[Outline of pile position inspection using pile position inspection device 10]
Next, the outline of the pile position inspection using the pile position inspection device 10 according to the present embodiment will be described with reference to FIGS. 3 to 6.

FIG. 3 shows an outline of the construction site 30 in which the pile 33 was driven by the pile driver 31.
FIG. 4 schematically shows a top view of the construction site 30.
As shown in FIGS. 3 and 4, a benchmark 32 as a reference for the position is arranged at the construction site 30, and a code label 32A is affixed to the upper surface of the benchmark 32.
The code label 32A may be, for example, a sticker on which a two-dimensional code is printed, and is affixed to a predetermined position on the benchmark 32.
For example, the identification information (building ID) of the building to be constructed and the position information of the benchmark 32 (or the code label 32A) are encoded in the two-dimensional code.

Next, the inspector of the pile position looks at the construction site 30 through the display 16 of the pile position inspection device 10 with the pile position inspection device 10 attached.
First, the pile position inspection device 10 obtains coordinate information of each part of the construction site 30 in the real space based on the three-dimensional shape data of the construction site 30 taken by the camera 14.
Next, the pile position inspection device 10 reads the code label 32A of the benchmark 32 by the camera 14 and obtains the building ID encoded by the code label 32A and the position information in the coordinate space of the building model of the benchmark 32. The data of the building model may be obtained by downloading from the building data management server 50 based on the building ID.

Then, the pile position inspection device 10 aligns the real space with the coordinate space of the building model based on the correspondence between the coordinates of the benchmark 32 in the real space and the benchmark model 42 in the building model.

Here, FIG. 5 shows a display example of the display 16 visually viewed by the inspector.

The pile model 43 includes a pile model center 43A and a virtual line 43B drawn at predetermined distances from the pile model center 43A.
For example, the above "predetermined distance" may be a fixed value, or may be set according to the distance between the pile position inspection device 10 and the pile 33. That is, as the pile position inspection device 10 approaches the pile 33, the "predetermined distance" may become smaller so that more detailed position deviation can be determined.

Further, as shown in FIG. 6, the display 16 displays information on the positional deviation between the pile center 33A of the pile 33 and the pile model center 43A of the pile model 43. As a result, the inspector can recognize how much the construction position of the pile 33 deviates from the design value.

Further, when the pile position inspection device 10 receives a predetermined operation from the inspector, the pile position inspection device 10 records the inspection image 45 in which the pile model 43 is superimposed on the pile 33 as inspection data. Then, the pile position inspection device 10 may transmit the inspection data of the pile 33 to the inspection data management server 60 after the inspection of the pile 33 is completed.

Further, the pile position inspection device 10 realizes the pile position inspection method according to the present invention by executing the process based on the above program.
Hereinafter, the details of the functions of the above-mentioned parts provided in the pile position inspection device 10 will be described.

[Explanation of building data acquisition unit 20]
The building data acquisition unit 20 acquires three-dimensional data of the building to be constructed at the construction site. The process executed by the building data acquisition unit 20 is the building data acquisition step.

"Three-dimensional data of a building" includes the building itself, piles for ground improvement, and a benchmark model. The benchmark may be an object with a fixed position provided at the construction site. For example, the three-dimensional data of the building may be the data of the BIM model.

The building data acquisition unit 20 is mainly realized by the processor 11 of the pile position inspection device 10, the storage device 12, the communication interface 13, and the camera 14.
Specifically, the processor 11 transmits the building identification information (building ID) to the building data management server 50 via the communication interface 13. In response to this, the building data management server 50 reads the building 3D data (BIM data) stored in association with the building ID from the building database 52, and transmits the building 3D data to the pile position inspection device 10. do.
The processor 11 of the pile position inspection device 10 receives the three-dimensional data of the building from the building data management server 50 via the communication interface 13.
The building identification information may be input from the inspector, or the code label 32A attached to the benchmark 32 may be read by the camera 14 to obtain the building ID encoded by the code label 32A.

