Meshlab 中点云的网格 [英] Mesh from point clouds in Meshlab

问题描述

我需要从密集的点云重建地形的表面网格.

I need to reconstruct a surface mesh of a terrain from a dense point cloud.

是否可以在 Meshlab 中从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，你可以！.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 中有多种表面重建方法可用.

There are several surface reconstruction methods avaliable in meshlab.

转到过滤器 ->网格化、简化和重构

您可以在那里选择众多可用选项之一.给你一点指导:

There you can select one of the many choices avaliable. To guide you a little:

• Delanuay Triangulation 是最简单的三角测量之一，如果你的表面并不复杂.

• Delanuay Triangulation is one of the simplest one and might fit your needs if your surface is not complex.

表面重建:筛选泊松是最先进的技术，用于重建复杂的表面.您可能需要在弹出对话框中调整一些参数以获得您想要的结果.

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.
