Description

The present invention relates to a bar arrangement inspection device and a bar arrangement inspection method, and more particularly to a bar arrangement inspection device for correcting a measurement error caused by a photographed image of the bar arrangement, and a bar arrangement inspection method.

At the construction site, after assembling the reinforcing bars and before placing concrete, it is inspected whether the construction conditions of the reinforcing bars are in accordance with the design specifications. This test is also called a bar arrangement test. In the conventional bar arrangement inspection, the inspector collates the inspection target with the design drawing and inspects the inspection, which requires a huge amount of time and effort.

In recent years, with the spread of digital cameras and the progress of digital image processing technology, various measurement techniques using three-dimensional captured images have been proposed (for example, Patent Document 1). It is also possible to perform a bar arrangement inspection using a three-dimensional photographed image.

Japanese Unexamined Patent Publication No. 2009-2798

In the measurement based on the captured image, the image quality of the captured image is important. Reinforcing bars are often photographed outdoors, so exposure conditions may not be appropriate for some reinforcing bars. For example, a part of the reinforcing bar may be a shadow or may be reflected in the opposite direction. When the measurement is performed with such a photographed image, the reinforcing bar photographed under inappropriate exposure conditions may not be extracted as the reinforcing bar. However, because of the shooting at the construction site, it is often not possible to redo the shooting after a measurement error is found.
In view of the above problems, the present invention provides a bar arrangement inspection device and a bar arrangement inspection method capable of correcting an error without re-shooting when an error is found in the measurement result in the bar arrangement inspection based on the photographed image. The purpose is to provide.

In order to achieve the above object, the bar arrangement inspection device has a measuring unit that measures the state of the bar arrangement based on the image of the bar arrangement taken and generates the measurement data of the bar arrangement, and the bar arrangement image. An inspection image generation unit that generates an inspection image obtained by synthesizing the measurement data, and a correction that instructs the measurement unit to correct the measurement data when the operation unit performs a correction operation on the measurement data. The inspection image generation unit is provided with a unit, and after the correction by the correction unit, the inspection image generation unit generates the inspection image so that the measured data after the correction and the measurement data before the correction can be distinguished.

According to the present invention, it is possible to provide a bar arrangement inspection device capable of correcting an error without re-shooting when an error is found in the measurement result in the bar arrangement inspection based on the photographed image.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall view of the bar arrangement inspection system 1 according to the present invention. The bar arrangement inspection system 1 includes a camera 10 and an information processing device 20. The camera 10 and the information processing device 20 are connected by a network NW. The network NW is a LAN (Local Area Network) or the Internet.

The camera 10 is a 3D camera (also called a three-dimensional camera) that captures the bar arrangement H. The information processing apparatus 20 acquires a bar arrangement image taken by the camera 10 and measures the state of the bar arrangement. The information processing device 20 may be a normal PC (Personal Computer) or a tablet terminal. A bar arrangement inspection device is mounted on the information processing device 20.

FIG. 1 shows a state in which a bar arrangement H is photographed by a camera 10 attached to a tripod. In order to improve the measurement accuracy, it is desirable that the camera 10 is fixed to a tripod. The camera 10 may be a combination of two monocular cameras. In this example, as the reinforcing bar H, a combination of horizontal reinforcing bars (also called horizontal reinforcing bars) and vertical reinforcing bars (vertical reinforcing bars) in a grid pattern is shown. Further, the bar arrangement H is often composed of a plurality of layers instead of one layer. In this example, an example of two layers is shown. The bar arrangement on the side closer to the camera 10 is referred to as the anterior bar arrangement HF, and the bar arrangement on the rear side of the anterior bar arrangement HF is referred to as the posterior bar arrangement HB.

FIG. 2 is a functional block diagram relating to the camera 10 and the information processing device 20. The camera 10 includes a control unit 100, an image pickup unit 110, a 3D image generation unit 120, a storage unit 140, a communication unit 180, an operation unit 182, a display unit 184, and the like.

