Calibrating mapping with embeded light sensors

I'm sure many here have seen this:

So my question is has anyone tried something like this? This seems WAY faster and easier than using a DSLR. I have several polygons I want to have mapped and perspective warped, and this looks like it would be amazing to do that in a matter of seconds. Anyone know where I can learn more about how to actually do this (yes I have read over his thesis-he doesn't actually talk about the mechanics of building the sensors or the software used to read the data, etc).
THanks!

Microvision has a mobile laser projector and an API that could do that with small stick on retroreflectors you could put at the corners of your polygons. The Macrovision app is waving your hands around with retroreflector gloves as a multitouch interface in front of a projected image.

Well I definitely want to use my own projector....

Warping is the easy part, really. It's not rocket science to move points around with your mouse. The secret to great mapping is great content.

I agree of course content is important. However, This will be an incredible time saver in my situation with multiple polygons on a stage where night to night the shapes will be slightly different distances from each other. With this system, the whole process would be completely automated.

there are a lot of cables and fragile optical fibres in that system.

setting it all up on stage will take longer than tweaking a preprepared composition using the traditional techniques of projection mapping.

a DSLR is not part of this process. you simply use your eyes, a computer and a helpful test pattern along with the controls built into the projector.
