Your settings are nearly identical to mine, except that I use YUY2 & Disabled (adjusted within David).

All other settings are adjusted using FlyCapture before.

1) The "Quality check & Outlier removal must be adjusted to your setup (scale size, power of projector, etc...). Start low and increase until you have enough good information to build a full model by overlapping scans without holes.

2) in Flycapture, (while David is projecting a pattern !) , zoom with the mouse and fine tune fps and shutter until most stable image using absolute values. First FPS, then shutter

My procedure is for a global shutter/ mono camera !!!

3) What is your f-stop setting ?

4) Don't use gain if possible.

5) Practice on neutral item to start (simple item painted light mate grey).

Good luck

Your bad alignment is a problem. I can't help much.

The problem is:

Camera lens
AND/OR
Projector settings
AND/OR
Projector lens
AND/OR
Precision of calibration panel
AND/OR
Angle between camera and projector if out of usual range

Set all Your white balance values for Red,green, blue to a single value. Your problem with Sine wave fluctuations and dotted picture will be solved.
