Man-machine safety protection system and safety protection method

The invention provides a man-machine safety protection system and a safety protection method. A common camera is adopted and arranged at the top end of a robot, whether an object enters the detectionrange specified by a user is judged through a foreground extraction method by filtering out pixels of a robot body, if a moving object appears, the robot is slowed down or stopped, and safety of the robot and operators is ensured. The common RGB camera is adopted, and the cost is low; and the camera does not need to be calibrated, the detection range can be specified according to the user requirements, maintenance is convenient, configuration is flexible, and efficiency is high. 本发明提供种人机安全防护系统及安全防护方法，采用的普通的摄像头，将摄像头置于机器人顶端，通过过滤掉机器人本体的像素点，利用前景提取的方法判断是否有物体进入用户规定的检测范围，如果出现移动的物体即使机器人减速或者停止，保证机器人和操作者的安全。本发明采用普通RGB摄像头，成本低廉；无需标定摄像头并且可以根据用户需求规定检测范围，维护方便，配置灵活，效率较高。
