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.

    本发明公开了一种无人机防撞保护系统。本发明中,超声波防撞模块使用超声波技术实现了自主防撞,并提出了相应的防撞算法,大大提高了无人机的安全性,同时,该系统设计具有成本低、重量轻、体积小、精度高等特点,为无人机在复杂环境中的应用提供了安全保障,具有重要的工程意义,同时视觉检测避障模块的内部设置有基于双目视觉的障碍物深度检测方法。视觉检测避障模块通过摄像机标定、立体校正、立体匹配,通过标定获得的参数和立体匹配得到的视差结果计算出物体的深度信息,从而实现了更好的无人机避障功能,配合超声波防撞模块,使得该无人机在使用过程,具备了更强的避障保护安全功能,提高了系统整体安全性。
