[0002] With economic development and the improvement of industry technology level, traditional topographic surveying and mapping operations often use on-site investigation and mapping methods in infrastructure or photovoltaic power generation projects with complex terrain and landforms and ultra-large-scale projects. However, these methods have the disadvantages of personnel being unable to get involved, long investigation time, high work intensity, and low work efficiency. In addition, some complex areas are dangerous. Therefore, current staff use drones in the field of surveying and mapping.

[0003] At present, the mapping device of the oblique photography of the UAV performs mapping during the flight of the UAV. However, during the flight, the aerial mapping lens will often collide with insects and other impurities in the air, resulting in the surface of the mapping lens being blocked, affecting the mapping effect. Moreover, when the UAV returns, the insects or impurities on the lens surface have dried and attached, making it inconvenient to clean, thereby reducing the service life of the mapping lens.

[0019] Example: like Figure 1 - Figure 7 As shown, this embodiment proposes a surveying and mapping auxiliary device based on oblique photography of a drone, comprising a drone body 1, a connecting bracket 2, a gimbal frame 3 and a surveying and mapping machine 4, wherein the connecting bracket 2 is arranged on the lower surface of the drone body 1, the gimbal frame 3 is connected to the connecting bracket 2, and the surveying and mapping machine 4 is installed in the gimbal frame 3 through a limiter component; wherein a safety frame 5 is arranged around the surface of the surveying and mapping lens of the surveying and mapping machine 4, and a transparent protective plate is arranged in the safety frame 5 through a clamping component; Press the two limit plugs 12 to drive the two moving blocks 11 closer to each other, and insert the limit plugs 12 into the limit slots 15 opened on the two side walls of the bayonet 6. As the first spring 10 deforms, it will elastically react to the moving blocks 11, so that the two moving blocks 11 move away from each other, drive the two limit plugs 12 to move away from each other, and insert them into the limit slots 15 to fix the installation frame and the surveying and mapping machine 4, thereby improving the installation convenience of the surveying and mapping machine 4; insert the transparent protective plate into the protective frame 7 through the slot 16, and as the transparent protective plate in the strip slot 18 moves away from each other, the installation frame and the surveying and mapping machine 4 are fixed, thereby improving the installation convenience of the surveying and mapping machine 4; insert the transparent protective plate into the protective frame 7 through the slot 16, and as the transparent protective plate in the strip slot 18 moves away from each other, the installation frame and the surveying and mapping machine 4 are fixed, and the installation convenience of the surveying and mapping machine 4 is improved; The plate squeezes the upper and lower limit blocks 20, so that the two limit blocks 20 squeeze the second spring 19, and the second spring 19 is deformed, so that the two limit blocks 20 clamp and fix the transparent protective plate. During the surveying and mapping process, insects and other impurities in the air will only collide with the surface of the transparent protective plate, which improves the safety and service life of the lens of the surveying and mapping machine 4. After the surveying and mapping is completed, the lever 22 is moved to move the two limit blocks 20 away from each other, and the fixation of the transparent protective plate is cancelled, and the transparent protective plate can be removed for cleaning. The overall structure is simple and easy to use, and there is no need to clean the lens.

When the surveying is completed, the two levers 22 are pushed to drive the two limit blocks 20 away from each other, so that the limit blocks 20 are away from the transparent protective plate, and the fixation of the transparent protective plate is cancelled. The transparent protective plate can be removed for cleaning, thereby ensuring the cleanliness of the lens, eliminating the need to clean the lens, and improving the service life of the lens.
