convert lidar point cloud data to polygon mesh

Recommended Posts

Hello,

I'v been struggling for quite a while with this. Does anyone know if there is a way to convert a lidar point cloud data to polygon mesh?

I have tried the particle fluid surface but It is taking for ever, not sure if I should keep waiting.

I've seen these beautiful images (all made with Lidar data) and would like to reach the same level of details.

All the best !

Chris

Try Alicevision. You must install Game Development Toolset first.
It's a free open source photogrametry plug-in developped by mikros image (As a French guy, you've got to know them :)

Don't try it, but having to do some meshing sometime ago, I don't find ideal solution.
Better results I get was from : vdbfromparticle-> vdbreshape->vdbsmooth->vdbconvert.
I wasn't aware of the Alice solution.

If you try it, let us know if it works well, I'm interested.

On a rather low resolution grid you could transfer the point clouds height coordinates with the nearpoint()-function.

To interpolate heights smoothly while making the grid flow exactly through the points, try this:
