I am David Laser Scanner lover. But i also need to know if someone out here experimented with Flexscan ? I want the opinion about accuracy and surface smoothness obtained with Flexscan. No matter what i do i never get perfectly smooth results from David.

yea I tried flexscan but totally failed :D just because 3 pairs of point grey cameras bought for that program are not supported!! so David is the best :)

I don't think that FlexScan will give better quality data than DAVID for a few reasons. If hardware is the same for comparison, there is little that the software will help for better data quality. This is for what I call 'naked' scan where no smoothing or averaging is applied. The one thing that makes all non-contact scanners expensive when you start to get into high fidelity and good tight resolution is optics. The lenses make the quality and matching to good camera is equally important. 2 cameras will not improve quality. The only thing that 2 cameras will do is reduce the effects of triangulation and being able to 'see' around a corner or into trenches where 1 camera cannot see or where projector cannot project.

that's the point, you need less aligning and get less error, so scan is more precise and spend less time. Also David got one little disadvantage comparing to high cost scanning systems- you wont get scan in 0.5sec as in 3dMD with 4 cameras and 2 infrared projectors for 180 degree model.

Count me in as interested in the flat panel, dual camera calibration and scanning. :D

Is it about you or David?
There are many scans of yours in the user gallery. Aren't they smooth?
Nearly all of HAL's scans are perfectly smooth. I didn't understand your comment. Are you telling that even the smoothest scan we think isn't perfectly smooth? Are we deceiving ourselves or what :?:

Version 3.9 is out for a while, V4 in on the way, will it be with single calibration board as someone mentioned? Or this will be an extreme surprise for everybody?

Hey guys!

How is it going with the dual System and the flat calibration? I saw some maybe dangerouse developments and Software implementation in the Internet (like http://3dlsx.de/) - I mean it would be time to get a new lead in the front...

Alex :)
