由于植被表面和地表的几何与物理特性的不同，激光脉冲反射后获取的光强值表现出明显的差异，因此光强信息可以作为分割地面和植被激光脚点的特征参数之一，基于此提出了一种基于光强信息统计量空分割LiDAR点云的方法，该方法无需设置任何参数，实施方便，操作简单，特别适用于森林地区植被脚点的提取。

For the geometric and physical characteristics of vegetation and ground ,the reflected intensity from the topographic surfaces has different values .So a new LiDAR segmentation method based on statis‐tics analysis of intensity has been proposed in this paper .The method is simple and effective ,without set‐ting any parameters beforehand .Results show that the method can efficiently separate tree points from ground points in a forested area .
