The invention relates to the technical field of rail transit, and discloses a safety monitoring method and system for a metro platform screen door. The method comprises the steps that the current motion state of the shielding door is detected, and when the current motion state is a closed operation state, point cloud data and image data around a door body are obtained; preprocessing the point cloud data to obtain first point cloud data; performing fusion processing on the first point cloud data and the image data to obtain door body three-dimensional data; and identifying and analyzing the three-dimensional data of the door body, detecting whether foreign matters exist in the door crack, if so, identifying and positioning the foreign matters, sending out a foreign matter alarm signal, and triggering the stop or reverse opening control of the vehicle door, so that the precision, adaptability and accuracy of safety monitoring are improved, and false alarms are reduced.

    本申请涉及轨道交通技术领域,公开了用于地铁屏蔽门的安全监测方法及系统。方法包括:检测屏蔽门的当前运动状态,当前运动状态为关闭运行状态时,获取门体周围的点云数据和图像数据;对点云数据进行预处理,获取第一点云数据;对第一点云数据和图像数据进行融合处理,获取门体三维数据;对门体三维数据进行识别分析,检测门缝是否有异物存在,若有,对异物进行识别和定位,发出异物报警信号,并触发车门停止或反向开启控制,本申请提高了安全监测的精度、适应性和准确率,减少误报。
