As shown in FIGS. 1 to 9, the anti-aircraft marker fixing jig according to the first embodiment of the present invention has an outer shell (main body 1) having a side surface 2 and a top surface 3. The side surface 2 has two A bolt insertion hole 4 is provided.
The upper surface 3 has a square shape in plan view, and the side surfaces 2 hang down from the four edges.
The bottom surface is open, and the overall shape of the main body 1 is a box-like body surrounded by side surfaces 2 and an upper surface 3 .

The main body 1 is made of a hard material such as resin, for example, and has a thickness of about 5 mm, a top side length of 100 to 110 mm, and a side surface height of 60 mm.
The material and shape are appropriately set according to the shape, size, etc. of the survey stake 5 and the anti-aircraft marker 6 to be applied.
The side surface 2 and the bolt insertion hole 4 are portions that function as attachment portions, and the upper surface 3 is a portion to which an anti-aircraft indicator 6 is attached as a supporting and fixing portion for the anti-aircraft indicator.

Two bolt insertion holes 4 are formed on the side surface 2 at intervals in the left-right direction.
The bolt insertion hole 4 is arranged slightly below the center in the vertical direction of the side surface.
A metal nut 7 (see FIG. 8) is embedded in the resin main body 1 and fixed to the bolt insertion hole 4 .
When the bolt 8 is screwed in from the side at a right angle, the tip of the bolt functions to hold down the side of the survey pile 5 inside.
When the main body 1 is attached to the surveying stake 5, the body 1 is set by overlapping the upper surface 3 of the main body on the upper head of the surveying stake 5 while aligning the positions of the exposure holes 9 and the nails 10, which will be described later. Then, while confirming the position of the survey pile 5, either one of the two bolt insertion holes 4 is selected and the bolt 8 is screwed. Since the bolt insertion holes 4 are formed at two locations with an interval in the lateral direction (horizontal direction), even if the surveying stake 5 is positioned at the corner of the main body 1, the bolt insertion hole 4 on the side where the surveying stake 5 is located can be used. By screwing bolts 8 through the holes 4, the surveying piles 5 inside are held down from all sides by the bolts 8, and the main body 1 is fixed.

A nail exposure hole 9 is formed in the center of the square upper surface 3 . Here, the center is the position where the diagonal lines from the four corners of the upper surface of the square intersect.
The exposure hole 9 has a short, upwardly projecting cylindrical shape, and the nail 10 passes through the cylinder to expose its head.
This nail 10 indicates a reference point indispensable for surveying a vast developed land or the like, and is attached so as to be aligned with the center of the anti-aircraft marker 6 .
When mounting the main body 1 , the position of the nail 10 is inserted into the exposure hole 9 for alignment, and the upper surface 3 is placed on the top surface of the surveying stake 5 .

The survey stake 5 to which the main body 1 is attached is a wooden stake with a square cross section of 45 mm on each side and a length of 450 mm to 600 mm, the upper part is colored red, the top is flat, and the lower part is driven into the ground. Therefore, it has a sharp shape.
A nail 10 representing a reference is further driven into the top of the surveying stake 5 installed on the ground. This nail is a reference portion that indicates accurate positional coordinate information, and the center of the anti-aircraft marker 6 is aligned with this nail 10 and attached.

Next, a surveying method using the anti-aircraft marker fixing jig according to the second embodiment will be described.
A survey pile 5 is installed at a reference point by ground site survey. The survey piles will be installed at multiple locations depending on the size and topography of the survey site.
After the surveying stake 5 is installed, a nail 10 indicating a more detailed reference portion is driven into the head. This nail is an accurate reference point for surveying.
Next, an anti-aircraft indicator fixing jig is put on the surveying stake 5, and the main body 1 is set by overlapping the upper surface 3 of the main body 1 with the top surface of the surveying stake 5 while aligning the positions of the exposure hole 9 and the nail 10. - 特許庁Then, one of the two bolt insertion holes 4 is selected while confirming the position of the pile, and the bolt 8 is screwed. Since the bolt insertion holes 4 are formed at two locations with an interval in the lateral direction (horizontal direction), even if the surveying stake 5 is positioned at the corner of the main body 1, the bolt insertion hole 4 on the side where the surveying stake 5 is located can be used. By screwing bolts 8 through the holes 4, the surveying piles 5 inside are held down from all sides by the bolts 8, and the main body 1 is fixed.

After fixing the main body 1 to the surveying stake 5, the peg 10 of the exposure hole 9 and the center of the anti-aircraft marker 6 are aligned and the anti-aircraft marker 6 is attached to the upper surface 3 of the main body. In the present application, since the supporting fixing portion is supported on the top of the surveying stake and fixed by the bolt 8, the anti-aircraft marker 6 can be securely supported and fixed in the horizontal direction.
The upper surface 3 of the main body and the anti-aircraft indicator 6 are fixed by a hook-and-loop fastener, double-sided tape, or other known detachable structure.

Photogrammetry is performed from the sky by a drone 11 (unmanned flying object) equipped with equipment (see FIG. 10).
Even if the flight position of the drone 11 causes distortion in the periphery, each of the anti-aircraft markers 6 has a unique identification pattern. data can be obtained.
In this embodiment, the drone 11 can be used for construction of dangerous places where workers cannot enter and large commercial facilities, and can fly thousands of survey data from the sky (30 m to 150 m or less) for about 15 minutes. As a result, it is possible to save labor for surveying work that has taken a long time until now.
In laser surveying, a laser is emitted from a laser device mounted on the drone 11, and accurate three-dimensional terrain data can be obtained by combining the laser reflected on the ground and the GPS position information of the aircraft.

Although the embodiments have been described above, the specific configuration of the present invention is not limited to the above-described embodiments, and the present invention includes design changes and the like within a range that does not depart from the gist of the invention.
For example, in the above embodiment, a square box-shaped anti-aircraft marker fixing jig was described, but the jig is not limited to this. Any configuration is included in the present invention.
In the above embodiment, two bolt insertion holes are provided, but the number and positions of the bolt insertion holes can be appropriately set depending on the size of the main body and the survey pile to be applied. Also, according to the shape of the main body and the size of the surveying pile, it is included in the present invention as long as the left and right spacing is such that the bolt can hold down the surveying pile wherever it is positioned within the main body.
