基于超声波测距的多旋翼无人机避障算法

An Ultrasonic Ranging-based Algorithm for Obstacle Avoidance of Multi-rotor UVAs

利用超声波测距的方法,对旋翼无人机进行远程检测,测出障碍物的方向和位置。当障碍物的位置近于所设定的位置时,便激发出相应的触发信号,该触发信号导致障碍物图像被采集,然后通过对采集到的图像进行处理,得到障碍物的边界清晰的边缘,从而实现多旋翼无人机避障算法的设计。

Ultrasonic ranging was applied to a multi-rotor UAV to detect the direction and location of an obstacle in the study.A signal was to be activated when the obstacle was found to be close to a preset position,and then the signal will cause the image of the obstacle to be captured,which will be further treated for a clear profile.In this way,an algorithm on obstacle avoidance was designed for the multi-rotor UAVs.