The control unit 100 is a control unit that comprehensively controls the entire camera 10. The image pickup unit 110 has a right image pickup unit 110R and a left image pickup unit 110L. The right image pickup unit 110R is an image pickup unit that captures an image of the right visual field of the photographer. The left image pickup unit 110L is an image pickup unit that captures an image of the left visual field of the photographer.

The right image pickup unit 110R and the left image pickup unit 110L each include a lens unit, an image sensor, an image processing unit, and the like (all not shown). The 3D image generation unit 120 generates a three-dimensional captured image by synthesizing the captured image by the right imaging unit 110R and the captured image by the left imaging unit 110L.

The storage unit 140 stores various programs and data or data of captured images. The storage unit 140 stores a three-dimensional image and left and right captured images. The storage unit 140 may include not only the built-in storage medium but also a detachable storage medium. The storage unit 140 is, for example, a flash memory.

The communication unit 180 is an interface for performing various information communication with an external device. The communication unit 180 transmits the captured image to the information processing apparatus 20 via the network NW, for example, by a wireless LAN or the like. The left and right captured images may be transmitted to the information processing apparatus 20 together with the three-dimensional captured images.

The operation unit 182 is an input means for inputting a shooting instruction, a shooting condition setting, and the like. The operation unit 182 is, for example, a touch panel or an operation button. The display unit 184 displays various setting screens such as a live view image, a shot image, and shooting conditions. The display unit 184 is, for example, an LCD or an organic EL.

The information processing device 20 includes a control unit 200, an image acquisition unit 210, a face-to-face conversion unit 212, a measurement unit 220, a correction unit 230, a storage unit 240, an inspection image generation unit 250, a communication unit 280, an operation unit 282, and a display unit 284. It also has a display control unit 290 and the like.

The control unit 200 is a control unit that comprehensively controls the entire information processing apparatus 20. The image acquisition unit 210 acquires a photographed image (three-dimensional image and / or left and right photographed image) of the bar arrangement photographed by the camera 10 and stores it in the storage unit 240 as the photographed image data 242. The image acquisition unit 210 acquires captured image data captured by the camera 10 from the communication unit 280, a storage medium, or the like, and stores the captured image data in the storage unit 240. The photographed image of the bar arrangement is also referred to as a bar arrangement image.

The face-to-face conversion unit 212 generates a face-to-face conversion image by face-to-face conversion of the captured image of the bar arrangement taken by the camera 10. For example, the face-to-face transformation unit 212 estimates the homography transformation matrix as a face-to-face transformation parameter by designating the four corners of arbitrary rectangles on the reinforcing bars arranged in a grid pattern of the bar arrangement H, and the positiveness of the homography transformation matrix is estimated. The captured image is face-to-face converted based on the pair conversion parameter, and a face-to-face conversion image is generated. The face-to-face conversion unit 212 stores the face-to-face conversion image in the storage unit 240 as the face-to-face conversion image data 244.

When the bar arrangement H is composed of the front bar arrangement HF and the posterior bar arrangement HB, the facing conversion unit 212 performs the front bar arrangement based on the three-dimensional information of the three-dimensional image acquired from the camera 10. The HF is determined, and the face-to-face conversion parameter is calculated based on the parameter of the anterior bar arrangement HF. Then, the face-to-face conversion unit 212 may perform face-to-face conversion of the captured image based on the calculated face-to-face conversion parameter to generate a face-to-face conversion image.

FIG. 3 is a diagram for explaining an outline of the face-to-face conversion. The image E1 is a captured image before the face-to-face conversion. The image E1 is an image in which the reinforcing bar H is taken from the diagonally left side. Note that FIG. 3 shows only the anterior bar arrangement HF. The image E1 is directly converted into the image E2 by the face-to-face conversion unit 212.

Return to FIG. The measurement unit 220 measures the dimensions of the bar arrangement based on the face-to-face conversion image, and stores the measurement data in the storage unit 240. The measuring unit 220 includes a reinforcing bar extraction unit 222, a reinforcing bar center determination unit 224, and an interval calculation unit 226.

