摘　　要：在北京市焦化厂整体大范围三维激光扫描作业中,发现了大范围扫描作业与传统的小体量三维扫描作业方法之间不可避免的出现了各种新问题,扫描作业设计、数据拼接顺序、数据管理、整体坐标系转换等都需要进行更有效的规划和调整。本文主要提出一种新的大范围区域下多测站三维激光扫描数据的获取和管理方法,利用作业初期的分划区域和范围,采用分区布设控制和扫描作业,为后期的内业拼接及数据整体融合平差提供基础,以提高相应的点云整体精度。In the overall large-scale three-dimensional laser scanning operation of the Beijing Coking Plant,it was found that various new problems inevitably appeared between the large-scale scanning operation and the traditional small-volume three-dimensional scanning operation method.The scanning operation design,data splicing order,data management,overall coordinate system transformation,etc.all require more effective planning and adjustment.This paper mainly proposes a new method for acquiring and managing three-dimensional laser scanning data of multiple stations in a large area.Using the area and range of the initial stage of the operation,it adopts partition layout control and scanning operations for the later internal stitching and data.The overall fusion adjustment provides the basis to improve the overall accuracy of the corresponding point cloud.
