Now I found it!!!! :oops:

Sometimes I don't see the wood for all of its trees.
In the next days I will test it by SLS. But you didn't mention if your SLS was fine with a mjpg compression.

Thanks!

Normally a later version is mainly better than the older one. Also for DAVID.

If you like to exactly know the improvement over a former version you can find this info in the latest DAVID folder in the file 'ChangeLog.txt'.

I'm kind of a newbee, too. But I sure will have a look if I can help.
Can you upload your scans anywhere? Maybe I can see if they align.

And your problem are the stripes on the scanned calibration panel?
If you search the forum you will see that there might be many reasons. I think most likely is missing sync between camera shutter and projector refresh rate. On which refresh rate is your projector working?

I have less stripes if I do a combined setup, camera vertical AND horizontal from the projector. And, very often I see stripes on the calib panel but not on the scanned object.

On the other hand, if you do that as a profession, you should consider upgrading from a simple unmodified webcam. Go and buy the David cam!
