3d scanner recommendations. As far as scan time, most of ringzero's comments are way off the mark. 30 scans to cover a typical object is ridiculous.
For many applications a complete model isn't a requirement. 1 - 3 scans can create very usable results (The face scan in my gallery is just 2 scans). If you want to capture the entire surface of an object the number of scans depends on the complexity of the object's shape. Michael Ang » 3D Printing from Processing. Build a 3D Scanner From A $25 Laser Level - Systm. 3-D Laser Scanner. Create your own super hi-tech 3-D laser scanner.
Using just a laser pointer, wine glass, rotating platform, and a digital video camera, you can make accurate 3-D models of an object or person. Now on Know How!

How to Make a 3D Laser Scanner. #7 week / 3D scanning and printing. 3D scanner using standard webcam @Makezine.com blog. With so much cool stuff popping up these days you notice when something truly draws awe.
Qi Pan, a PhD candidate at the Engineering Department of Cambridge University, has developed a novel approach to capturing 3D objects with a standard webcam. Called ProFORMA, Pan’s software digitizes and image maps an object in 3D as the user rotates it in front of the camera in realtime. Additionally, the physical object can be used as a marker to overlay the virtual object in realtime for potential Augmented Reality applications. [via Core77] As the user rotates the object in front of a stationary camera, a partial model is reconstructed and displayed to the user to assist view planning. Adam Flaherty I make cool stuff and write about other people making cool stuff on makezine.com.

It uses 3 high resolution cameras in conjunction with a self-positioning target system alleviating any need for external tracking devices during scanning. And on top of all that it looks like special issue starfleet equipment. (and most likely costs about as much.) Online : LEGO NXT 3D scanner. LEGO hacker Philo Hurbain needed a way to model some of the more complex LEGO parts for use in the LDraw LEGO CAD program.
Most LEGO parts are easy to model, but something like the tiny LEGO frog, shown above, is a little more tricky. Philo’s solution: a 3D scanner made entirely of LEGO, save for a needle that’s used as the probe. I am a LDraw parts author, and as such I am always interested to find new ways to model LEGO parts. Many parts have a clear geometric structure and are relatively easy to create, but parts like the frog pictured above have no defined geometric shape and are very difficult to model. I toyed for a while with the idea of a 3D scanner… The solution came with 2008 LEGO Technic sets that include a new part, the linear actuator.
If you’re interested in making one of these, Philo has posted the MLCad files for the device, the pbLua source that operates the NXT brain, and instructions for turning the scan coordinate log into a usable mesh.

Hubert’s Laser Page has lots of cool laser projects documented.
One section that caught my eye was one where he covers many ways of making an inexpensive XY laser scanner. Go and have a look at his article for details on using a CD player actuator, Piezo buzzer, Hard disk head actuator and Loudspeaker to get the task done. Unlike my hard drive oscilloscope, Hubert uses a computer to control the laser. “Hard disk head actuators : Hard disk are very well made components very easy to get free.

User_manual:getting_started [DAVID-Wiki] (click here for DAVID 3.x manual) Welcome to DAVID If you don't like reading manuals...
Sorry, our software cannot automatically adapt to your environment; it needs your help. That's why you should read the manual or at least the following 5 hints: The background structure “Calibration Corner” must have an exact 90° angle. (Left: New “V3” calibration pattern. During scanning, the image (i.e. the exposure and aperture settings and the ambient light) must be very dark. The Scan Quality Feedback in the Scan Result window will help you optimize your scan conditions. You must hold the laser rather “high”, i.e. the distance between the laser light plane and the camera must not be too small. Those were most critical reasons why our “impatient” beta testers were not immediately successful. Introduction. Free DAVID 3D scanner. How to build a DIY 3D Laser Scanner.
