Colorization TLS Point Cloud
« on: February 22, 2021, 09:27:22 PM »
Hi,

I imported e57 point cloud form laser scanning and aligned with photos. The cloud has 23 mln points.
When I colorize cloud from photos only small part get colors. What could be a problem?



Regards,
Kuba

Hello Kuba,

Do the imported E57 files contain the point normals?

Can you confirm, if the point normals are correct, when you are navigating the dense cloud in the Model view mode?

Indeed the problem was in point normals. I recomputed and inverted normals with CloudCompare and colorization went well.
Thanks!
