摘　　要：结合新型国产Lidar系统SSW扫描车在丹东地区的农村地籍测量生产实际,详细讨论了其外业推扫过程中的控制点设置等相关问题,完善了车载扫描系统用于地籍测量时的控制点的作用、布设、使用及测量方案等环节,重点讨论了控制点参与点云解算来提高点云匹配精度的基本流程和利用现有特征道路附属标牌作为控制点的方法,为该技术进一步走向市场奠定基础。Based on the application practice in Dandong area using SSW scanner equipped with a new type of domestic Lidar system,problems of control point setting for field push-broom are discussed in detail. The function,layout,application and measurement scheme of vehicle scanning system for cadastral survey have been improved. The basic process of point cloud calculation by using control points to improve point cloud matching accuracy and the method of using existing characteristic road attachment signs as control points are specifically discussed in depth,which has laid a foundation for further development of this technology to the market.
