The Kinect sensor consists of an in

The Kinect sensor consists of an infrared laser emitter, an infrared camera and an RGB camera. The inventors describe the measurement of depth as a triangulation process [27]. The laser source emits a
single beam which is split into multiple beams by a diffraction grating to create a constant pattern of speckles projected onto the scene. This pattern is captured by the infrared camera and is correlated against a reference pattern. The reference pattern is obtained by capturing a plane at a known distance from the sensor, and is stored in the memory of the sensor. When a speckle is projected on an object whose distance to the sensor is smaller or larger than that of the reference plane the position of the speckle in the infrared image will be shifted in the direction of the baseline between the laser projector and the perspective center of the infrared camera. These shifts are measured for all speckles by a
simple image correlation procedure, which yields a disparity image. For each pixel the distance to the sensor can then be retrieved from the corresponding disparity, as described in the next section.
Figure 1 illustrates the depth measurement from the speckle pattern.
