Abstract：To enable autonomous path flight of the quadrotor UAV,this paper proposes on autono-mous flight design based on optical flow sensor and laser rangefinder is proposed without GPS signal.The method is to build a set of indoor and outdoor quadrotor UAV flight platform,with Pixhawk4 flight control board as the core,Raspberry PI as the airborne computer,Beixing TFmini PLUS laser ranging radar for height control,optical flow sensor LC-302 for optical flow positioning.The software is designed on the basis of laser height fixing,optical flow fixing and airborne computer code control.Through experimental verification,the proposed method can complete the preset flight path task and realize the autonomous path flight of the quadrotor UAV.
