Scene hyperscan misalignment

Post by NickD »

Hi

Has anyone else had problems with hyperscans not being correctly aligned? I have had issues with non-vertical pipes/cylindrical shapes where the hyperscans show up as ghosting. At first I thought this was due to vibration, as I was scanning live plant. However, the last project was done in the workshop (reverse engineering a vessel) with zero vibration. The vertical main cylindrical portion was fine, however, there are nozzles at odd angles and even after manual registration of 2 scans, it was clear that the hyperscans were not aligned at these nozzles. I had good registration using only the main scans, without the hyperscans. This leads me to think the software incorrectly registered the hyperscans with the main scans. See attached screen shots showing the problem. Nozzles are 4"diameter at about 45 degrees to the vertical.

Can you share out two of the scans you are having an issue or post overview to help identify the issue?
