一种机载激光雷达点云非均匀化的解决方法

A Solution for the Nonuniformity of Airborne Lidar Point Cloud Data

笔者首先阐述了激光雷达的工作原理和机载激光雷达目标位置的计算方法,然后针对目标点出现连续相同楔形镜旋转角度的问题,提出了一种机载激光雷达点云非均匀化的解决方法.该方法不仅能降低激光雷达设备采集数据时的算法复杂度,在提高采集数据存储效率的同时,还能还原真实采集数据状态.还原后的点云呈均匀分布,构建的三维场景的轮廓更加清晰、真实。

The author first explained the working principle of lidar and the calculation method of the airborne lidar target position,and then proposed a solution to the non-uniformity of the airborne lidar point cloud for the problem that the target point has the same continuous wedge mirror rotation angle.This method can not only reduce the complexity of the algorithm when the lidar equipment collects data,but also restore the real collected data state while improving the storage efficiency of the collected data.The restored point cloud is evenly distributed,and the contour of the constructed 3D scene is clearer and more realistic.
