Loss of details after fusion...

Postby AlbinKlein » Sat Jan 31, 2009 10:15 am

Hello, I am getting pretty good details when I scan with my new camera, Logitech pro 9000 BUT when I possion the scans I get a loss of details even if I possion it at 850 resolution....How can I avoid it?...When I do a simple fusion is good but is a bit rough and when I possion it then puff, very smooth and clean but with loss of detail...

Can you guys help me on this?

Hi,

- using Poisson fusion, I do not do any smoothing of the single scans in the scanning step. Leave them unsmoothed only interpolated.
- the fusion merges data (points of the pointcloud) near to each other. So if your aligned scans own "doubled skinned" areas in the needed overlapps, caused by unprecise alignment (or scanning), these areas will loose details. So if you notice a mesh not fitting precisly to the others, erase the overlapps after aligning or try (Global) Fine alignment several times...
- if there are fine details rise the fusion resolution (maybe 850 isn´t enough) and go for a coffee :D , it may last a while...

I don´t use any smoothing at all but seems my problem is with the overlapping scans..

Thanx
