Depth Sensing for 3DTV: A Survey

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.This work has been supportedby grant 2009/0264 of the KK Foundation, Sweden; grant 00156702 of the EU European Regional Development Fund,Mellersta Norrland, Sweden; and grant 00155148 ofLänsstyrelsenVästernorrland, Sweden.Realistic3