[Explanation of the alignment unit 21]
The alignment unit 21 aligns the pile with the pile model in the three-dimensional data of the building. The process executed by the alignment unit 21 is the alignment step.
The alignment unit 21 is mainly realized by a processor 11, a storage device 12, a communication interface 13, a camera 14, and a line-of-sight direction detection device 15.

A "pile" is a steel pipe driven into a construction site 30 for ground improvement of the construction site 30. It is assumed that an identification number (pile number) is assigned to the pile.
The "pile model" is a virtual object having a one-to-one correspondence with a pile in the three-dimensional data of a building. The pile model may have the same size (diameter, length) as the corresponding pile.

By aligning the position of the benchmark 32 of the construction site 30 with the benchmark model 42 of the building model, the alignment unit 21 aligns the real space of the construction site 30 with the virtual space of the building model (coordinate mapping). ) Is executed.
The "benchmark" is a reference point of a position at a construction site 30, and is an object whose position does not change.
The "benchmark model" is a virtual object that has a one-to-one correspondence with the benchmark. The benchmark model may be the same size as the corresponding benchmark.

For example, the alignment unit 21 displays the building model on the display 16 and accepts the position adjustment from the inspector so that the orientation and position of the benchmark model 42 of the building model match the benchmark 32 of the construction site 30. Therefore, the above alignment may be performed.

Further, for example, the alignment unit 21 aligns the construction site 30 with the three-dimensional data (building model) of the building based on the position information encoded by the code label 32A affixed to the benchmark 32 of the construction site 30. May be done.
The "code label" is a label on which a one-dimensional code or a two-dimensional code is printed. For example, the building ID and the position information of the benchmark are encoded in the "code label".
Then, the camera 14 of the pile position inspection device 10 reads the code label 32A, so that the processor 11 of the pile position inspection device 10 obtains the building ID encoded by the code label 32A and the position information of the benchmark 32.
Specifically, the position information of the benchmark 32 encoded by the code label 32A may be that the relative positions from the code label 32A to the four corners of the benchmark 32 are recorded, for example, assuming that the benchmark 32 is a rectangle. .. By doing so, the position of the benchmark 32 in the real space can be specified by reading the information of the code label 32A.
As a result, the processor 11 of the pile position inspection device 10 can align the coordinates of the real space of the construction site 30 with the coordinates of the virtual space of the building model.

[Explanation of display control unit 22]
The display control unit 22 superimposes and displays the pile model 43 on the pile 33 displayed on the display 16 as the display unit. The process executed by the display control unit 22 is the display control step.
The display control unit 22 is mainly realized by the processor 11 of the pile position inspection device 10, the storage device 12, the communication interface 13, the camera 14, and the line-of-sight direction detection device 15.

The display control unit 22 generates a rendered image of the building model in the virtual space based on the line-of-sight direction in the real space of the inspector detected by the line-of-sight direction detection device 15, and displays it on the display 16.
That is, the display control unit 22 causes the display 16 to display the pile model 43 in the virtual space so as to overlap the pile 33 in the real space displayed on the display 16.

Further, the display control unit 22 causes the display 16 to display the amount of misalignment between the pile 33 and the pile model 43.
The "positional deviation amount" is data indicating a difference in distance or coordinates between the pile center 33A of the pile 33 and the pile model center 43A of the pile model 43.
The data shown in the misalignment amount display area 44 in FIG. 6 corresponds to an example of the above "misalignment amount".
Specifically, the display control unit 22 calculates the above-mentioned misalignment amount from the respective coordinate positions of the pile center 33A and the pile model center 43A, and displays the misalignment amount data on the display 16.

