There is also an RGB color camera that allows color images also to be extracted. The camera is sensitive to the displacement of the dots from the known location that they would be for planes at infinity when a close object is imaged. In fact the pattern of dots is a known thing to the hardware. This means that the location of the spots changes in the camera image as the object moves further away. The hardware is able to recover the 3D depth because there is a distance between the center of projection of the speckle pattern and the optical center of the camera. The Kinect has a camera that can pick up the IR pattern. The Kinect uses an infra red laser speckle projector to project a dense pattern of dots on the whole scene which are infra red and therefore invisible to the eye. I have worked on the Kinect and its hardware and I have written code for recovering 3D depth using similar techniques. George Herold George Herold $endgroup$ $begingroup$
