利用LiDAR点云的真正射影像遮蔽检测

LiDAR Point Clouds Based Occlusion Detection of True-ortho Image

  • 摘要: 针对LiDAR系统真正射影像生成过程中由于高地物投影差产生的遮蔽问题,结合LiDAR点云数据提出了一种新的检测方法,将传统的基于格网的遮蔽区域检测转化为基于多尺度的TIN三角面片遮蔽检测。利用荆州市区获取的LiDAR数据对该方法与传统方法进行了比较,实验证明,该算法通过多重检测后忽略平坦地区,能够快速、准确地检测出遮挡区域。

     

    Abstract: A detailed study of occlusion detection of true-ortho image has been carried out in LiDAR system.Differing from traditional grid based method,an innovated multi-scale Tin based method was proposed.Some LiDAR data of ShaShi area has been adopted in the experiment.It has been found that this method can ignore the flat area and identify the occlusion exactly and quickly by multi detection.
