Yupeng Li · 2021
In the innovation and development of modern UAV technology, the actual research is mainly focused on rotorcraft UAV, and it meets the requirements of navigation control with too low speed. In this paper, the design and construction of a four-rotor UAV teaching experimental platform with photoelectric image processing as the core is the key point of this study. This experimental platform uses attitude sensor MPU 6050 and camera OV 7725, both of which are core airborne sensors, while ARM embedded system chip STM32F4 series belongs to the main control chip. R5F100 LEA series are auxiliary control chips. By using the optimized single loop PID control algorithm and accurately identifying the specific target material according to the photograph image processing algorithm, the automatic control experiment operation of the quadrotor UAV can be completed. The final experimental results show that the constructed airborne control system can effectively carry out flight control experiments, and can walk according to the set route, accurately deliver the expected set of substances, and search for specific substances. These functions are the basic contents of the practical operation of uav teaching experiment platform.
