Description

Technical Field

[0001] The utility model relates to the technical field of geographical surveying and mapping, in particular to an aerial photography device for geographical surveying and mapping. Background Art

[0002] Surveying and mapping refers to the measurement and collection of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface, and the selection of existing feature points and lines on the ground to obtain graphics and position information reflecting the current status of the ground through measurement methods.

[0003] A search of publication number CN216269887U discloses an aerial photography device for geographic surveying and mapping, including a drone body, a fixing rod vertically installed at the bottom end of the drone body, an arc-shaped buffer rod provided at the bottom end of the fixing rod, a spring rod vertically installed at the bottom end of the arc-shaped buffer rod, and a plurality of spring rods are installed.

[0004] The comparative document discloses an aerial photography device for geographic surveying and mapping. Although it uses a fixed rod, an arc-shaped buffer rod, a spring rod and a universal wheel to provide a buffer when the drone lands, the dust raised during the drone's takeoff often adheres to the camera lens, affecting normal shooting during surveying and mapping.

[0005] To this end, we propose an aerial photography device for geographic surveying and mapping. Utility Model Content
