[pdal] Hello Intro

[Karl Keller]

Thanks Andrew – looks like registration is their specialty.  Thanks for the hint.

ICP for 20M points is likely to take a really, really long time. You will probably have to do something else. You're only getting out a single transformation anyway. Perhaps you should look at the various methods provided by Open3D:

Hello PDAL community members.  Not sure how to get started so I’ll tell you about my interest in PDAL.

I’m using PDAL with the aim of building pipelines for various LIDAR processing workflows.  As a first step, I’ve been trying to use ICP registration without a lot of luck.  I’ve spent time following PJHartzell’s work on this to try and get a leg up.  If anyone has guidance in fast ways to automatically register relatively dense clouds in the 20M point range, I would be grateful.  Right now, I use sampling before registration to get a transform (quickly) and apply it to the full cloud.  Unfortunately, I’m not achieving < 300 mm accuracy and have yet to get convergence.

Looking forward to interacting with this group.
