The invention discloses an anti-collision protection system for an unmanned aerial vehicle. According to the unmanned aerial vehicle anti-collision system, the ultrasonic anti-collision module achieves autonomous anti-collision through the ultrasonic technology, the corresponding anti-collision algorithm is provided, the safety of the unmanned aerial vehicle is greatly improved, meanwhile, the system design has the advantages of being low in cost, light in weight, small in size, high in precision and the like, safety guarantee is provided for application of the unmanned aerial vehicle in the complex environment, and the application range is wide. The method has important engineering significance, and meanwhile, an obstacle depth detection method based on binocular vision is arranged in the visual detection obstacle avoidance module. The visual detection obstacle avoidance module calculates depth information of an object through camera calibration, stereo correction, stereo matching, parameters obtained through calibration and a parallax result obtained through stereo matching, so that a better obstacle avoidance function of the unmanned aerial vehicle is achieved, and the unmanned aerial vehicle is enabled to have a better obstacle avoidance effect in a use process through cooperation with the ultrasonic anti-collision module. The system has a stronger obstacle avoidance protection safety function, and the overall safety of the system is improved.
