point cloud processing - black circle from scan location

Post by jramirez » Fri May 12, 2017 11:56 pm

Hi,

I have these crazy black circles from the scan location in my project point cloud. I created my project point cloud useing Homogenize point density and I also applied color balance. Can someone help me out and tell me how to get rid of these. Maybe I am not starting my processing correctly.

Thanks,

Jessica, when you visualize not the PPC, but the SPCs, are you still missing points at the scanner locations?

Did you tick the edge filter box when you first processed the scans? This filter removes alot of data from the ground and will reduce your overlap.

Yes I am missing the points at the scanner locations viewing SPCs.

And I'm not sure if I ticked the edge filter box or not. I do not use those settings very often.

Thanks for the tip about the edge filter box.

What version of Scene are you using and have you used the new Edge Artifact filter? this is an aggressive filter that could potentially remove good points.
