The analysis and reconstruction of 3D scenes from video data is an important theme in computer vision. Recently, novel cameras have emerged that allow to capture not only color, but also the depth of the scene in realtime. Such devices, like LIDAR, time-of-flight imaging, or the Kinect game sensor from Microsoft, facilitate 3D scene analysis enormously and allow for a complete range of novel applications. In my presentation I will first explain the technique and ability of such depth cameras, their combination with traditional color cameras, and then discuss some recent application areas, like auto-stereoscopic 3D-Television, capture and tracking of deformable moving objects, or virtual studio 3D graphics applications, all of which rely on the novel depth devices.
