在利用三维激光扫描技术进行逆向建模过程中，点云数据的质量直接决定着模型的质量，而多片点云数据拼接处理的优劣又影响着点云数据的质量。通过对多片点云拼接原理的研究，提出了不贴反光片的“三点法”拼接处理方法，该方法只需找出多测站扫描的点云数据中的三个公共点可进行点云数据处理，解决了以往的“三点法”处理手段下建筑物必须贴反光片的难题。利用该方法首次对大型钢桁架桥梁的点云数据拼接处理，拼接完成了该大桥的完整点云数据模型，其精度满足逆向建模的精度要求。
Research on Processing Technique of Multiple Point Cloud Data Registration
In the process of reverse modeling by using 3D laser scanning technology ,the quality of the models is directly determined by that of point cloud data . However , the quality of point cloud data is affected by the splicing quality of multiple point cloud data .Through the study of the theory of multiple point cloud registration ,the“three-point”splicing method without patches is proposed here .This method only needs to find out the three common points of point cloud data scanning by multi-stations to go on the point cloud data processing ,which could solve the previous processing problem that with the way of “three point method” ,the buildings must be stuck with reflectors .For the first time ,through using the method to process the point cloud data registration of a large steel truss bridge ,a full point cloud data model of the bridge is completed with splicing ,and its precision could satisfy the accuracy requirement of reverse modeling .
