects the position pressed by a finger, a touch pen, or the like, and outputs the position information to the control unit 11 as operation information.

The display unit 14 is configured with an LCD (Liquid Crystal Display) or the like, and displays various information on the screen in accordance with display control signals from the control unit 11.

The communication unit (communication means) 15 performs wireless communication via a base station or access point on a communication network using a mobile communication or Wi-Fi (registered trademark) communication method.

The photographing unit (imaging means) 16 photographs the scenery based on the user's operation, generates image data of the scenery, and outputs it to the control unit 11.

<Route Guidance Processing>
Next, a route guidance process performed by the route display device 10 will be described with reference to Fig. 2. This route guidance process is executed when an AR navigation application installed in the route display device 10 is started.

The following describes the route guidance process, assuming that the user launches the AR navigation app within a certain station. Note that while the route guidance process is being executed, the route display device 10 is successively locating its own current location based on the position information of the access points installed at each spot SP within the station and the communication status with the access points installed at each spot SP, as shown in FIG. 5.

FIG. 2 is a flowchart showing a control procedure for the route guidance process.
As shown in FIG. 2, when the route guidance process is started, first, the control unit 11 of the route display device 10 accepts a destination specification from the user via the operation unit 13 (step S1).

Next, the control unit 11 receives an instruction to start a route search from the user via the operation unit 13 (step S2).

Next, the control unit 11 sets the measured current position as the initial position and determines whether the angle between the line segment connecting the initial position and the destination in a straight line and the reference line segment is within ±15° (step S3).

Here, the reference line segment is a line segment that connects the spot SP that is closest to the initial position in the direction from the spot SP toward the destination, and the spot SP that is closest from this spot SP in the direction toward the destination.
For example, as shown in Fig. 5, when the initial position P0 is the position of the star in the figure and the destination is the ABC central entrance, the line segment connecting the spot SP2 closest to the initial position P0 in the direction toward the ABC central entrance (destination) from the spot SP1 closest to the initial position P0 to the spot SP2 closest to the spot SP2 in the direction toward the ABC central entrance becomes the reference line segment Ls. Also, as shown in Fig. 6, when the initial position P0 is the position of the star in the figure and the destination is the XYZ Mart, the line segment connecting the spot SP2 and the spot SP3 becomes the reference line segment Ls, similar to the above-mentioned case where the destination is the ABC central entrance.

In step S3, if it is determined that the angle between the line segment connecting the initial position and the destination in a straight line and the reference line segment is within ±15° (step S3; YES), the control unit 11 creates a direct route connecting the initial position and the destination in a straight line (step S4).
For example, as shown in Figure 5, if it is determined that the angle between the line segment connecting the initial position P0 and the destination, the ABC Central Exit, in a straight line and the reference line segment Ls is within ±15°, the control unit 11 creates a direct route DR connecting the initial position P0 and the destination, the ABC Central Exit, in a straight line, as shown in Figure 7.

Furthermore, in step S3, if it is determined that the angle between the line segment connecting the initial position and the destination in a straight line and the reference line segment is not within ±15° (step S3; NO), the control unit 11 creates a spot-via-spot route from the spot SP closest to the initial position through each spot SP to the destination (step S5).
For example, as shown in FIG. 6, if it is determined that the angle between the line segment connecting the initial position P0 and the destination XYZ Mart in a straight line and the reference line segment Ls is not within ±15°, the control unit 11 creates a spot-via-spot route SR that runs from the spot SP1 closest to the initial position P0 to the destination XYZ Mart via each of the spots SP2 to SP4, as shown in FIG. 8.

Next, the control unit 11 determines whether the initial position is on the spot route created in step S5 (step S6).

If it is determined in step S6 that the initial position is not on the spot via route created in step S5 (step S6; NO), the control unit 11 corrects the spot via route (step S7). Specifically, as shown in FIG. 8, if it is determined that the initial position P0 is not on the spot via route SR, the control unit 11 deletes the section connecting spots SP1 and SP2, which is the initial route, from the spot via route SR, as shown in FIG. 9, and corrects the section connecting the initial position P0 and spot SP2 as the initial route of the spot via route SR.

Also, if it is determined in step S6 that the initial position is on the spot route created in step S5 (step S6; YES), the control unit 11 skips step S7 and proceeds to step S8.

Next, the control unit 11 causes the display unit 14 to display the direct route created in step S4, or the route via spot created in step S5, or the route via spot corrected in step S7 (step S8). Specifically, when the direct route or the route via spot is displayed on the display unit 14, the route display device 10 is switched to a photographing mode, and the control unit 11 causes the direct route or the route via spot that matches the orientation of the space within the station photographed by the photographing unit 16 to be superimposed on an image of the space.

