摘要
本项目研究机载激光雷达系统辅助地形图绘制,该系统由激光雷达系统、DGPS/IMU惯性导航系统和高分辨率相机[1]组成,可获得激光数据、POS数据和数码数据,通过DEM、DOM的制作,提取等高线,采集地物数据,人工调绘隐蔽区,最后修饰整改,提交成果。测得的地形图精度高,测绘时间短,通过验证,成果满足规范标准。
In this project,airborne liDAR system is used to assist topographic mapping.The system is composed of lidar system,DGPS(Differential Global Positioning System)/IMU(Inertial measurement uni)inertial navigation system and high-resolution camera[1].Laser data,POS(point of sale)data and digital data can be obtained.Through the production of DEM(Digital Elevation Model)and DOM(Digital Orthophoto Map),contour lines can be extracted,surface feature data can be collected,hidden areas can be manually drawn,modified and rectified,and results can be submitted.The accuracy of the topographic map is high and the mapping time is short.Through verification,the results meet the standard.
