摘　　要：全野外数据采集在大比例尺地形测绘中外业投入人力成本和工作强度较高,倾斜摄影技术对复杂地形和裸露程度要求较高,针对现行方法存在的不足和缺陷,提出基于三维激光扫描技术的大比例尺地形图测绘。通过对测区三维激光扫描,采集测区地形点云数据,通过对点云数据去噪、拼接、建模,生成大比例尺地形图。试验证明:本方法测绘误差接近1 mm,可以实现对大比例尺地形图精准测绘。All-field data acquisition in large-scale topographic mapping requires higher labor cost and work intensity and oblique photographic technology requires higher complexity and exposure.Aiming at the shortcomings and defects of current methods,a large-scale topographic mapping based on Three-Dimensional Laser Scanning Technology is proposed.Through the threedimensional laser scanning for the survey areas,the topographic point cloud data of the survey areas is collected and the large-scale topographic map is generated by denoising,stitching and modeling the point cloud data.The experiment shows that the error of this method is close to 1 mm and the accurate mapping of large-scale topographic map can be achieved by it.
