Extract Rail from Laser Scan

[mbmiller34]

Any clever ideas on how to extract the rail from a laser scan data set?

I'd prefer the CL of rail if possible hah

By training a classifier dedicated to it? (as it's very linear and peculiar). Of course it depends on how dense the point clouds are.

Don't hesitate to share a sample cloud with me if you want me to try something (admin@cloudcompare.org).
