Sorry, I don't know how the scanner above works. I guess, because of the colours red, green and yellow that the different channels of a colour camera are somehow used.
The arm with the camera rotates under the platform where the woman is standing on.
I have just made SL scans of a low shoe with the turn around scanner. The shoe was stationary and the rig was rotated for 8 positions à about 45°. Both laces were free-hanging. I hadn't made additional scans from top and bottom. And on the suggestion of Mattia I have mounted a wheel from an old office chair at the end of the horizontal arm. Yes, it's a bit shorter shaking now.
Some additional infos:
Video projector Acer K11, Modified WebCam Logitech C600 at 800x600@15fps. Single scans: No smoothing, 2x interpolation.
Only the horizontal stripes were used for scanning, means about 6sec for each scan. "Convex" calibration corner.
DAVID 3 Beta09.
Settings:Frequency=8, Phase Shifts=5, Pattern Holding Time=300, Fusion=650
Only the alignment of the single scans was made with DAVID 2.6.3 because it is more familiar for me.
