Tangentially related question for any of you GIS people who might be lurking in this thread:
Can anyone recommend me a method of meshing LIDAR point clouds? The sparseness of the data on building walls & other near-vertical surfaces combined with a lack of point normals leads to degenerate solutions with all the common approaches (poisson/ball pivot/vcg in meshlab) not to mention extremely slow perf. Tree canopies and overhanging parapets make a simple heightmap approach less-than desirable (though ultimately acceptable if I can't find anything better). I'm trying to turn 90 billion lidar points into maybe 30-50 million triangles, hopefully without spending months developing a custom pipeline.
- shrinks99 1y agoI think Meshroom can use LIDAR data as an input now? I used it years ago for photogrammetry and camera tracking for some VFX work and it's an incredibly solid suite of open source tools for these types of tasks.

It combines airborne LiDAR and building footprints, it's OS (https://github.com/3DBAG https://github.com/3DBAG) with the reconstruction pipeline here: https://github.com/3DBAG/roofer https://github.com/3DBAG/roofer.