FIG. 10 is a diagram showing an example of an AR navigation screen 141 on which the direct route DR shown in FIG. 7 is displayed superimposed on an image of the space inside the station.
10, the AR navigation screen 141 displays a direct route DR that corresponds to the display mode of the AR navigation, and also displays text information at the top of the screen, such as the name of the destination "ABC Central Exit," the distance to the destination "80 m to destination," and the time required to reach the destination "1 minute." Also, on the AR navigation screen 141, a symbol M (e.g., a G in a circle) representing the destination is displayed superimposed on an image (not shown) of the destination, ABC Central Exit.

FIG. 11 is a diagram showing an example of an AR navigation screen 142 on which the spot via route SR shown in FIG. 9 is displayed superimposed on an image of the space inside the station.
As shown in FIG. 11, the AR navigation screen 142 displays a spot passing route SR that corresponds to the display mode of the AR navigation, and also displays text information at the top of the screen, such as the name of the destination "XYZ Mart," the distance to the destination "120 m to destination," and the time required to reach the destination "1 minute 30 seconds."

Next, the control unit 11 performs a route display correction process (step S9). The details of the route display correction process will be described later.

Next, the control unit 11 performs a POI (Point Of Interest) display control process (step S10). The POI display control process will be described in detail later.

Next, the control unit 11 determines whether or not the destination has been reached based on the measured current position (step S11).

If it is determined in step S11 that the destination has been reached (step S11; YES), the control unit 11 notifies the user of arrival at the destination (step S12) and ends the route guidance process.

If it is determined in step S11 that the destination has not been reached (step S11; NO), the control unit 11 returns the process to step S8 and repeats the subsequent processes.

<Route Display Correction Processing>
Next, the route display correction process will be described with reference to Fig. 3. Fig. 3 is a flowchart showing a control procedure of the route display correction process.

As shown in FIG. 3, when the route display correction process is started, the control unit 11 determines whether the most recent positioning position is on the route (direct route or route via spot) displayed on the AR navigation screen (step S101).

If it is determined in step S101 that the most recent positioning position is on the route displayed on the AR navigation screen (step S101; YES), the control unit 11 returns the process to the route guidance process (see FIG. 2).

In addition, if it is determined in step S101 that the most recently positioned position is not on the route displayed on the AR navigation screen (step S101; NO), the control unit 11 determines whether the most recently positioned position is a predetermined distance or more away from the immediately previous positioned position (step S102).

If it is determined in step S102 that the most recently positioned position is not a predetermined distance or more away from the immediately preceding positioned position (step S102; NO), the control unit 11 returns the process to the route guidance process (see FIG. 2).

In addition, if it is determined in step S102 that the most recently positioned position is a predetermined distance or more away from the immediately preceding positioned position (step S102; YES), the control unit 11 slides and displays the route so that the intersection point of a perpendicular line drawn from the most recently positioned position to the route closest to the most recently positioned position overlaps with the most recently positioned position (step S103), and the process returns to the route guidance process (see FIG. 2).

12(a) to 12(c) are diagrams for explaining the slide display of the above-mentioned route.
As shown in Fig. 12(a), when it is determined that the nearest positioning position P1 is away from the immediately preceding positioning position P0 by a predetermined distance or more, the control unit 11 slides and displays the direct route DR so that an intersection point CP of a perpendicular line drawn from the nearest positioning position P1 to the direct route DR closest to the nearest positioning position P1 overlaps with the nearest positioning position P1, as shown in Fig. 12(b) and Fig. 12(c). Note that, in the above explanation, the direct route DR is described as the subject, but the spot via route SR may also be subject to slide display.

<POI display control process>
Next, the POI display control process will be described with reference to Fig. 4. Fig. 4 is a flowchart showing the control procedure of the POI display control process.

As shown in FIG. 4, when the POI display control process is started, the control unit 11 determines whether or not there is any POI information contained within the space photographed by the photographing unit 16, for example, by referring to a POI database in an external server (not shown) that manages POI information via the communication unit 15 (step S111).

If it is determined in step S111 that there is no POI information contained within the space photographed by the photographing unit 16 (step S111; NO), the control unit 11 returns the process to the route guidance process (see FIG. 2).

In addition, in step S111, if it is determined that there is POI information contained within the space photographed by the photographing unit 16 (step S111; YES), the control unit 11 acquires the POI information contained within the space from the external server that manages the above-mentioned POI via the communication unit 15 (step S112). For example, as shown in FIG. 13, if it is determined that there is POI information I1 and I2 within the space V photographed by the photographing unit 16, the control unit 11 acquires the POI information I1 and I2 contained within the space V from the above-mentioned external server via the communication unit 15.

