Re: Advice on first camera selection

I have used the Panasonic GH4 (rolling shutter and reduced resolution) with an HDMI capture device. I also have the PointGrey global shutter. I don't notice any real difference. With the PointGrey, I use the full resolution of the chip. At full resolution ( 2,048×1,536 ), I get faster scan time then...

Re: Advice on first camera selection

I am not specialist, but for sure the image circle is not wide enough.

Maybe if you stop-down, it will be ok. I would go with a lens at least made for the chip or larger, but not smaller.

Re: Advice on first camera selection

FYI, the PointGrey /Flir driver does NOT allow the use of two cameras with David / HP 3D. I think this is also true for Basler. If you decide to go that route, you should buy an IS camera. Or you could buy a Flir, but the second one will need to be from another brand. I am not sure it is worth the t...

Re: Camera/Projector Max Resolution and FPS

Speed is determined by many factors. Acquisition speed in David software is determined by Advanced setting -> Structuredlight -> Acquisition -> Maxpatternholdingtime Lower value as long as scan is good. Mine is set to 140 With one camera (resolution of 2,048×1,536), the scan time is around 5 seconds...

Re: Adjusrting camera aperture during scan session

No, never.

Once calibrated, I don't touch focus, angle or f-stop.

Re: David scanned by David - work in progress

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

Re: David scanned by David - work in progress

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 unti...
