Waves in scanns

Product Name: David SLS-3
Operating System: Microsoft Windows 10 (64-bit)

I'm having trouble with waves, slicing, patterns in my scans I have tried all the recommended fixes I have found. Any ideas? I'm using a new standard David SLS-3 with V5.1 software and a second David camera. I'm new to David and currently use photogrammetry and IR rangefinder systems to do my captures.

To solve the wave issue I have tried 3 different computers, 2 different projectors, tried all combinations of projector frequency, camera frame rates, camera exposure, have no problems with calibration.

 

The scans look mostly fine with the texture on this phenomenon is seems more pronounced on curved objects and sometimes at certain light levels.

 thanks, any help greatly appreciated

Re: Waves in scanns

Are you scanning in a dark room? If no, please try. Turn all lights off and avoid sunlight.

Re: Waves in scanns

Here in some posts there were mentioned that there are no lines in scans with the original david/hp hardware. It is not so at all: look to the picture from the HP 3d Scan product page:3DscannerFastScanning_tcm245_2355247_tcm245_2355248_tcm245-2355247.jpg

I've marked lines here.