The reinforcing bar extraction unit 222 extracts the reinforcing bar region by specifying the contour position of the reinforcing bar from the image face-to-face converted by the facing conversion unit 212, for example, by binarization processing and edge detection processing. The reinforcing bar center determination unit 224 determines the reinforcing bar center from the extracted reinforcing bar region. The interval calculation unit 226 calculates the interval between the reinforcing bars based on the three-dimensional information of the acquired three-dimensional image and the reinforcing bar center determined by the reinforcing bar center determining unit 224.

The correction unit 230 instructs the measurement unit 220 to correct the measurement data. The correction unit 230 instructs the measurement unit 220 to make corrections according to the instructions input from the operator to the operation unit 282. For example, the operator looks at the image of the reinforcing bar arrangement displayed on the display unit 284, and when the center of the reinforcing bar is determined to be in the wrong position, the operator moves the center of the reinforcing bar to the correct position. This is because if the shooting condition of the reinforcing bar is poor, an error may occur in the reinforcing bar extraction process. When the correction unit 230 gives a correction instruction, the measurement unit 220 corrects the measurement data in response to the correction instruction.

The storage unit 240 stores captured image data 242, face-to-face conversion image data 244, measurement data 246, design data 248, inspection result 249, and the like. Design data is data showing the arrangement of each reinforcing bar such as columns, beams, walls, slabs, and foundations, as well as dimensions, quantities, and types. The design data is data based on the bar arrangement diagram. The inspection result 249 is an inspection result (inspection OK or inspection NG) input from the inspector. The storage unit 240 is, for example, a flash memory. The storage unit 240 may include not only the built-in storage medium but also a detachable storage medium.

The inspection image generation unit 250 generates an inspection image by synthesizing the measurement data and the design data measured by the measurement unit 220 with the face-to-face conversion image. Specific examples of the inspection image will be described later in FIGS. 6 and later.

The communication unit 280 is an interface for performing various information communication with an external device. The communication unit 280 receives, for example, a captured image from the camera 10 via the network NW via a wireless LAN.

The operation unit 282 is an input means for inputting various instructions, processing conditions, and the like. The operation unit 282 is, for example, a touch panel, a mouse, or a keyboard. The display unit 284 displays an image and a processing menu. The display unit 284 is, for example, an LCD or an organic EL. The display control unit 290 outputs various captured images including inspection images and information to the display unit 284.

FIG. 4 is a block diagram showing a hardware configuration example of the information processing apparatus 20. The information processing device 20 includes a communication unit 280, an operation unit 282, a display unit 284, a display control unit 290, an input / output IF (Interface) 292, a CPU (Central Processing Unit) 300, a RAM (Random Access Memory) 302, and a ROM (Read). Only memory) 304 and bus 306.

The input / output IF292 transmits / receives data to / from the connected device. The connected device is an operation unit 282 or a storage unit 240. The CPU 300 reads a control program from the ROM 304 and executes various control processes according to the read control program. The RAM 302 is a work area for temporarily storing various data such as a control program and images taken from the camera 10. The RAM 302 is, for example, a DRAM (Dynamic Random Access Memory). The ROM 304 is a non-volatile storage unit that stores control programs, various data, and the like. The ROM 304 is, for example, a flash memory. The CPU 300 is connected to the RAM 302, ROM 304, etc. by a bus 306.

The control unit 200, the image acquisition unit 210, the face conversion unit 212, the measurement unit 220, and the inspection image generation unit 250 are realized by software processing by the CPU 300 that has read the program. The bar arrangement inspection device is composed of a face-to-face conversion unit 212, a measurement unit 220, and an inspection image generation unit 250. The control unit 200 is also referred to as a processing unit.

FIG. 5 is a flowchart for explaining the procedure of the bar arrangement inspection image display processing. The bar arrangement inspection image display process is executed by the control unit 200 of the information processing apparatus 20, the image acquisition unit 210, the face-to-face conversion unit 212, the measurement unit 220, the inspection image generation unit 250, and the like.

When the bar arrangement H is photographed by the camera 10 by the photographer, the photographed image (three-dimensional image and the left and right photographed images) of the bar arrangement H is transmitted from the camera 10 to the information processing apparatus 20. The transmitted captured image is acquired by the image acquisition unit 210. The control unit 200 determines whether or not the captured image has been acquired by the image acquisition unit 210 (step S10). The control unit 200 loops in step S10 until the captured image is acquired by the image acquisition unit 210 (NO in step S10).

