In the context of 3D video systems, depth information could be used to render a scene from additional viewpoints. Although there have been many recent advances in this area, including the introduction of the Microsoft Kinect sensor, the robust acquisition of such information continues to be a challenge. This article reviews three depth-sensing approaches for 3DTV. The authors discuss several approaches for acquiring depth information and provides a comparative analysis of their characteristics.
