Amazing mapping tool in development

[evomedia]

Amazing mapping calibration work going... this guy is developing a 'spatially augmented reality toolkit', using light sensors to calibrate and map the projector

Thats pretty cool, was only a matter of time really til someone combined a mapping routine/images with a camera to do this automatically.

I fail to see the innovation - care to explain what's amazing about it ?

I believe its automatically doing the mapping to the object by comparing test grid projected with what a camera sees when pointed @ the projected lines/grid.

not precisely; there are sensors (photodiodes) embedded in the box (at the corners presumably) which calculate their position in the projector cone from the light/dark pattern sequence illuminating them.

Yep that's how it works, why is that exciting? well essentially you could throw a screen up anywhere and the image could auto align to the screen,

If you had a mapping installation with multiple boxes, rather than having to take a pic and work back, or sit with a computer and set masks for each target, you could simply thrown the shapes up anywhere and the sensors could feed back the data they recieve and auto align the mapping data. You could practically get anyone to stack boxes or shapes anywhere within the projector field of view and the software could work out where each shape sits and warp the map for each object so its correct perspective wise.

All you would have to do is embed the sensors into each objects corners, tell the software how to interpret them and then you could put the objects in any configuration and they would auto map. Its projection mapping meets augmented reality, basically mapping without the hard work.
