| 摘 要： | 论述利用机载激光扫描系统(LiDAR)获得的激光点云和光学影像制正射影像的方法.以GPS和惯性导航单元提供的外方位元素结合激光点云作为地面参考,对光学影像进行空中三角测量,将LiDAR点云获得的数字表面模型经由滤波处理获得DEM,最后经过纠正算法获得正射影像.

| Abstract: | A method for producing digital orthophoto was discussed in the paper,using laser point cloud and optical image obtained from LiDAR system.Optical image was oriented by aerial triangulation,according to exterior orientation elements provided by GPS and inertial navigation system,and controled points collecting from laser point cloud data.DSM gained from LiDAR laser point cloud was filtered to get DEM.Orthophoto was produced through image rectification with the DEM,after image orientation. |
