How to Densify Point Cloud After Segmentation for Better Meshing?

[ttm119]

Hello,

I am working on a project where I segment 3D point clouds and then try to generate a mesh from the segmented points. However, the number of points in the segmented data is very sparse, making it difficult to perform meshing effectively.

Is there a way to increase the number of points (densify the point cloud) after segmentation? Any advice or recommendations for tools, algorithms, or libraries would be greatly appreciated.

Thank you in advance for your help!

Hi, thanks for your interest. However, the number of points (3D Gaussians) is determined by the 3D-GS densification process automatically. A fact is that even if you have a very dense point cloud learned by 3D-GS, it does not help building high-quality mesh. You may refer to Gaussian Opacity Field and the relevant literature for more details.
