摘要
目前,激光雷达点云的三维重建已经应用到很多领域,然而,激光雷达数据处理的自动化水平仍旧不是很高,应用激光雷达点云反射强度增进其自动化处理水平的方法仍在研究中。针对激光雷达点云反射强度受到入射角度的影响,从而影响数据处理自动化的问题,本文设计了两种不同对象激光入射角度与点云反射强度的实验,通过实验得出了实验条件下激光入射角度与点云反射强度之间的变化关系和数学模型,该模型可以用于激光反射强度的纠正,对于激光雷达点云应用的自动化处理具有非常重要的现实意义。
At present,the three- dimensional reconstruction of LIDAR point cloud has been applied to many fields. However,laser radar data processing automation level is still not high,and the method based on LIDAR point cloud reflection intensity enhance the automation processing level is still in the study. For the LIDAR point cloud reflection intensity influence by the of incident angle,thus affecting the problem of the automatic processing of data,this paper designs two different experiments about laser incident angle and point cloud reflection intensity. Through the experiment obtained variation relationship and mathematical model between the laser incident angle and point cloud reflection intensity. The model can be used to correct the intensity of laser reflection,for the automation of LIDAR point cloud application processing has a very important practical significance.
