Description

[Technical field]

[0001] The present invention relates to an apparatus and program for supporting on-site inspection of road structures such as road surfaces, slopes, bridges, tunnels, culverts, and accessories on roads such as expressways and general roads. [Background technology]

[0002] In order to ensure that road structures such as road surfaces, slopes, bridges, tunnels, culverts, and accessories on expressways and general roads are always kept in a safe and functional condition, detailed inspections of each structure are carried out, and the results of the inspections are used to estimate the causes of abnormalities and to consider repair plans. For inspections, on-site surveys are carried out using various drawings and forms, and the results are accumulated as information for the maintenance and management of road structures.

[0003] Conventionally, as a device for supporting the creation of road inspection reports, there is known an inspection report creation support device described in Patent Document 1, for example. In this inspection report creation support device, a digital video camera mounted on an inspection vehicle captures moving images or captures still images continuously at a predetermined interval, acquires shooting position data using a GPS logger while capturing this road image data, converts this position information into kilometer post values, and if an abnormality is present in the captured road image data, records the kilometer post value and the abnormality result corresponding to the road image data, and creates an inspection report.

[0004] [Patent Document 1] JP 2018-147314 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the inspection report creation support device described in the above Patent Document 1, moving images are taken by a digital video camera mounted on an inspection vehicle, or still images are continuously taken at a predetermined interval while location information is recorded by a GPS logger, so one piece of road image data is associated with one piece of recorded location information. Therefore, even if the same deformed location is photographed from a different location, it may be recorded as a deformed location in a different location.

[0006] Therefore, an object of the present invention is to provide a site survey support device and program that can associate and record multiple images of a single inspection location when the images are taken by a camera device as being of the same inspection location. [Means for solving the problem]

[0007] The field survey support device of the present invention includes a continuous shooting means for continuously taking multiple images one by one using a camera device, a coordinate acquisition means for acquiring absolute coordinates of a current location, and a field survey information registration means for creating and registering field photo information that associates the multiple images continuously taken by the continuous shooting means with the absolute coordinates acquired by the coordinate acquisition means when the first image was taken.

[0008] According to the on-site survey support device of the present invention, when multiple images of one inspection location are taken successively by a camera device, these successively taken images are associated with the absolute coordinates obtained when the first image was taken, and on-site photo information is obtained in which one absolute coordinate is associated with multiple images for one inspection location.

[0009] It is preferable that the field survey information registration means further creates and registers location map information showing on a map the absolute coordinates acquired by the coordinate acquisition means when the first image was taken. This provides location map information showing on a map the absolute coordinates associated with the field photo information consisting of multiple images.

[0010] The field survey information registration means preferably further specifies and registers distance information of the mileposts of the road route based on the absolute coordinates acquired by the coordinate acquisition means when the first image is taken. This allows for the acquisition of field photograph information consisting of a plurality of images associated with the mileposts of the road route.

[0011] Of the multiple images captured by the continuous image capturing means, it is desirable that the first image is a close-up image of the inspection location. In the on-site investigation support device of the present invention, multiple images are associated with the absolute coordinates acquired when the first image is captured, so that by making the first image a close-up image close to the inspection location, it is possible to reduce the deviation between the inspection location and the absolute coordinates associated with the on-site photo information.

[0012] The field survey support program of the present invention is a program for causing a computer to function as a continuous photographing means for photographing a plurality of images one by one in succession with a camera device, a coordinate acquiring means for acquiring absolute coordinates of a current position, and a field survey information registration means for creating and registering field photograph information in which the plurality of images photographed in succession by the continuous photographing means are associated with the absolute coordinates acquired by the coordinate acquiring means when the first image was photographed. A computer that executes this program can achieve the same effects as the field survey support device of the present invention. Effect of the Invention

[0013] (1) A configuration including a continuous photographing means for continuously taking multiple images one by one using a camera device, a coordinate acquisition means for acquiring absolute coordinates of the current location, and a site inspection information registration means for creating and registering on-site photo information in which the multiple images continuously taken by the continuous photographing means are associated with the absolute coordinates acquired by the coordinate acquisition means when the first image was taken.By simply taking multiple images of one inspection location one by one using the camera device, on-site photo information in which multiple images are associated with one absolute coordinate for one inspection location can be obtained, making on-site inspections easier and shortening the time required to create on-site inspection reports, thereby improving the efficiency of on-site inspection work.

