The invention belongs to the technical field of metro contact rail detection, and particularly relates to a metro contact rail rapid detection method and system.The detection method comprises the following steps that 1, a contact rail automatic detection device carrying a 3D camera is used for continuously and dynamically scanning a metro contact rail, and each frame of data of the 3D camera is taken out; combining Z-axis mileage sensor data of the contact rail automatic detection device to form a contact rail three-dimensional point cloud; 2, filtering point clouds of a lower contact type third rail, an upper contact type third rail and a return rail to remove invalid interference data, then carrying out feature multi-data cooperative training, and constructing unified point cloud features of a contact rail insulation support, an expansion joint and an end elbow; 3, when the contact rail automatic detection device moves for measurement, the contact rail surface, the insulation support, the expansion joint and the end elbow are judged in real time according to the point cloud features of the insulation support, the expansion joint and the end elbow of the contact rail, and the conduction height and pull-out measurement values of the components are calculated.

    本发明属于地铁接触轨检测技术领域,具体涉及一种地铁接触轨的快速检测方法和系统,检测方法包括以下步骤:步骤1:使用搭载3D相机的接触轨自动检测装置持续动态扫描地铁接触轨、取出3D相机每帧数据,结合接触轨自动检测装置的Z轴里程传感器数据,构成接触轨三维点云;步骤2:对下接触式第三轨、上接触第三轨、回流轨的点云进行滤波去除无效干扰数据后进行特征多数据协同训练,构建统一的接触轨绝缘支架、膨胀接头和端部弯头的点云特征;步骤3:接触轨自动检测装置移动测量时,用接触轨的绝缘支架、膨胀接头和端部弯头点云特征,实时判断接触轨轨面、绝缘支架、膨胀接头和端部弯头,计算出这些部件的导高、拉出测量值。
