The invention discloses a subway platform door obstacle detection and early warning system based on a machine vision technology. The system comprises cameras, cache equipment in communication connection with the cameras, a monitoring unit in communication connection with the cache equipment and the cameras, and an alarm device in communication connection with the monitoring unit. The two cameras are installed on mechanical structures arranged on the two sides of a subway platform door respectively, are away from the ground by a certain height and face a detected area of the subway platform door. The system uses a machine vision technique, has three-dimensional attributes, can judge key information, such as the occurrence time of the obstacle, the type and the occurrence position of the detection object in real time, can comprehensively evaluate whether the obstacle is dangerous or not, removes the dangerous obstacle or the behavior of the dangerous obstacle before the signal handover of the platform door and a train, and is superior to a conventional detection and early warning system in timeliness, reliability and safety.
本发明公开了一种基于机器视觉技术的地铁站台门障碍物探测预警系统,包括:摄像机,与摄像机通信连接的缓存设备,与缓存设备及摄像机通信连接的监控单元,以及与监控单元通信连接的报警装置;所述摄像机有两台,分别安装在地铁站台门两侧所设的机械结构上,且距离地面一定高度,并朝向地铁站台门的被探测区域。本发明系统,使用机器视觉技术,具有三维属性,能够实时判断探测对象障碍物发生的时间,所属的种类和发生的位置等关键信息,能够综合评价障碍物是否具有危险性,并将具有危险性的障碍物或其行为解除在站台门和列车信号交接之前,其时效性、可靠性和安全性优于传统的探测预警系统。
