Generating a New Point Cloud with Regular Grid and Interpolated Gap Filling from Scanned Data

[Amin]

Hello everyone,
I hope you're all doing well.



I have a point cloud generated from a scanner that contains numerous points.
My goal is to create a new point cloud from this scanned data using a regular spatial grid, for example, at intervals of 0.1 by 0.1.
This new point cloud should retain the original shape and information from the initial scan.
Additionally, I would like to fill in any gaps by interpolating from the nearest points.
I attached a zip file which has a point cloud in .e57.

Best regards,
Amin

If the cloud was flat, I would have referenced the 'Rasterize tool' ... however since it's a 3D cloud, I'm not sure what to tell you. You may want to look at the 'MLS / upsampling' tool of the PCL plugin. You'll probably have to look at the documentation of the PCL library to understand if/how this works (this plugin is just a bridge to the PCL library).

Thank you for your reply. I've made several attempts to create an appropriate spatial grid but haven't achieved a satisfactory result.
