I tired to take 4 scan of human face. after each scan, I delete noisy and wavy edge and area of each scan. the auto alignment did a good jobs for all scans. later at fusion state, I use pairwise fine registration with texture enabled to align each scan again. And finally I fuse them together at resolution 1000. attached is the final output.
However, I got edge of each scan at the final fusion model as highlighted in attachment. And it takes me very long to process auto alignment (1-2 minutes). Has anyone got similar problem? and how do you solve it? I understand that it may caused by breathing movement of human. I tried to hold the breath when scanning. if this is the case, how do you minimize it? thank you!
My camera and sls-2 setting for each scan
exposure: 60, brightness: 255, pattern: quality, orientation: both, auto grab texture, smooth average: 20, smooth median: 20 and auto alignment to previous scan.
