To solve the problem of low positioning accuracy of fixed-point delivery of logistics UAV, we proposed a solution for precise positioning of logistics UAV. In this scheme, the two-dimensional code image recognition was applied to the flight control system, and the position and three-dimensional coordinate model of the two-dimensional image in the air were established. CamShift tracking algorithm based on local features was used to guide UAV to fly and land so as to achieve precise landing at low altitude. The outdoor test results show that the tracking speed of the logistics flight control sys...
