The objective of the invention is to provide an unmanned aerial vehicle for distance measurement and obstacle avoidance by using a grating for solving the problem of complex operation of a grating processor, and the unmanned aerial vehicle comprises a grating emitter, a camera, a processor, a distance measurement mirror, a protection shell and an unmanned aerial vehicle. The grating emitter is fixedly connected to the front end of the protective shell, the camera is electrically connected with the processor, a through hole is formed in the front end of the protective shell, a light sensing part of the camera is arranged in the through hole and faces the flight direction of the unmanned aerial vehicle, the distance measuring mirror is a plane lens, and an annular light transmitting part and a light blocking part are arranged on the surface of the plane lens. The light transmitting part and the light blocking part sequentially and alternately extend outwards from the center of the distance measuring mirror until the distance measuring mirror is fully distributed, the distance measuring mirror is arranged right in front of the camera light sensing part and is connected with the protective shell, and the protective shell is fixedly connected to the unmanned aerial vehicle. According to the invention, the calculation amount is greatly saved, the response speed of the processor is well improved, an instruction can be sent out more quickly when obstacle avoidance is needed, and the flight safety of the unmanned aerial vehicle is further improved.

    本发明的目的是针对光栅处理器运算复杂的问题,提供一种利用光栅测距避障的无人机,包括:光栅发射器、摄像头、处理器、测距镜、保护壳和无人机;光栅发射器固定连接于保护壳前端,摄像头和处理器电连接,保护壳前端开有通孔,摄像头感光部设置在所述通孔内且朝向无人机的飞行方向,测距镜为一平面透镜且其表面设置有环状的透光部和挡光部,所述透光部和挡光部从测距镜中心依次交替式向外延伸直至布满整个测距镜,测距镜设置在摄像头感光部的正前方且与保护壳连接,保护壳固定连接于无人机。大大节省了运算量,处理器的响应速度得到了很好的提升,在需要避障时,能够更为迅速地发出指令,进一步提升了无人机飞行的安全性。