The image acquisition unit 210 stores the acquired captured image as captured image data 242 in the storage unit 240. When the control unit 200 determines that the captured image has been acquired by the image acquisition unit 210 (YES in step S10), the control unit 200 proceeds to step S12.

The face-to-face conversion unit 212 performs face-to-face conversion of the shot image based on the three-dimensional information of the shot image to generate a face-to-face conversion image (step S12). The reinforcing bar extraction unit 222 extracts the reinforcing bar region from the face-to-face conversion image (step S14). When the reinforcing bar H has a plurality of layers, the reinforcing bar extraction unit 222 measures the front reinforcing bar HF.

The reinforcing bar center determination unit 224 specifies the contour position of the reinforcing bar for the extracted reinforcing bar region by, for example, binarization processing and edge detection processing, and determines the center of the contour as the reinforcing bar center line (axis line) (step S16). ). The interval calculation unit 226 calculates the interval between the reinforcing bars by the center line of each reinforcing bar based on the three-dimensional information (step S18).

The measuring unit 220 generates measurement data from the reinforcing bar center line determined by the reinforcing bar center determining unit 224 and the reinforcing bar spacing calculated by the interval calculating unit 226 (step S20). The measurement unit 220 stores the generated measurement data as measurement data 246 in the storage unit 240.

FIG. 6 is an example of an inspection image displayed on the display unit 284. The inspection image D1 of FIG. 6 is a screen in which only the face-to-face conversion image is displayed and the measurement data and the like are not displayed. In the inspection image, an instruction button is displayed at the bottom of the screen. The instruction button is a button included in the operation unit 282 and is operated by an inspector.

The measurement data button L1 is a button for selecting display / non-display of measurement data. The dashed frame around the button indicates the hidden state. The design data button L2 is a button for selecting display / non-display of design data. The broken line frame indicates the hidden state. The correction button L3 is a button for selecting on / off of the correction mode of the measurement data. The broken line frame indicates the hidden state. When the correction button L3 is clicked, the measurement unit 220 turns on the correction mode and accepts the correction by the operation unit 282. The inspection OK button L4 and the inspection NG button L5 are buttons for inputting the inspection results.

The control unit 200 determines whether the measurement data display on the inspection image is selected by the inspector (step S22). This is because if the measurement data is displayed when visually checking the bar arrangement or the like on the screen, it may be an obstacle.

When the control unit 200 determines that the measurement data display on the inspection image is not selected (No in step S22), it further determines whether the design data display on the inspection image is selected (step S24). When the control unit 200 determines that the design data display on the inspection image is not selected (No in step S24), the inspection image generation unit 250 generates and displays only the face-to-face conversion image as the inspection image (step). S26). The inspection image generation unit 250 reads the face-to-face conversion image data 244 from the storage unit 240 to generate a face-to-face conversion image, and the display control unit 290 outputs the face-to-face conversion image to the display unit 284. In this case, the inspection image D in FIG. 6 described above
1 is displayed.

When the control unit 200 determines that the design data display on the inspection image has been selected (Yes in step S24), the inspection image generation unit 250 reads out the facing conversion image data 244 and the design data 248 from the storage unit 240. An inspection image in which design data is combined with a face-to-face conversion image is generated (step S28).

An example of an inspection image in which design data is combined with a face-to-face conversion image is shown in inspection image D2 of FIG. 7. The reinforcing bar center line Cs according to the design data is shown by a broken line. When displaying the reinforcing bar center line Cs of the design data, the inspection image generation unit 250 displays the design data with one of the intersections of the vertical and horizontal reinforcing bars as a reference position. The inspection image D2 of FIG. 7 is an example in which the reinforcing bar center line Cs is displayed with the intersection K of the center of the reinforcing bar H1 and the center of the reinforcing bar H2 as a reference position. After step S26 and step S28, the process returns to step S22.

