New 3D Modeing Technique is discovered in Mexico
This is actually some pretty exciting news. Researchers in Mexico have published a report outlining a method of 3D modeling that doesn't require a 3D scaner. Instead it uses a camera and 2 light projectors to beam light at the object from two separate angles. A computer is then able to comprehend the way in which the light if reflected/bent in order to construct a 3D model of it.

Nice. Two leds, a cheap digital camera, lazy susan, and some grids in front of the leds. few printed parts and you've got a 3d scanner.
All we need is the software :-)

OK, so the question is really: "Will 3D scanning render 3D scanning obsolete?"
Um... no. It's still really just another 3D scanning technique. I'm not even sure if it's a new one. Kind of a variation or mash-up of existing ones. It looks like a stereo structured light scanner, if I had to identify it.Last edited by JRDM; 09-07-2014 at 04:37 PM.

No, it isn't really new at all. It's actually almost exactly like how the Xbox Kinect has worked for years. Multiple lines projected in IR and it measures the variation in the lines to see the 3D picture of the persons gestures. This just takes it up a notch by using 2 projectors instead of just one.

As long as it doesn't cost me the $1800 they want for a makerbot scanner, I'm in!

Hi Eddie,
I though I'd pop in let you know I will cover this item tomorrow on '3D in Review.' As you know I also develop scanning software and lens systems (along with VR stuff now) and I have to agree, I don't see this being much different than a number of other projected/structured light techniques like the Faro and Artec scanners. In fact a number of laser scanning devices use multiple laser paths for triangulation and the current Intel Realsense and the just announced 'Core' from Occipital also uses parallax based dual camera system to improving scanning quality and capture integrity. However, there maybe more too this, so I dig in a little deeper before tomorrow.
As always, another interesting find by your team.
Mike

Yep, as I thought the research paper (PDF) explains it in more detail. What makes this unique if co-phased lighting system that uses the fringes derived form the complementary phases canceling each other out allowing an outline in 3D space to accumulated to create a point cloud. Actually it is unique and if the light sources are generic, all you would need is a couple of polarized filters on each light source. I could see this being even more interesting if the light source was a diffused laser source.