Further, the display control unit 22 causes the display 16 to display the virtual line 43B at predetermined distances from the center of the pile model 43.
The "predetermined distance" may be, for example, a unit length (1 mm, 1 cm, etc.) or an arbitrary length.
The "virtual line" is a virtual line displayed on the upper surface of the pile model 43. For example, a concentric circle having a radius that is an integral multiple of a predetermined distance centered on the pile model center 43A of the pile model 43 corresponds to an example of the above "virtual line".
Further, for example, a grid line of a predetermined distance (predetermined interval) passing through the center 43A of the pile model of the pile model 43 corresponds to an example of the above "virtual line".
In this way, the display control unit 22 makes it easier for the inspector to grasp the amount of misalignment between the pile 33 and the pile model 43 by displaying the virtual line 43B indicating the distance from the pile model center 43A on the display 16. ..

[Explanation of inspection image recording unit 23]
The inspection image recording unit 23 records an inspection image in which the pile model 43 is superimposed on the pile 33 displayed on the display 16 in association with the identification information of the pile 33.
The inspection image recording unit 23 is mainly realized by the processor 11 of the pile position inspection device 10, the storage device 12, the communication interface 13, and the camera 14.

The "pile identification information" is information that uniquely identifies each pile 33. For example, the pile number corresponds to an example of the above-mentioned "pile identification information".
The "inspection image" corresponds to a screenshot on the display 16 in which the pile 33 and the pile model 43 are superimposed. That is, the inspection image 45 shown in FIG. 6 corresponds to an example of the above “inspection image”.

Specifically, the inspection image recording unit 23 stores the inspection result of the pile in the inspection data table T. For example, as shown in FIG. 8, the inspection data table T stores the building ID, the pile number, the deviation amount, the inspection image, the inspection date and time, and the inspector's information in association with each other.

Further, the pile position inspection device 10 may transmit the inspection data table T recorded by the inspection image recording unit 23 to the inspection data management server 60 and store it in the inspection database 62.

[Flow of processing by pile position inspection device 10]
Next, the flow of processing executed by the pile position inspection device 10 will be described with reference to FIG. 9.
As shown in FIG. 9, the pile position inspection device 10 photographs the code label 32A of the benchmark 32 provided at the construction site 30 by the camera 14 (S101). Then, the pile position inspection device 10 acquires the data (building ID, position information of the benchmark 32) encoded by the code label 32A.

Next, the pile position inspection device 10 downloads the data (building data) of the building model (BIM) of the building ID from the building data management server 50 (S102).

Next, the pile position inspection device 10 aligns the position of the benchmark model 42 of the building model with the benchmark 32 provided at the construction site 30, so that the virtual space of the building model and the real space of the construction site 30 are aligned. Coordinates are associated (S103).

Next, the pile position inspection device 10 superimposes the pile model 43 on the pile 33 and displays it on the display 16 (S104).
For example, the screens shown in FIGS. 5 and 6 are examples of screens displayed on the display 16.

Here, the pile position inspection device 10 targets the pile 33 determined to be in front of the line of sight by the line-of-sight direction detection device 15, and measures the positional deviation of the pile 33 to be inspected from the pile model 43 ( S105).
Then, the pile position inspection device 10 displays the measured amount of the misalignment on the display 16 as shown in the misalignment amount display area 44 of FIG. 6, for example.

Next, the pile position inspection device 10 records an inspection image 45 in which the pile 33 and the pile model 43 are superimposed (S106) according to the operation of the inspector, and stores the inspection data including the inspection image 45 in the storage device 12. (S107). For example, one record in the inspection data table T corresponds to the above inspection data.

Next, if there is another pile 33 to be inspected (S108: Yes), the process returns to S105, and if there is no other pile 33 to be inspected (S108: No), the pile position inspection device 10 is up to that point. The inspection data recorded in the above is transmitted to the inspection data management server 60 (S109), and the process is terminated.
In the above flow, the pile position inspection device 10 may transmit the inspection data of the pile 33 to the inspection data management server 60 every time the pile 33 is inspected in S107.
