The 3D scanning effect that brought us radiohead’s “House of Cards” video is now within the realm of us mere mortals thanks to the work of Kyle McDonald. In a new project on Instructables, he shows how to connect a projector and 3 cameras together to great a great low-cost 3D scanner.
You’ll need a camera, a projector, and some open source software to process the image data. Using these simple tools, [Kyle] turned out much better video than before. Take a look after the break to see his results from scanning at 60 fps using a PS3 Eye. The trick to this setup is getting the correct synchronization between the projector and the camera, something that could be improved with a bit of extra hacking.
The trick is that the projector casts a cosine pattern onto the field which can then more easily be picked up by the 3 cameras and triangulated to create geometry. It requires a very detailed synchronization between the projector and the cameras & software, but the results are impressive.
See some demonstration results after the break.
