[0002] Photogrammetry is a technique that uses a combination of cameras and films to measure and obtain the shape, size and spatial position of the target object. Its main task is to produce topographic maps of various scales, establish a topographic database, and provide basic spatial data for geographic information systems, land information systems and various projects. This technology is not only applicable to the field of geography, but also to many fields such as industry, architecture, biology, medicine, archaeology, etc. Aerial photogrammetry usually needs to be shot at multiple locations and multiple angles to obtain accurate topographic maps;

[0003] After searching, a Chinese patent with the announcement number of CN215725919U discloses a highly safe aerial remote sensing photogrammetric instrument. The patent records that by setting a support mechanism, when the landing frame contacts the ground, it will move upward against the piston tube, and then the piston tube will move upward against the lifting plate, and the lifting plate will move upward against the push rod, and then the push rod will move upward against the sliding frame. At the same time, due to the limiting effect of the connecting rod, the fixed block, the first fixed plate and the second fixed plate will be driven to move toward the middle, and the second spring will be compressed. In this way, the photogrammetric instrument body can be further clamped and fixed when it lands, and the photogrammetric instrument body can be driven to move upward, so as to prevent the bottom of the photogrammetric instrument body from being damaged.

The blades 4 correspond to each other, and the blade protection cover 11 is sleeved on the outside of the propeller blade 4. A threaded sleeve 5 is fixedly connected to the top of the fuselage 1, and a threaded hole 2 9 is opened inside the threaded sleeve 5. The outer walls of the blade protection covers 11 on both sides are fixedly connected with connecting rods 10. The other end of the connecting rod 10 is fixedly connected to a connecting ring 6. A threaded hole 1 8 is opened inside the connecting ring 6. At the same time, the threaded hole 1 8 corresponds to the threaded hole 2 9. A threaded column 7 is arranged on the outside of the connecting ring 6. At the same time, the threaded column 7 is threadedly connected in the threaded hole 1 8 and the threaded hole 2 9.

[0027] Position the blade protection cover 11 on the propeller blades 4 around the fuselage 1, then move the connecting ring 6 to the threaded sleeve 5 on the fuselage 1, align the threaded hole 2 9 with the threaded hole 1 8, pass the connecting ring 6 through the threaded column 7, and rotate the threaded column 7. As the threaded column 7 rotates, the connecting ring 6 is gradually tightened and firmly fixed on the fuselage 1. The blade protection cover 11 and the protective net 12 protect the propeller blades 4, prevent the fuselage 1 from being damaged by environmental factors during flight, play a role in protecting the propeller blades 4, and drive the propeller blades 4 to rotate and rise by starting the motor 3.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a mounting frame 13 is fixedly connected to the bottom of the fuselage 1, a photogrammeter 24 is arranged inside the mounting frame 13, a connecting assembly is arranged between the photogrammeter 24 and the mounting frame 13, the connecting assembly includes a pair of springs 19, a pair of connecting balls 20 and a pair of inner holes 21, and the connecting ball 20 is fixedly connected to one end of the spring 19, and the connecting ball 20 corresponds to the inner hole 21, and the connecting ball 20 is slidably connected in the inner hole 21, and the threaded rod 14 is threadedly connected to both sides of the mounting frame 13, and the other end of the threaded rod 14 is fixed A clamping plate 15 is connected, and a slider 17 is fixedly connected to the bottom wall of the clamping plate 15.

[0029] Install the photogrammeter 24 on the mounting frame 13. First, align the inner cavity 22 of the fixing column 23 at the bottom of the photogrammeter 24 with the bottom column 18 and insert it. When the bottom column 18 slides into the fixing column 23, the springs 19 on both sides of the bottom column 18 will elastically bounce the connecting ball 20 into the inner hole 21 to achieve positioning support. Then, rotate the threaded rods 14 on both sides.

After installing the blade protection cover 11, it is necessary to take a camera. The measuring instrument 24 is installed on the mounting frame 13. At this time, the inner cavity 22 of the fixing column 23 at the bottom of the photogrammetric measuring instrument 24 is aligned with the bottom column 18 and inserted into it. When the bottom column 18 slides into the fixing column 23, the elastic action of the springs 19 on both sides of the bottom column 18 will bounce the connecting ball 20 into the inner hole 21 for positioning support. At this time, the threaded rods 14 on both sides are rotated, and the clamping plate 15 is driven to move inward under the rotation of the threaded rods 14. At the same time, the clamping plate 15 is limited in the sliding groove 16 by the slider 17.
