Upsampling 3D point cloud using PCL

Question

I have a sparse point cloud of a 3D model. I need to populate the point cloud. In other words, I need to upsample the point cloud for surface reconstruction of the 3D point cloud.

I followed this link, but could not understand the method.

Is there an easy way to do that ?

Thanks in advance.

Answer 1

An alternative resource with some simpler code using the Point Cloud Library is available at the following link: http://pointclouds.org/documentation/tutorials/resampling.php

I would suggest starting there. Note that the code just calls an implementation of MLS in the Point Cloud Library. It will be up to you to play with parameters and investigate the code if necessary.
