Re: David scanned by David - work in progress

@ Micr0, Sorry, I didn't see your last question previously. Yes, that's correct. I set the FPS to 59.846 The shutter to: 15.10ms The PointGrey software has an "absolute mode" for the input which is 1 by 1 incremental. I set FPS to 60, then switch to absolute mode and fine tune until the l...

Re: David scanned by David - work in progress

going to through your first post again, 34 scans for a rather small statue is too many i believe, of course you set the quality check at 0.6 which is higher than normal and ignores much of the scanned data in hope of a higher quality scan. did you have time to scan a larger object? I'd try my luck w...

Re: Alignment problems

It's hard to judge from a screenshot with that side of panel on an angle. Questions: What are the angles between camera and projector (horizontal and vertical) Are you scanning only in horizontal or both ? What version of David ? What camera ? How is your panel made ? Jeff 23UX236, LG PF1500W, my s...

Re: David scanned by David - work in progress

Yes, my parts are mostly long and the width is much smaller than lenght.
Do you align your scans using contact pair or manual sequence?
I can only get usable results if i do contact pair.

Re: David scanned by David - work in progress

Impressive results, however 30cm is a rather small part. would you try on a larger object, maybe 1m and above, to see how things go?

Re: Low distortion Lens for 23ux236

FWIW I wonder about the need for a very good lens on the camera side (?) Stepping down the lens will use the best part of the lens and increase depth of field ( as long as the stepping is within reason). I find that a precise calibration board, a correct angle between camera and projector, good f-s...

Re: Alignment problems

im getting elipses away from the center, instead of circular target points on the calibration panel. its on the side thats not facing the camera directly. the other side facing the camera looks ok.

What do you suggest? to eliminate this?

Re: Alignment problems

I have tried but when i enter a number, it completly deletes the entire scan. I tried large and small numbers. What's the unit of that number? Micro, You do large scans too as far as i remember. Without a large calibration panel, do you get good alignments using your regular ~200mm calibration panel...

Re: Alignment problems

One possible approach is to select all the scans, then right click and select "shrink border" (or whatever it is called. I am not in front of my computer). You can repeat as many times as you like as long as you preserve overlapping areas. Save you project before each step in case you nee...
