Unmanned aerial vehicle for topographic surveying and mapping

Abstract

The invention relates to an unmanned aerial vehicle for topographic surveying and mapping, which belongs to the technical field of surveying and mapping devices. The unmanned aerial vehicle comprisesan unmanned aerial vehicle body, a multi-angle detection mechanism, a buffer soft landing mechanism, a protection mechanism, a mounting frame and a carrying platform. Four rotating arms distributed ina matrix mode are arranged on the edge of the top of the unmanned aerial vehicle body. A propeller is arranged at the top end of each rotating arm. The protection mechanism comprises a driving assembly and four propeller protection assemblies arranged at the top of the carrying platform, and each propeller protection assembly comprises a protection cover, a buffer assembly, a mounting base and aconnecting plate. According to the invention, the horizontal angle and the pitching angle of the detection head can be adjusted through the multi-angle detection mechanism; the rugged terrain can be conveniently surveyed and mapped by the detection head, all the propellers can be protected through the protection mechanism, collision between the propellers and birds is avoided, and the situation that normal use of the propellers is affected due to the fact that the propellers directly collide with the outside can be avoided.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping devices, in particular to an unmanned aerial vehicle for terrain surveying and mapping. Background technique [0002] Topographic surveying and mapping refers to the operation of surveying and mapping topographic maps, that is, the work of measuring the projected positions and elevations of objects and terrain on the earth's surface on the horizontal plane, reducing them to a certain scale, and drawing them into topographic maps with symbols and notes. The surveying and mapping of the map basically adopts the method of aerial photogrammetry, and the aerial photo is mainly used for indoor mapping. With the continuous development of science and technology, advanced digital aerial photogrammetry technology has been widely used in the surveying and mapping geographic information industry, and my country's topographic surveying and mapping industry has also made great progress in the fiel...
