基于机载激光雷达数据快速建立多分辨率不规则三角网

Quick constructing multiresolution triangulated irregular network based on airborne LIDAR data

文中运用虚拟三角网将机载激光雷达数据进行虚拟分割,并与逐点插入法相结合,实现了快速构建多分辨率不规则三角网,既节省了建网的时间,又保留了数据的原始信息,使地面信息达到了更好的表达。

This paper combines virtual triangulation network and point by point interpolation for building multi-resolution triangular irregular network.It can save the time of building TIN and retain the original information of the data and express ground information better.
