摘　　要：SW-LiDAR系统在中国测绘科学院的指导帮助下,作为国产机载LiDAR的先行者日趋成熟,系统集成方面可以满足高精度轻小型,硬件和一些辅助软件也通过项目在不断创新和改革。安置角误差是机载激光雷达系统集成主要的误差来源。经过比较分析得出高程精度可达厘米级,充分显示出SW-LiDAR在高程模型领域的优势。本文采用地面检校场求解安置角的方法,通过安置角对特征地物点云造成的偏移来检校系统误差主要来源的安置角误差,结合山东省东营市采集的数据,并给出了具体的检校过程。With the help of the Chinese Academy of Surveying and mapping,the SW-LiDAR system is becoming mature as the pioneer of the domestic airborne LiDAR.The system integration can meet the requirements of high-precision,light and small,hardware and some auxiliary software are also constantly innovating and reforming through the project.The angle error is the main error source of the airborne laser radar system integration.Through comparison and analysis,the elevation precision can reach the centimeter level,which fully shows the advantages of SW-LiDAR in the field of elevation model.The ground calibration method for field placement angle,the main error sources of the calibration system to offset placement angle on the features of point cloud caused by the angle of arrangement,combined with the acquisition data of Shandong city in Dongying Province,and gives the specific process of calibration.
