Japanese Patent Laying-Open No. 2003-288384 (FIG. 1)

One type of construction verification that has been implemented for a long time is a blackboard that contains explanatory information (construction name, shooting date, material name, drawings, etc.) regarding the content of the work being carried out in the verification target section. It has been practiced to lean on the verification target part and shoot with a camera so as to be in the photographic image frame together with the verification target part.
According to the conventional construction verification apparatus described above, it is possible to prepare a blackboard and write the explanation information, or to place the blackboard on the verification target part and copy it into a photograph as digital processing on the computer. The photo synthesizing means is provided, so that the efficiency of the photo shooting operation can be improved.
However, the construction photo book created in this way will be described by taking the situation of reinforcing bar arrangement as an example. The reinforcing bars that have been placed in the photo are recorded as a scene viewed from the camera installation position. On the other hand, the CAD reinforcing bar drawing is expressed by a plan view or a front view, for example. Therefore, it is difficult to recognize at a glance that the pitch, length, etc. of the reinforcing bars in the photograph are executed according to the CAD drawing.
Therefore, at the time of taking a picture, it was difficult to verify the construction, for example, whether the pitch of the reinforcing bars is as shown in the drawing.

  Accordingly, an object of the present invention is to provide a construction verification apparatus capable of solving the above-described problems and performing construction verification easily and accurately.

  The first characteristic configuration of the present invention is that the image information obtained by photographing the construction status of the construction verification target part in the construction and civil engineering fields, and the CAD information capable of three-dimensionally displaying the construction drawing of the verification target part are displayed on the same screen. When the judgment by the judgment means is passed, the judgment means for judging whether or not the construction status matches the construction drawing from the image information and the CAD information, There is a feature that recording means for digitally recording the image information in association with the corresponding CAD information is provided.

According to the first characteristic configuration of the present invention, the overlap display unit can display the image information and the CAD information in a state where the corresponding members appear to overlap each other on the same screen. In addition, the determination unit can automatically analyze, based on the image information and CAD information, whether the construction status matches the construction drawing, for example, using image processing technology. Therefore, verification that on-site construction is performed according to the CAD drawing can be automatically performed by automatic verification of the determination means, and more accurate verification is realized by visually checking the display screen. can do.
As a result, even if it is judged that the construction status does not match the drawing, the situation can be visually confirmed from the display screen, which can be used for redoing the construction, and finally a pass judgment can be obtained. can do.
On the other hand, since there is a recording means for digitally recording the image information and the corresponding CAD information associated with each other when the determination by the determination means is passed, Based on the digital record corresponding to the location, the image information and the CAD information can be displayed in an overlapping manner to reproduce the construction verification.
Therefore, for example, the reinforcement situation of reinforcing bars that cannot be easily confirmed after placing concrete, based on the digital image data taken at the time of construction and judged acceptable, later But you can prove it. As a result, the validity of the construction quality of the building can be verified consistently during construction and after construction.

  According to a second characteristic configuration of the present invention, the construction situation is a reinforcing bar arrangement situation at a construction stage, and a preferred photographing position where the number of reinforcing bars that can be photographed from the CAD information is maximized in photographing the construction situation. It is characterized in that there is provided a photographing position instruction means for automatically determining and indicating the determined photographing position.

According to the second characteristic configuration of the present invention, since the photographing position instruction means is provided, it is possible to instruct even without investigating the photographing position at the site and determining the photographing position where the number of reinforcing bars that can be photographed is maximum. You can capture the maximum amount of rebar in a single photo just by shooting from the selected shooting position. Accordingly, it is possible to speedily carry out the photography work from the optimum photographing position.
In addition, since the maximum number of rebars can be photographed from one shooting position, even if it is necessary to shoot from multiple directions in order to shoot all the reinforcing bars at the corresponding location, the shooting position and shooting at one location A shooting plan can be made so that the number of times is minimized.
Therefore, the photography work for verifying the reinforcing bar arrangement can be performed more efficiently.

  The third characteristic configuration of the present invention is to display the location information of the verification target part of the construction for performing the construction to be photographed on the day of photographing from the process table information prepared in advance, and photograph from the location information. It is characterized in that a shooting location instruction means for indicating the location is provided.

  According to the third characteristic configuration of the present invention, the location information of the verification target part that is being constructed on the day of all the verification target parts of the building is displayed on the screen by the photographing location instruction means, Since the shooting location is instructed, it is easy to make a shooting plan for the day, and it is possible to efficiently carry out the shooting operation by eliminating shooting and movement at a useless shooting position.
