[0075] [Structure of inspection support device]

[0076] The inspection support device 10 of this embodiment is configured as a device that automatically extracts a damaged area that appears on the surface of a concrete structure such as a bridge from an image, and then automatically detects the cause of the damage and outputs it.

[0077] figure 1 It is a functional block diagram of the first embodiment of the inspection support device.

[0078] As shown in the figure, the inspection support device 10 of this embodiment includes an image acquisition unit 11 that acquires an image, a damaged area extraction unit 12 that extracts a damaged area that appears on the surface of a concrete structure from the acquired image, and acquires an imaging surface. The photographed surface information acquiring unit 13 of the information, the damaged surface information acquiring unit 14 acquiring the information of the damaged surface, the gravity direction determining unit 15 judging the...

no. 2 approach

[0139] Figure 9 It is a functional block diagram of the second embodiment of the inspection support device.

[0140] The inspection support device 10 of the present embodiment differs from the inspection support device 10 of the above-mentioned first embodiment in that it further includes a correction unit 21 that corrects the damage region extraction result and the causative site detection result. Therefore, only the parts different from the inspection support device 10 of the above-mentioned first embodiment will be described below.

[0141] In the extraction of the damaged area and the detection of the causal part, false detection may occur. The inspection support device 10 according to the present embodiment has a function of correcting the result when an erroneous detection occurs.

[0142] The correcting unit 21 receives the correction of the extracted result of the damaged area and the detected result of the causative site via an input device (keyboard, mouse, touch ...

no. 3 approach

[0151] Figure 12 It is a functional block diagram of the third embodiment of the inspection support device.

[0152]The inspection support device 10 of the present embodiment differs from the inspection support devices 10 of the above-mentioned first and second embodiments in that it further includes a quantization unit 22 that quantifies the damaged area and the causative site. Therefore, only the parts different from the inspection support device 10 of the first embodiment and the second embodiment described above will be described below.

[0153] The quantization unit 22 calculates the area and / or color of the extracted damaged region from the image based on the extraction result of the damaged region extracting unit 12 , and quantifies the damaged region. In addition, based on the detection result of the causative site detection unit 17, at least one of the width, length, area, etc. of the detected causal site is obtained from the image, and the causal site is quantified...

Abstract

Provided are an inspection assistance device, an inspection assistance method, and an inspection assistance program for a concrete structure, which are capable of automatically detecting a damaged area and the part that has caused the damage. The present invention comprises: an image acquisition unit (11) which acquires an image of a concrete structure to be inspected; a damaged area extraction unit (12) which extracts a damaged area (water leakage, free lime, or the like) that has appeared on the surface of the concrete structure from the acquired image; a cause part detection unit (17) which when the damaged area is extracted, on the basis of the result of extraction of the damaged area, detects a part that has caused the damage (a crack, a seam, a joint, a peeled portion, or the like) from the image; and an output unit (19) which outputs the result of extraction of the damaged area and a result of detection of the part that has caused the damage.

Description

technical field [0001] The present invention relates to a point inspection auxiliary device, a point inspection auxiliary method and a point inspection auxiliary program of concrete structures. Background technique [0002] In inspections of concrete structures such as bridges, work is performed to confirm the presence or absence of damage (for example, water leakage, free lime, etc.). This work is performed visually by an inspector close to the concrete structure. However, a large amount of labor is required for visual inspection. [0003] In Patent Document 1, as an inspection support device for concrete structures, the following technology is described: acquiring an image obtained by photographing a concrete structure to be inspected, analyzing the image, and automatically detecting damage (the presence or absence of cracks, cracks, etc.) pattern, whether there is peeling of concrete, whether there is exposed steel bar, whether there is water leakage, whether there is f...
