How to remove low sampling surface in poisson reconstruction?

cleitia
This post was updated on .
Poisson Reconstruction reference site (http://www.cs.jhu.edu/~misha/Code/PoissonRecon/Version9.01/) provides "Surface Trimmer".
So It can remove low sampled surfaces from poisson reconstruction.

Means of surface trim is as follows.
 - Poisson Surface Reconstruction tries to create a watertight mesh, i.e. it creates a lot of "excess" surface, closes holes etc. Sometimes this is desired, in that case set this value to 0. Increasing this value will cut away more surface.


But in PCL, There is not surface trimmer API and I can't get density value of iso-surface from poisson result.


I want to know these..

- Is there a way to do surface trim in PCL?
- or Can you tell me how to calculate the density value of iso-surface from mesh in poisson surface..


Please let me know.
Thanks.

I am rather new to PCL, and never done this myself, but I think you can use the original point cloud to estimate the point density using OctreePointCloudDensity class.

After setting the tree, you can query the vertices of your mesh with OctreePointCloudDensity's getVoxelDensityAtPoint() method.
