问题描述
我需要从密集点云中重建地形的表面网格.
I need to reconstruct a surface mesh of a terrain from a dense point cloud.
是否可以从 Meshlab 中的点云生成多边形网格?
Is it possible to generate polygonal meshes from point clouds in Meshlab?
推荐答案
是的！从点云生成网格的过程称为表面重建.
Yes you can!. The process of generating a mesh from a point cloud is called surface reconstruction.
meshlab中提供了几种表面重建方法.
There are several surface reconstruction methods avaliable in meshlab.

您可以在众多可用选项中选择一种.指导您一点:
There you can select one of the many choices avaliable. To guide you a little:
-
Delanuay三角剖分是最简单的方法之一，如果满足您的需要，你的表面并不复杂.
Delanuay Triangulation is one of the simplest one and might fit your needs if your surface is not complex.
表面重建:屏蔽泊松是最新技术，旨在用于重建复杂的表面.您可能需要在弹出对话框中加上一些参数，以便获得所需的结果.
Surface Reconstruction: Screened Poisson is state of the art and it's intended for reconstructing complex surfaces. You might need to tweek some parameters on the pop-up dialog in order to obtain the result you want.
