Densify/interpolate points in cloud

Post by PablerasBCN »

Hello.
I woul like to increase the point number in the cloud. I've searched the forum with no luck. The closest cases I found was due to the need of filling holes after removing trees. So far the only way to densify the cloud I understand would be to mesh the cloud and extract vertices.

It is for visualization purposes. Not to have holes when the camera is nearby. If interpolated points where in a separate cloud I could camera clip per layer and use point size.

Is that correct?.

A suggestion would be to points generate triangular face with closest points and add a point in the center of triangle with interpolated color. Like for step 1. If 2 step. Use newly created poin and the vertex of the original triangle to create subtriangles and add point in center of each triangle. And so on.

Cheers

Indeed, CloudCompare doesn't deal with this kind of process. However the MLS tool of the qPCL plugin may be able to "densify" a cloud.

Of course there's also the option of creating a triangular mesh (with Delaunay or Poisson) and then sample points on the mesh (with a controlled density: Edit > Mesh > Sample points).
