[Outline of building inclination measurement process]
Here, the outline of the inclination measurement process of the building 1 using the measuring device 10 will be described with reference to FIGS. 1, 2, and 4 to 7.

[First example]
First, a first example of inclination measurement of the building 1 will be described with reference to FIGS. 1, 2, 4 and 5.
The measurer U wears the measuring device 10 shown in FIG. 2 on his head. Next, the measurer U views the first side 3A of the building 1 through the display 16 of the measuring device 10.

  Here, FIG. 4 shows an example of a screen displayed on the display 16. As shown in FIG. 4, the display 16 displays a horizontal surface 30 superimposed on the building 1. The horizontal plane 30 is a virtual object and penetrates the building 1 in the horizontal direction.

  Then, as shown in FIG. 4, the display 16 is drawn with a horizontal imaginary line 31 which is an intersecting line at which the horizontal surface 30 and the first side surface 3A of the building 1 intersect.

Here, for example, when the measurer U selects the first vertical joint 5A and the second vertical joint 5B of the first side surface 3A, the display 16 displays the horizontal imaginary line 31, the first vertical joint 5A, and the second vertical joint 5B. The first intersection 32A and the second intersection 32B, which are the intersections of
The selection of the first vertical joint 5A (or the second vertical joint 5B) may be specifically performed as follows.
For example, with the marker indicating the gaze direction of the measurer U displayed on the display 16 and the marker placed on the first vertical joint 5A (or the second vertical joint 5B), the thumb and forefinger of the hand of the measurer U are Perform an operation (hereinafter, click operation) to make contact from the released state. Thereby, the measuring apparatus 10 receives the operation of the measurer U and selects the first vertical joint 5A (or the second vertical joint 5B).

FIG. 5 is an enlarged view of a crossing point of the horizontal imaginary line 31, and the first vertical joint 5A and the second vertical joint 5B.
Further, in FIG. 5, an orthogonal line 34 orthogonal to the first longitudinal joint 5A and the second longitudinal joint 5B is shown. The orthogonal line 34 is shown for the purpose of explanation and may not necessarily be displayed on the display 16.
And the angle which the horizontal imaginary line 31 and the orthogonal line 34 make | form becomes inclination-angle (theta) (gradient) of the building 1 regarding 1st side 3A.

The measurement device 10 can obtain the measured distance (X) between the first intersection 32A and the second intersection 32B because the three-dimensional position of the building 1 can be identified.
Then, in the measuring device 10, based on the BIM data of the building 1, the distance (Y) between the first longitudinal joint 5A and the second longitudinal joint 5B, that is, the length of the orthogonal line 34 (the first intersection 32A and the third The distance of the intersection 33 is identified.

  Here, FIG. 6 shows an example of the screen displayed on the display 16. As shown in FIG. 6, the display 16 displays a vertical surface 40 superimposed on the building 1. The vertical surface 40 is a virtual object and penetrates the building 1 in the vertical direction.

  Then, as shown in FIG. 6, on the display 16, a vertical imaginary line 41 which is an intersection line where the vertical surface 40 and the first side surface 3A of the building 1 intersect is drawn.

Here, for example, when the measurer U selects the outer wall panel upper end 7 and the horizontal joint 4 of the first side surface 3A, the display 16 is an intersection of the vertical imaginary line 41 and the outer wall panel upper end 7 and the horizontal joint 4 A certain first intersection point 42A and a second intersection point 42B are set. The outer wall panel upper end portion 7 and the horizontal joint 4 are parallel portions extending in the horizontal direction.
The selection of the outer wall panel upper end 7 and the horizontal joint 4 may be performed in the same manner as the operation described in the first example.

Next, the process of measuring the inclination of the building 1 with respect to the first side 3A will be described with reference to FIG.
FIG. 7 is an enlarged view of the intersection of the vertical imaginary line 41 and the outer wall panel upper end 7 and the horizontal joint 4.
Further, in FIG. 7, an orthogonal line 44 orthogonal to the outer wall panel upper end portion 7 and the horizontal joint 4 is shown. In the example shown in FIG. 7, the orthogonal line 44 overlaps the right end of the first vertical joint 5A.
And the angle which the perpendicular | vertical imaginary line 41 and the orthogonal line 44 make | form becomes inclination-angle (theta) (gradient) of the building 1 regarding 1st side 3A.

The measurement device 10 can obtain the measured distance (X) between the first intersection point 42A and the second intersection point 42B because the three-dimensional position of the building 1 can be identified.
Then, in the measuring device 10, based on the BIM data of the building 1, the distance (Y) between the outer wall panel upper end 7 and the horizontal joint 4, that is, the length of the orthogonal line 44 (the first intersection 42A and the third intersection 43) Identify the distance)
Thereby, measuring device 10 can calculate inclination angle theta (gradient) of building 1 about the 1st side 3A.
Specifically, the inclination angle θ can be calculated by the following equation (1).
θ = arccos (Y / X) (1)

Then, the measuring apparatus 10 causes the tilt information display area 35 of the display 16 to display the calculated tilt angle θ.
The measurer U measures the inclination angle of the building 1 on each side by performing the above process on each side of the first side 3A, the second side 3B, the third side 3C, and the fourth side 3D of the building 1 it can.

Specifically, when the virtual line is the horizontal virtual line 31, the first vertical joint 5A and the second vertical joint 5B correspond to the above-mentioned "first reference portion and second reference portion", respectively.

  In addition, when the virtual line displayed on the display 16 by the virtual line display control unit 21 is the vertical virtual line 41, the building 1 is not inclined with “the first reference portion and the second reference portion” (that is, It shall extend horizontally when the slope is 0).

The “first reference unit and the second reference unit” may be selected based on the gaze direction of the measurer U and the operation of the measurer U, or may be designated in advance in the building 1.
Moreover, the measuring apparatus 10 may set "a 1st reference | standard part and a 2nd reference | standard part." In this case, for example, the processor 11 of the measuring apparatus 10 may set the pattern by extracting a specific pattern, for example, two parallel linear objects having a predetermined length or more from the captured image of the building 1 by the camera 14 .
In addition, even when the measurer U makes a selection, the one closest to the line of sight of the measurer U may be selected from among the plurality of linear objects extracted by the measuring device 10.

  Next, the measuring apparatus 10 acquires the distance (Y) between the first reference portion and the second reference portion based on the drawing data read in S101 (S108).

  Next, the measuring apparatus 10 calculates the inclination of the object plane of the building 1 based on the distance X and the distance Y (S109). The process of S109 is performed by the inclination calculating unit 24.

  Next, the measuring apparatus 10 outputs (displays) data of the inclination of the building 1 calculated in S109 to the display 16 (S110). The process of S110 is executed by the output unit 25.

  Further, the measuring apparatus 10 stores the inclination of the building 1 calculated in S109 in the storage device 12 in association with the target surface of the building 1 (S111).

Then, when there is an unprocessed target surface in the building 1 (S112: Yes), the measuring apparatus 10 returns to S102 and continues the processing.
On the other hand, when there is no unprocessed target surface in the building 1 (S112: No), the measuring apparatus 10 ends the process of measuring the inclination of the building 1.
