I want this right now - I've spent the last few days building a man's neck in LightWave and manually tracking it for a VFX shot, and something like this would make that kind of additive effect so much easier!

This is very cool. Strata has had something sorta similar for a while now, but it uses a paper reference disk under the object, and multiple still photos.

I saw a very similar demo in 1995, though the resulting model wasn't as perfect, and I don't think the processing was done in real time back then. A lot of the early research in this area was from military reconnaissance, AIUI. Fly some aircraft over an area with movie cameras, postprocess the films on the ground, and you have a detailed topographic map including all structures etc. To be sure, this isn’t a new thing; Qi Pan has made refinements and improvements on a technique that’s been around for a while.

You can tell it's a lab picture, of course: there is no attempt at making this appear better than it currently is. Given that this is a PhD candidate's effort though, given some luck, Qi Pan'll get funding and perfect this technique. Can you imagine how this might improve virtual acting (given enough cameras), for example? No akward styrofoam balls stuck to you, not weird exaggerations required. Colour me impressed.

It is faster and generates a 3D model at 60 Hz however not with color, and perhaps a bit grainier. It does seem to be more correct in the geometry itself. The idea is similar with turning an object around in front of the camera. I'd like to see what he could do with two cameras and a projector. Also what does it do to a human body? One issue is that this seems to require camera to remain stationary. The implementation I just mentioned uses a handheld video camera which you just move around an object you might hold in your hand if you wish. These approaches need to be melded to allow you to zoom in and match different inputs (color cam, laser, structured light) to gain the maximum in high speed acquisition, resolution, and accuracy of geometry and color. I like most how this is not a point cloud (which he starts with to find landmarks I guess) but actually a carving determined by where the landmark probably is, hidden around the corner. It's cool and seems to match a bit what the human brain does perhaps. Drawback is how the geometry can get messed up and stay that way, vis the webbing left between steeple and nave. I'm not up to the latest though, perhaps someone who has studied the area could answer? These video based approaches seem to be fast and partially self-adjusting (as his finger is mostly not captured) What I have seen in the past that matches this in anyway is using structured light and a video camera.

It acquires a 3d model just by turning the object around in front of the camera. How does it fall short of its goal?
