UAV path recognition and tracking based on image

This paper firstly analyzes and establishes the motion model of the quadrotor UAV, and then designs the image recognition and control system scheme for the path tracking task. In the image recognition part, the path information is obtained and the desired position signal is obtained by the steps of image optimization, Hough transformation, determining flight direction, identifying the drop-point area, and the PID control is used in the control system part. From the simulation results and 3D visualization module, it can be seen that the UAV can complete the straight-line flight, curve flight, and landing action well, and the image recognition and flight control scheme designed in this paper has good performance.
