Unmanned aerial vehicle capable of being used for laser ranging

Abstract

The invention discloses an unmanned aerial vehicle capable of being used for laser ranging. The unmanned aerial vehicle comprises a fuselage and a device for laser ranging. The device for laser ranging comprises a shell fixed to the fuselage, a laser transmitter, a thrust assembly fixed to the laser transmitter, and a steering engine assembly connected with the thrust assembly in a sliding mode. A drive instruction is sent by a remote terminal to control the steering engine assembly so as to push the thrust assembly to slide, the thrust assembly is fixed to the laser transmitter, and finally the sliding thrust assembly drives the laser transmitter to move, so the relative distance between the laser transmitter and a target is precisely adjusted, the focusing function of laser beams is achieved, and the technical effect of precise measurement through the unmanned aerial vehicle is achieved.

Description

technical field [0001] The invention belongs to the technical field of laser distance measurement, in particular to an unmanned aerial vehicle which can be used for laser distance measurement. Background technique [0002] Laser distance measuring (laser distance measuring) uses a laser as a light source for distance measurement. Usually, the laser is used to accurately measure the distance of the target. When working, a laser is emitted to the target through the lens, and the laser beam reflected by the target is received by the photoelectric element. The timer measures the time from emission to reception of the laser beam, thereby calculating the distance from the observer distance to target. [0003] However, in the prior art, the laser beam projected to the target through the lens has a fixed focal length, which makes when the laser beam is projected on the target, due to the uncontrollability of the relative distance between the lens and the target, It is not necessar...

Problems solved by technology

[0003] However, in the prior art, the laser beam projected to the target through the lens has a fixed focal length, which makes when the laser beam is projected on the target, due to the uncontrollability of the relative distance between the lens and the target, It is not necessarily possible to obtain a clear projected image of the target during projection, and when the projected image of the target is unclear, it is easy to cause the measured distance of the target to be inaccurate; at the same time, the traditional laser ranging is applied to the UAV When, the same problem will also cause the measured distance of the target object to be inaccurate
