Research on UAV Obstacle Avoidance Method Based on Virtual-real Combination Technology

At present, the research on the method of improving the obstacle avoidance ability of UAV mainly focuses on digital simulation and sensor-dependent technology. However, in complex and unpredictable environments, sensors may be affected by strong light, bad weather and other factors, resulting in ineffective obstacle avoidance and so on. Therefore, this paper proposes an obstacle avoidance method based on virtual-real combination technology, and constructs a virtual-real combination obstacle avoidance test platform, in the case of sensor failure, the test platform will control the UAV for obstacle avoidance operation. Therefore, the obstacle avoidance performance of UAV in complex environment can be greatly improved, and the purpose of safe and efficient flight can be realized.
