Dear support team,
I scanned a wood block with 14.5*29.5*57.5 mm . this is the image of the scans. could you please tell me what is wrong with this alignment?
It appears that most of your scans are all taken only showing two sides of the block. Unfortunately this doesn't provide a lot of overlap between scans and the alignment algorithm is producing the results that you are seeing.
It may help to scan the block from an angle such that the camera/projector combination can see at least 3 faces of the block at a time. Then you can align subsequent scans to the scan that has the 3 faces, and continue the alignment process from there.