The control unit 200 determines that the display of the measurement data on the inspection image is selected (Yes in step S22), and further determines whether the display of the design data is selected (step S30). When the control unit 200 determines that the display of the design data is not selected (No in step S30), the inspection image generation unit 250 reads the face-to-face conversion image data 244 and the measurement data 246 from the storage unit 240, and faces each other. An inspection image in which measurement data is combined with the converted image is generated (step S32).

Further, when the control unit 200 determines that it is selected to display the design data on the inspection image (Yes in step S30), the inspection image generation unit 250 measures the facing conversion image data 244 from the storage unit 240. The data 246 and the design data 248 are read out, and an inspection image in which the measurement data and the design data are combined with the face-to-face conversion image is generated (step S34).

The display control unit 290 displays the inspection image generated by the inspection image generation unit 250 on the display unit 284 (step S36). An example of the inspection image in which the measurement data is synthesized by the process of step S32 is shown in the inspection image D3 of FIG. On the inspection image D3, the reinforcing bar center line Ct (solid line) based on the measurement data and the vertical and horizontal reinforcing bar spacing (unit: cm) are displayed. Further, an example of the inspection image in which the measurement data and the design data are combined by the processing of step S34 is shown in the inspection image D4 of FIG.

The control unit 200 determines whether or not the correction mode for correcting the measurement data is selected (step S38). When the control unit 200 determines that the correction mode is selected (Yes in step S38), the correction unit 230 receives the correction by the operation unit 282 from the inspector and instructs the measurement unit 220 to make the correction. The measurement unit 220 corrects the measurement data in response to an instruction from the correction unit 230 (step S40). The inspection image generation unit 250 generates an inspection image according to the correction instruction, and the corrected inspection image is displayed on the display unit 284. Further, the inspection image generation unit 250 updates the measurement data 246 of the storage unit 240 in response to the correction instruction (step S42).

10, 11, and 12 are examples (1), (2), and (3) in which the measurement error of the inspection image is corrected. FIG. 10 is an example in which an error occurs in the measurement because a part of the reinforcing bar could not be extracted. The inspection image D10 is an inspection image in which only the measurement data is displayed, and is an inspection image of an error before correction. In the inspection image D10, the reinforcing bar H2 is not extracted as the reinforcing bar among the four vertical reinforcing bars (H1 to H4). This is an example in which the reinforcing bar extraction unit 222 fails to extract the reinforcing bar H2 because the reinforcing bar H2 is overexposed due to the influence of the reflected light and blown out. Therefore, the value of the reinforcing bar spacing is also an erroneous value.

The inspector saw the inspection image D10 and understood that the reinforcing bar center line Ct was not displayed on the reinforcing bar H2 and that the reinforcing bar spacing value (100) was abnormal, and that the reinforcing bar H2 could not be extracted. recognize. The inspector clicks the correction button L3 to turn on the correction mode. Then, the inspector performs a correction operation of adding the reinforcing bar center line Ct to the center of the reinforcing bar H2 on the screen. The correction operation is an operation in which a new reinforcing bar center line Ct is called by an operation of a mouse or the like and moved to the center of the reinforcing bar H2.

The inspection image D11 in FIG. 10 is the corrected inspection image. The reinforcing bar center line Ct1 added by the modification may be displayed in a form different from the reinforcing bar center line Ct of the measurement data. This is to make it possible to distinguish between the measured data and the corrected data. In the inspection image D11, the added reinforcing bar center line Ct1 is displayed as a alternate long and short dash line. In addition, the interval is automatically calculated and displayed according to the addition or movement of the reinforcing bar center line Ct. The interval value changed by the modification may also be displayed in a manner different from the original value. In the inspection image D11, the interval values are surrounded by a frame to distinguish them.

FIG. 11 is an example in which an error occurs in the measurement because the reinforcing bar on the rear side is erroneously extracted. The inspection image D20 is an inspection image in which only the measurement data is displayed, and is an inspection image before correction. Among the four vertical reinforcing bars (H1 to H4), the reinforcing bar H2 is an example in which the adjacent posterior reinforcing bar HB is detected and an error occurs. This is because the reinforcing bar extraction unit 222 may mistakenly extract the reinforcing bar on the rear side.

