three-dimensional vision system XBOX Kinect

Sensor Kinect, developed by Microsoft, based on depth sensors of PrimeSense.
IR receiver combined with Kinect infrared emitter and processing algorithms of backlight distortion is actually a three-dimensional scanner based on structured illumination which allows to build a scene depth map as a point cloud, coordinated in height, width and depth in the camera coordinate system.
On the basis of such a depth map is possible to construct three-dimensional model on a robot.
