! Unfortunately here I can still achieve good results
Thanks Sven and Simon for your effort. Now I have less noise but the 3D mesh is still deformed (the deformation happens in the first tests, too).
I've tried again to calibrate the camera (49 mm) and the projectorwith both orientations.
But the result is distorted and the waves are there (less than first, but are there).
I've tried to calibrate the projector with only horizontal patterns (orientation vertical) and the calibration have some problems: sometimes the application crash, sometimes need long second to be calculated, and the quality sine is this:
All works bad as in the firsts tests. I'm using the BY8 video mode as suggested, with the projector above the camera, with high holding time (450), with a good angle, with good exposure settings (look the image down).
In an other discussion about grey values of the patterns, Gunter ask if my patterns are like his patterns. No, I can see in the camera view a grey smooth pattern like showed by Simon.
I fell my self so stupid! Like I am on my first steps with 3D scanning he he
p.s.: when I scan, not all the lines and fringes in the patterns are visible in the camera, because projector focusing need more distance from the object. So, something like 1/6, 1/7 of the height of the projection is cutted out. David need to see all the fringes? Could be this one of the reason for my problem?