Next, the control unit 11 displays the POI information acquired in step S112 superimposed on the image of the space captured by the image capture unit 16 (step S113). For example, when the above-mentioned POI information I1 and I2 are acquired, the control unit 11 displays the POI information I1 and I2 superimposed on the AR navigation screen 141 (a screen displaying the image of the space V captured by the image capture unit 16) as shown in FIG. 14. Then, the control unit 11 returns the process to the route guidance process (see FIG. 2).

As described above, the route display device 10 of the present embodiment measures the current position of the device 10 based on the position information of each spot SP and the communication status with the access point provided at each spot SP, creates a route from the measured current position to the initial position P0 to the destination, and displays the route aligned with the spatial orientation of the station premises (facility) photographed by the photographing unit 16, superimposed on the image of the space (AR navigation screens 141, 142). In addition, when the angle formed by the reference line segment Ls connecting a predetermined spot SP close to the initial position P0 and the closest spot SP in the direction from the spot SP toward the destination, and the line segment connecting the initial position P0 to the destination in a straight line exceeds ±15°, the route display device 10 creates a spot-via-route SR from the spot SP1 closest to the initial position P0 to the destination via each of the spots SP2 to SP4. In addition, when the angle between the reference line segment Ls and the line segment connecting the initial position P0 in a straight line to the destination is within ±15°, the route display device 10 creates a direct route DR that goes in a straight line from the initial position P0 to the destination as the above route.
Therefore, according to the route display device 10 of this embodiment, either a spot via route SR or a direct route DR is created depending on the destination, and the route that is aligned with the orientation of the space within the facility photographed by the photographing unit 16 is displayed superimposed on an image of the space, making it easier to understand whether to proceed in a straight line from the current position to the destination or to proceed while turning corners.

In addition, in the case where the most recent positioned position is away from the immediately preceding positioned position by a predetermined distance or more and the most recent positioned position is not located on the route, the route display device 10 of this embodiment slides and displays the route so that the intersection point CP when a perpendicular line is drawn from the most recent positioned position to the route closest to the most recent positioned position overlaps with the most recent positioned position.
Therefore, according to the route display device 10 of this embodiment, if the device 10 deviates from the route to the destination, the route is displayed in a sliding manner as described above, thereby preventing the route display from going off screen on the display unit 14 and preventing the user from losing sight of the route.

In addition, when the initial position P0 is not located on the spot passing route SR, the route display device 10 of this embodiment uses, instead of the line segment connecting the spot SP1 closest to the initial position P0 and the spot SP2 closest in the direction from the spot SP1 toward the destination, the line segment connecting the initial position P0 and the spot SP2 closest in the direction toward the destination as the initial route on the spot passing route SR.
Therefore, according to the route display device 10 of this embodiment, if the initial position P0 is off the spot via route SR, the spot via route SR can be corrected to display the spot via route SR starting from the initial position P0, making it easier to visually grasp the spot via route SR.

In addition, the route display device 10 of this embodiment acquires POI (Point Of Interest) information contained in the space V photographed by the photographing unit 16, and displays the POI information I1, I2 contained in the acquired space V.
Therefore, according to the route display device 10 of this embodiment, the visibility of the AR navigation screens 141, 142 can be improved by displaying only the POI information I1, I2 contained within the space V displayed on the AR navigation screens 141, 142.

Although the present invention has been specifically described based on the embodiment, the present invention is not limited to the above embodiment and can be modified without departing from the gist of the present invention.
For example, in the above embodiment, if the angle between the reference line segment Ls and the line segment connecting the initial position P0 to the destination in a straight line exceeds ±15°, a spot-via route SR is created, whereas if the angle between the reference line segment Ls and the line segment connecting the initial position P0 to the destination in a straight line is within ±15°, a direct route DR is created. However, the angle used as the basis for determining which route to create is not limited to ±15°, and for example, the angle may be set or changed as appropriate based on user operation.

In the above embodiment, access points may be provided corresponding to each spot within the station, such as stairs, escalators, elevators, and slopes, so that a user can select and create either a normal route that uses stairs or escalators to reach the destination, or a barrier-free route that does not use stairs or escalators to reach the destination, based on the user's operation. In such a case, it is preferable to display the normal route and the barrier-free route in a manner that allows each route to be distinguished (for example, the normal route is displayed in red and the barrier-free route is displayed in yellow, etc.).

In the above embodiment, if the device 10 deviates from the route to the destination, the route is displayed in a sliding manner. In such a case, the finish point after the sliding display will differ from the original finish point (destination). Therefore, for example, a re-search button may be provided on the AR navigation screens 141, 142, and the user may operate the re-search button to re-search (re-create) the route to the destination accepted in step S1 of the route guidance process (see FIG. 2).

In addition, in the above embodiment, only the POI information I1, I2 contained within the space V displayed on the AR navigation screens 141, 142 is displayed, but if the number of POI information contained within this space V exceeds a predetermined number (e.g., 10), for example, it is also possible to display up to a predetermined number of POI information items close to the current position.
