Development of Bridge Detection UAV Based on FPGA and Pixhawk

In order to solve the shortcomings of traditional UAV bridge detection, a special UAV for bridge detection was developed. This paper focus on the three problems of UAV reliability, flight positioning and data transmission. The improved Pixhawk flight controller is adopted in the UAV. The reliability problem is solved by using a combination of FPGA and sensor array, the positioning problem is solved by using a combination of RTK and 3D positioning, and the data transmission problem is solved by using a 4G transmission system. The UAV prototype tests show that the functions and reliability of the bridge detection UAV have achieved the intended design purpose and have high application value.
