LAS Point cloud support #39

Closed fwilliams closed 11 months ago

fwilliams commented 1 year ago

I've been asked a few times about this -- it would be nice to support LAS inputs at some point:

heiwang1997 commented 1 year ago

I've gone through the documentation that you sent. Does LAS offer us (meta) information other than just xyz (and sensor positions)?

fwilliams commented 1 year ago

The docs for laspy are better: https://laspy.readthedocs.io/en/latest/intro.html

heiwang1997 commented 1 year ago

Thanks!! So I think we could just store the meta information (such as projection) along with the reconstructed mesh? What change do we need in NKSR's codebase to support LAS? It's just a new data reader other than open3d right?

So, if I've the mobile mapping scan data in .las tiles what should I do? because the input seems to need the normals and points as separate inputs.

You could refer to the newest example on las file under the folder examples/
