Low cost 3D scanner

Postby droomurray » Sat Mar 28, 2015 8:50 pm

Guys,

Im thinking of taking this project :- http://www.pi3dscan.com and modifying it to make an arm scanner. The idea being a smallish device you put your arm in and it captures enough photo's to generate a 3D model.

I have worked out that it is possible to change the focal length of the camera's.
To scan skin we would need to project some "noise" to help the software be able to read the pictures to convert them to a 3D Model.
Rather than using a projector or multiple projectors I was thinking at looking something like this - http://3dprint.com/30368/stereographic-lampshade/

I have spoke to the creator of the project above and he has offered to advise / get involved.

So does anyone think it is worth investigating ?

Drew.

I have started sourcing bits for this development, already have 2 donated raspberry Pi's :-)

Will keep posting on progress.

I've been giving this some thought too. What you need is a low cost projector. I think a pattern printed on some clear Printable Acetate Sheets, mounted in a box with a light source, and a low cost fresnel lens on the front to project it. You would take two sets of photos, one with the pattern, one without. you would use the photos without the pattern as your texture (if it's important to collect the texture!)

Drew,
Have you tested the low-tech idea Aaron Brown used of making a photocopy of a hand using a flatbed scanner? Steve Wood tested it for feet when experimenting with his 3D printed Insole project.
