Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0059] figure 1 Shows existing 2D / 3D video conversion methods based on depth map rendering, such as figure 1 As shown, for the input 2D video, firstly, the video frame is decomposed from the video stream of the 2D video by decoding; then, the effective depth information is extracted from the 2D video by using various depth cues, and generated by calculation and processing. A depth map corresponding to the video frame; then, the depth map and the video frame are subjected to DIBR rendering processing to obtain and output a 3D video.
[0060] Among them, DIBR rendering processing is an important step in the 2D / 3D conversion method. It describes an accurate point-to-point mapping relationship, and can use the depth information to render a virtual stereoscopic video, thereby finally completing the "2D to 3D" qualitative transformation. ". Although this t...