[0014] (2) The on-site survey information registration means further creates and registers location map information showing on a map the absolute coordinates acquired by the coordinate acquisition means when the first photograph is taken. This provides location map information showing on a map the absolute coordinates associated with on-site photo information consisting of multiple images, making it possible to easily check the inspection points of the on-site photo information consisting of multiple images on the map.

[0015] (3) The on-site survey information registration means further identifies and registers distance information of mileposts on the road route based on the location information acquired by the coordinate acquisition means when the first image is taken, thereby obtaining on-site photo information consisting of multiple images associated with the mileposts on the road route, and making it possible to easily check the on-site photo information of the inspection location identified by the milepost.

[0016] (4) The multiple images captured by the continuous shooting means include a close-up image of the inspection location, of which the first image is a close-up image close to the inspection location. This reduces the deviation between the inspection location and the absolute coordinates associated with the on-site photo information, making it possible to create an on-site inspection report based on more accurate location information.

[0018] FIG. 1 is an external view of a field survey support device according to an embodiment of the present invention, and FIG. 2 is a block diagram of the field survey support device of FIG.

[0019] As shown in Fig. 1, a field survey support device 1 in an embodiment of the present invention is composed of a computer 3 equipped with a touch panel 2. The touch panel 2 combines a display device and an input device for performing operations by touching the screen of the display device. The field survey support device 1 is realized by executing a field survey support program on the computer 3.

[0020] As shown in Figure 2, the field survey support device 1 has a memory means 10 for storing various information, a camera device 11, a continuous shooting means 12 for continuously shooting multiple images one by one using the camera device 11, a coordinate acquisition means 13 for acquiring the absolute coordinates of the current position, and a field survey information registration means 14 for registering the multiple images continuously shot by the continuous shooting means 12 in the memory means 10 as field survey information.

[0021] Next, the above means 10 to 14 will be described in detail with reference to FIGS. Fig. 3 shows an example of a menu screen displayed on the field survey support device 1. When "Register from photo" is clicked (selected) on the menu screen shown in Fig. 3, the mode switches to a continuous shooting mode using the continuous shooting means 12. Fig. 4 shows an example of a display screen of the field survey support device 1 in the continuous shooting mode.

[0022] The continuous photographing means 12 is capable of continuously photographing a plurality of images one by one by the camera device 11. FIG. 5 is an explanatory diagram showing on a map the positions and order of photographing a plurality of images one by one by the continuous photographing means 12. The inspector photographs a close-up image of a damaged position of a slope or the like as an inspection point as the first image (photograph 1), and photographs a distant image as the second image (photograph 2). As a guideline for the close-up image, it is desirable to photograph an image within a range of 1 m from the inspection point. On the other hand, it is desirable to photograph a distant image from a position 3 m or more from the inspection point. The third and subsequent images can be photographed freely (in the illustrated example, a distant image is photographed as the third image (photograph 3). The continuous photographing means 12 in this embodiment can photograph up to 10 images continuously.

[0023] In each image captured by the continuous shooting means 12, the absolute coordinates of the current position acquired by the coordinate acquisition means 13 when the image was captured are embedded as additional information such as Exif (Excangeable image file format). The coordinate acquisition means 13 acquires the absolute coordinates (longitude and latitude) of the current position using a satellite positioning system such as GNSS (Global Navigation Satellite System).

[0024] When the continuous photographing mode is ended, the site investigation information registration means 14 creates site photograph information in which the multiple images continuously photographed by the continuous photographing means 12 are associated with the absolute coordinates of the damage position of the slope, etc., acquired by the coordinate acquisition means 13 when the first image was photographed, and registers the site investigation information in the storage means 10. That is, as described above, the absolute coordinates of the current position acquired by the coordinate acquisition means 13 when each image was photographed are embedded as additional information in each image continuously photographed by the continuous photographing means 12, but the site investigation information registration means 14 uses only the absolute coordinates of the damage position of the slope, etc., acquired by the coordinate acquisition means 13 when the first image was photographed as the absolute coordinates of the current position, and creates site photograph information for the second and subsequent images as images photographed at the absolute coordinates of the damage position of the slope, etc., acquired by the coordinate acquisition means 13 when the first image was photographed. In other words, the absolute coordinates of the current position obtained when the second or subsequent photographs are taken are not used because they may be far from the location of damage such as a slope, and the on-site survey information registration means 14 creates on-site photo information for each inspection location that associates multiple images with one absolute coordinate closest to the inspection location.

