High-speed transition patterns for video projection, 3D reconstruction, and copyright protection

作者：

Highlights：

• We present a camera projector system that allows for 3D reconstruction and copyright protection at the same time.

• Our system retrieves dense 3D maps at a rate of 11.25 fps.

• Our 3D maps have an accuracy of +/− 56 microns.

• A FPGA implementation of our dithering algorithm can be connected to most DMD controllers.
