Design of Obstacle Avoidance System for Agricultural Four Rotor Aircraft Based on Machine Vision and Wireless Location

In order to improve the efficiency and safety of agricultural and forestry plant protection in the area with complex terrain, the four rotor aircraft is applied to the agricultural production process. In order to improve the autonomous navigation level of the four rotor aircraft, the machine vision technology and wireless positioning technology are introduced into the design of the aircraft control system. Through the combination of the two positioning methods, it effectively improves the navigation accuracy of the aircraft. Software simulation is used to test the obstacle avoidance system.During the test, a variety of obstacles are set up.According to the form of feedback system and no feedback system, the obstacle avoidance behavior of the aircraft is tested respectively.From the test results, the aircraft can avoid obstacles more accurately and complete autonomous navigation after using the feedback system.
