摘要
机载LiDAR系统中存在多种误差,本文主要对系统中最大的系统误差源—安置角误差进行了介绍,并对该项误差提出了一种不需要布设地面控制点就可以进行检校的方法,并给出了检校的具体流程,最后就通过地物点云的匹配吻合程度以及点云坐标相对精度来验证检校的结果。
There are many effors in airborne LiDAR systerm. The paper mainly introduced one of the most offending effors-the boresight misalignment and put forward a calibration method without control points. Then it gave the work flow. Finally the effect of the calibration work was proved by the matching level between the features and point cloud, and the relative coordinate accuracy of the point cloud.
