Track plate fine adjustment method based on point cloud data
The invention provides a track board fine adjustment method based on point cloud data. The track board fine adjustment method comprises the steps that a laser scanner generates 3D point cloud data and transmits the 3D point cloud data to a control center; the control center carries out denoising through an optimization algorithm; the control center identifies two optical prism control points in front of and behind the track board to be laid and the measuring equipment through an optimization algorithm, calculates relative coordinates of the optical prism control points, and obtains a coordinate system transformation matrix by combining absolute coordinates of the optical prism control points in a world coordinate system; according to the design coordinates and the actual coordinates of the four points on the plane on the track plate in the absolute coordinate system, the fine adjustment amount needed by each point is calculated; and the displacement needing to be finely adjusted is sent to the corresponding intelligent fine adjustment equipment for fine adjustment. Real-time data of the fine adjustment amount of the track plate can be obtained only through one three-dimensional laser scanner, earlier-stage investment of equipment and manpower is reduced, the high-precision fine adjustment amount of the track plate is obtained through calculation with an optimization algorithm, the accuracy of fine adjustment is guaranteed, and the construction efficiency of fine adjustment of the track plate is improved.
本发明提供一种基于点云数据的轨道板精调方法,包括:激光扫描仪生成3D点云数据并传递至控制中心;控制中心通过优化算法进行去噪;控制中心通过优化算法识别待铺设轨道板和测量设备前后各2个光学棱镜控制点,计算光学棱镜控制点的相对坐标,结合光学棱镜控制点在世界坐标系中的绝对坐标得到坐标系转换矩阵;根据轨道板上平面四点在绝对坐标系中的设计坐标和实际坐标计算出每一个点需要精调量;将需要精调的位移量发送至对应智能精调设备进行精调。本发明只需一台三维激光扫描仪便可得到轨道板精调量的实时数据,减少了设备和人工的前期投入,采用优化算法计算得到高精度的轨道板精调量,保证了精调的准确性,提高了轨道板精调的施工效率。
