摘　　要：通过架站式三维激光扫描、无人机倾斜摄影测量与无人机机载LiDAR扫描三种新型测量方法获取同一区域内建筑的点云数据以及三维模型绘制该区域内建筑的平面图。以全站仪及RTK获取的建筑特征点作为参考,分别对三种方法获得的平面图进行差异统计,综合对比分析三种方法各自优缺点。The point cloud data of buildings and the planimetric map of the buildings in the same area were obtained by three new surveying methods:stationary 3D laser scanning,drone-based oblique photogrammetry,and drone-based LiDAR scanning.The building characteristic points obtained by the total station and RTK were used as references,and the differences between the planimetric maps obtained by the three methods were statistically analyzed(including planimetric and elevation results).The advantages and disadvantages of the three methods were comprehensively compared and analyzed to complete the feasibility analysis of using airborne LiDAR for building completion surveying.
