Microsoft Kinect Turntable 3D Scanner

A fast scanner prototype I built a few days ago. The software is a slightly modified version of Nicolas Burrus' RGBDemo 0.6.0 SLAM and RANSAC-based Kinect real-time reconstruction code.

It works pretty well considering the $150 total price tag!

Tried the Nyko.

It does what I suspected. Makes the field of view wider. So even if I mice the Kinect 40% closer, it sees the same as if I had no lens.

Boo.

Ball pivoting. Yes. :)

Could you increase the resolution by using the 'nyko zoom' attachment to the kinect?

[ajeromin]

@Metapharsical , that was my thought when i saw it. I've yet to try it, but I'm not entirely sure what will happen. The Nyko lens is actually widening the field of view (in order to see more in smaller spaces), so I'd have to move the scanner closer to the object to fill the same amount of screen space (sensor space) as I had without the lens right?

I'm thinking that retro-fitting the Kinect with a zoom lens set over the cam and IR projector would achieve more of what we're after.

Thoughts?

[ajeromin]

Thank you. I've done both.

This video shows me rotating manually.

I now have a 1 rpm motorized lazy Susan I made from a surplus motorized window curtain motor.

Good luck! Thank Nicolas for his software when you get a chance! :)

The markers are just giving the software something to track visually instead of a plain white box. RGBDemo's reconstruction code works by tracking pixel info from the color camera. I didn't change any code for that. Nicolas' code will work fine as is if you build this.

correction, sorry u use the rgb!!!

The image is IR so what's the led lighting for exactly?

@ajeromin I wonder if you were to combine the slam with photogrammetry solutions like pmvs2, the point cloud could be converted to a dense point cloud. I am working on my own solutions for better results

Why the board need to be posted with tapes?

@ajeromin Nice work! have you tried the Nyko lens or any other one ? It would be very interesting to know how it worked.

By "rolling ball" did you mean "Ball pivoting" surface reconstruction in meshlab?

[Metapharsical]

@ajeromin yes, I was mistaken. it's a laser point distribution, widening would lower your dpi. It would only be useful in this arrangement when the object had such large concave surfaces that they would be occluded by the current angle of view. That said, it would be rare, and would only happen on the vertical axis because you're rotating the rest. You're right, I dunno, take the nyko and flip the lenses 180° ?? Do you need specific IR filtering lenses or is that redundant?