The inspector looks at the inspection image D20 and recognizes that an error has occurred in the extraction of the reinforcing bar H2 depending on the position of the reinforcing bar center line Ct2 and the spacing value of the reinforcing bars. The inspector clicks the correction button L3 to turn on the correction mode. Then, the inspector performs a correction operation of moving the reinforcing bar center line Ct2 attached to the rear reinforcing bar arrangement HB to the center of the reinforcing bar H2 which is the original position by using a mouse or the like. The inspection image D21 in FIG. 11 is a modified inspection image. Similar to the inspection image D21, the modified reinforcing bar center line Ct3 is displayed as a alternate long and short dash line.

FIG. 12 is an example of modification in an inspection image displaying measurement data and design data. The content of the error is an example in which some reinforcing bars were not extracted, as in the case of FIG. The inspection image D30 is the same image as the inspection image D10 (before modification) of FIG. 10, and is an inspection image in which measurement data and design data are displayed.

In the inspection image D30, the reinforcing bar center line Cs (broken line) based on the design data is also displayed, so that the inspector clearly recognizes that the reinforcing bar H2 that should be originally detected has not been detected. As described in the inspection image D11 of FIG. 10, the inspector performs a correction operation of adding the reinforcing bar center line Ct4 to the center of the reinforcing bar H2 (see the inspection image D31). After step S42, the process proceeds to step S44.

Return to FIG. When the control unit 200 determines that the mode is not the correction mode (No in step S38), the control unit 200 determines whether or not the inspection result has been input (inspection OK button L4 or inspection NG button L5) (step S44). When the inspector clicks the inspection OK button L4 or the inspection NG button L5, it is determined that the inspection result has been input.

The inspector looks at the inspection image and clicks the inspection OK button L4 when it is determined that the reinforcement is correctly arranged. On the contrary, when the inspector determines that the reinforcement is not arranged correctly, the inspection NG button L5 is clicked. When the control unit 200 determines that the inspection result has not been input (No in step S44), the control unit 200 returns to step S22.

When the control unit 200 determines that the inspection result has been input (Yes in step S44), the control unit 200 stores the input inspection result in the storage unit 240 as the inspection result 249 (step S46). Then, the control unit 200 stores the photographed image data 242 in association with the corresponding face-to-face conversion image data 244, measurement data 246, design data 248, and inspection result 249 in the storage unit 240.

The inspection image is not limited to the face-to-face conversion image, and measurement data or design data may be combined with the captured image and displayed. FIG. 13 is a diagram showing an inspection image D40 in which measurement data is synthesized with respect to a captured image rather than a face-to-face conversion image. The captured image is the image E1 of FIG. The inspection image D40 is generated by the inspection image generation unit 250 converting and synthesizing the measurement data measured by the measurement unit 220 so as to correspond to the captured image.

According to the embodiment described above, even if an error occurs in the measurement data measured from the captured image, the error can be easily found by observing the inspection image. Then, since the error portion can be easily corrected while looking at the inspection image, even if an error occurs, the bar arrangement inspection can be completed without performing re-imaging. At present, there is a high possibility that measurement errors due to images will occur in bar arrangement inspections using captured images. Since it is difficult to re-photograph in the bar arrangement inspection, it is difficult to deal with a measurement error. This problem can be solved by applying the present embodiment to the bar arrangement inspection using the captured image. In addition, since the corrected content is reflected in the measurement data, it is easy to manage the data after the bar arrangement inspection.

Although it has been explained that the control unit 200, the image acquisition unit 210, the face-to-face conversion unit 212, the measurement unit 220, and the inspection image generation unit 250 are realized by software processing by the CPU 300, the present invention is not limited to this. The control unit 200 and the like are partially or wholly. It may be configured by hardware such as a gate array.

In addition, various inventions can be formed by an appropriate combination of the plurality of components disclosed in the above-described embodiment. For example, all the components shown in the embodiments may be combined as appropriate. In addition, components across different embodiments may be combined as appropriate.
