Some days later I will play with it more deeply...
Assembled the 3D-scanner at home.:)
The first play with it. Noisy enough, but it is the FIRST try in a hurry, it is too late already, I need to sleep and I have too many other things to do... So, I did not played with settings and hardware tunings... Just have calibrated quickly what is assembled, and scanned the first thing that I got next to me. Now just posting these first results and go to sleep.

Yep!steveps3 wrote:you have made your own 3D scanner?
I think I know what for fat-stripes noise is at bottom of this scanned box (that goes diagonal the box) - it is just my mistake, not the scanner quality, it is likely the reflection from the glossy cover of the book on which this box was. So, the real quality of scan is at top of the box, where this parasite reflection did not fall.
But now I know that it is needed to have the scanned thing on the black cloth.
If I knew it from the beginning, I think this box would have had equally good quality around all its surface. So, the next scan I think will have already ideal surface, and will be absolutely ready for using by my 3D-wife in its beloved Blender.
Perhaps later I will post some photos... Just had no time yesterday to do the photos, then write the big description... Some later I will do it.Daniel wrote:How did you make it?
It is easy to do. The most difficult thing was to assemble the precise calibrating panels for that scanner, not the scanner itself.
was it this one?

the software is free hardware is laser pointer and webcam
tried playing with that, but didn't have any of those laser pointers..

I guess Jim Star has built something to control the laser movement. Maybe a Arduino board with motor !?
Yes, and no.
DAVID is not free. It has trial version with cutted functionality, but full version costs 329 euro. Moreover, I very do not like its licensing policy, so I'm still thinking about buy some other soft (e.g. FlexScan3D) or write my own. In the first variant they bind the license to one computer, not to one workplace as all others do ("computer" concept nowadays is washed out to the ton of little parts, so just LOL, where ends my "computer"?). And they will give you (by e-mail!!!) the ability to install DAVID on another comp only if you prove him that previous computer is died. Very dumb and greedy policy.
In the second approach they just give you the big (not notebook sized) USB flash disk from which you may work from any comp and which will stick from your notebook (with risk to break it and notebook USB port), and which may be burned out (I think then you just loose your license)... I even don't talk about speed of work with that flash disk and its reliability...
So, I'm still thinking about the soft... perhaps will write my own little by little...
About laser - no, it is the past already. New technology, more precise, and dramatically faster - is structured light tech. For that you don't need the laser, you need the DLP projector. And if your cam is fast enough you may get scans in about 1 sec. And no more motor is needed.

I looked at that tech while ago - and I do have a DLP projector (and the Quickcam 9000 PRO, and an DSLR) what is the hardware you need?
- now the question how accurate is it, and what about the object parts that are in shadows?
Also you can do some 3d capture with the xbox kinetict - it doesn't have a great resolution, but it works with open source software.. the technology is out there, it just has to go HD and easy to work with
the bottom line, is the quality sufficient to use it?
.. writing your own software would be great, set up a forum and we will give you quality user feedback and ideas (bitching and whining) - you can start with the kinetict and upgrade on that
also there is this free one from autodesk: http://www.123dapp.com/catch take photos and upload to autodesk cloud and it process it back in 3d
and this?

That were the materials that I bought for assembling the calibration panels.
That is what was made.
About projector. I knew that there is no need of color projector. Also I knew that the only big drawback of DLP projectors is a "rainbow" at the enges of stripes. That rainbow is prodused by the detail that gives to projector its color: the colorwheel. That is mechanical wheel that spins very quickly inside projector. So, I just thought to buy the projector, dissect it, and amputate the colorwheel. Moreover, removing this extra colorglass from the light canal, increases so needed projector brightness.
But! First I called some people who sell his projectors. And imagine: I call the man about his Acer PD723P (1024x768), and he says "lamp is almost new, but it does not work well, its colorwheel is broken (one segment is broken), and it vibrates a lot and projects almost black-white image". I said that it is very bad, I don't like to watch the black-white movies, and the vibrating device is suitable only for parts, but I will buy it if he want for 100$.
He even brought it to my work office!
I disassembled it, cleaned the optics, repaired the image flicker that appeared after 5 minutes of using (it was just dirty colorwheel motor speed sensor that I just cleaned), cleaned it outside with monitor cleaner, and got almost new projector with cool features and even laserpointer in the remote for my cat.)) Without the rest of colorglass pieces on the motor it already does not vibrate. And it is black-white, without rainbow-effect, that is ideally for 3D-scanning. A little help from family members. Colorwheel without colorglass, just motor (it will NOT work without spinning motor, as the firmware watches its speed by sensor!). More scans will post some later, I'm just overloaded with other work these days... And I'm already trying to play with writing some own code for that scanning... perhaps just plugin for some 3D software, or standalone, I don't know... perhaps I will just have no time for it, my main work loads me full days...