[0025] Also, the field survey information registration means 14 creates location map information showing the absolute coordinates acquired by the coordinate acquisition means 13 when the first image was taken on a map as field photo information, and registers it in the storage means 10. FIG. 6 shows an example of a confirmation screen for field photo information registered by the field survey information registration means 14. When the continuous shooting mode is ended, as shown in FIG. 6, the field survey support device 1 displays, as field photo information, the close-up image (photo 1) taken as the first image and the distant-view image (photo 2) taken as the second image, as well as the detailed and wide-area location map automatically generated based on the reference scale as location map information, and the third and subsequent images. When the inspector clicks "Register" after checking, these are registered in the storage means 10. The reference scale of the location map is preset to 1 / 2500 for the detailed image and 1 / 10000 for the wide area, but can be changed. Also, it is possible to change, add, delete, etc. the photos on this confirmation screen.

[0026] In addition, in the on-site inspection information registration means 14, it is possible to input and register inspection information such as the inspection date, contents, inspector, project name, details, etc. on the inspection information input screen (see Figure 7) that is displayed by clicking "Next" shown in Figure 6.

[0027] Furthermore, in the field survey information registration means 14, the field survey information can be registered in the storage means 10 by clicking "Register" after checking all the photographs taken, location maps, inspection information, specifications information, etc. on the confirmation screen (see Figure 8) that is displayed by clicking "Next" shown in Figure 7.

[0028] In addition, when the memory means 10 stores information including the absolute coordinates and distance (the distance indicated by each distance marker (hereinafter sometimes referred to as "Kilometer Post" (KP)))) of each distance marker set at a predetermined interval on the road route as route information, the field survey information registration means 14 can identify the distance information of the distance marker on the road route based on the absolute coordinates acquired by the coordinate acquisition means 13 when the first image is taken, and automatically input it as KP information.

[0029] The field survey information registered in the storage means 10 by the field survey information registration means 14 configured as described above can be collected back at the office and output as a standard format form. Note that, in this embodiment, the absolute coordinates of the current location are embedded as additional information in all captured images, and only the absolute coordinates of the first image are used for registration by the field survey information registration means 14, but it is also possible to configure the absolute coordinates of the current location to be obtained only when the first image is captured.

[0030] As described above, according to the on-site inspection support device 1 in this embodiment, by simply taking multiple images of one inspection location one by one in succession using the camera device 11, on-site photo information in which one absolute coordinate and multiple images are associated with one inspection location can be obtained, making the on-site inspection easier and shortening the time required to create the on-site inspection report, thereby making the on-site inspection work more efficient.

[0031] Furthermore, in the on-site survey support device 1 of this embodiment, the first of the multiple images captured by the continuous shooting means 12 is a close-up image of the inspection location. By making the first image a close-up image close to the inspection location, the deviation between the inspection location and the absolute coordinates associated with the on-site photo information is reduced, making it possible to create an on-site survey report based on more accurate location information.

[0032] Furthermore, in the field survey support device 1 in this embodiment, the field survey information registration means 14 further creates and registers location map information showing on a map the absolute coordinates acquired by the coordinate acquisition means 12 when the first image was taken, thereby obtaining location map information showing on a map the absolute coordinates associated with field photo information consisting of multiple images, and making it possible to easily check the inspection points of the field photo information consisting of multiple images on the map.

[0033] In addition, in the field survey support device 1 of this embodiment, the field survey information registration means 14 further identifies and registers distance information of mileposts on the road route based on the position information acquired by the coordinate acquisition means 12 when the first image is taken, thereby obtaining field photo information consisting of a plurality of images associated with the mileposts on the road route, and making it possible to easily check the field photo information of the inspection location identified by the milepost. [Industrial Applicability]

[0034] The on-site inspection support device and program of the present invention are useful as a device and program for supporting on-site inspection of road structures such as road surfaces, slopes, bridges, tunnels, culverts, and accessories on roads such as expressways and general roads.
