I'm currently in active phase of experiments with cheap 3D scanning. Firstly I used Kinect, and now switched to photogrammetry technique. Kinect makes more acurate scan with everything in place, but kind of not enough detailed. For Kinect I'm using ReconstructMe - it's most adequate sollution in the market, and can be used for free. Also "ScanBoth" automation scripts makes life much easier (http://jherrman.com/2012/10/introducing-scanbooth/).
Here is attached image of scan of my brother.
Also I tried glasses mod (http://reconstructme.net/2012/03/26/reconstructme-with-glasses/) for myself. It gives way more detailed result, but adds some kind of distortion and very hard to make 360 degree scan. I think it's maximum which can be achieved using Kinect sensor.
Have big hopes that ReconstructMe team will find a way to implement scanning with Leap Motion (https://www.leapmotion.com/) coz it have 10 micron resolution! 0_o wow. Already orderd two pcs
They said it should be possible and they have been chosen for Leap Developer program.
For now (until my pre-ordered Leap will be mailed in mid-May) I switched to photogrammetry. Here is first results made with Nikon D40 (6 Mpix) camera. Here is "Statue" of three ordinary clothes pins and there is plenty of room to be improved.
Photos can be uploaded to these free services:
But only Autodesk's 123D worked well and in timely manner (few hours). "my3dscanner.com" also worked good, but it is way more demanding on quality of photos and took 24-48 hours to process them.
Arc3d results was complete mess, but it made it in hour
Cubify is still in beta and very glitchy - from 10 attempts to upload photos only one was successfull. PHOV service never bothered to process any of my uploaded photos.
Hope this will help somebody.
