Good camera for 3d scanning

[jeffrey001]

Hi, would like to build a 3d scanner and would like to buy a good camera.

What would be a good choice.

Maybe in the $50.00 to $100.00 range

Thanks for your help.

I think Logitech 9000 Pro, is a good choice.. I am using it with superb results..

I used the Logitech 9000 on my David-Scanner setup and was able to make decent 3D scans. I don't use it anymore if anyone wants to buy it; I built a housing to replace the cheesy plastic stand so I could mount it securely on 80/20 extruded aluminum for 3D scanning.

If you can find a 1.3-2mp CCD machine vision camera (sometimes they can come up cheap on ebay) it makes a huge difference in the ease and quality of capture. I found the webcams introduced a bit more noise in the scan, and required a lot of adjustment to get good results. Pay attention to the frame rate too; 5 frames per second is painfully slow with a laser; you really want 15+ frames per second to keep from going insane during scans; especially if you are moving the laser by hand.

Hello Dan again,

please take a look at C910 webcam from Logitech. It beats the 9000 model (I own them): much more resolution and more fps. If possible use some cnc to move the laser, you will laugh with your last hand-made movement.

I posted also today this: please look the kinect cam that Xbox360 is going to launch right now. 145$, t-o-f cam, with pc drivers next 2011. Imagine it working with pairs...

Hello Dan,

just looked your site, you know what you're talking about! be lucky on your adventure!

Just one "simply" question: do you manage with billateral scanned objects? Do you try to extract bilateral planes? Do you know what I mean? I my work is essential to extract this information as accurate as possible, and I spend lot of time on this. Till now no real good method in my way...

Thank you and regards,

Toni

it's a lot to do with the lens your using, I tried flexscan with a canon eos 400d (dslr) and a prime 50mm lens (f stop about 22 in bright light) and a 70-200mm, in at 200 fstop 16. got some good results. both lenses exhibit low curvature at the peripheries.
