Abstract

The invention provides a three-dimensional video rendering method and a device. The method comprises the following steps of: inputting a depth map and a video synchronous signal, acquiring a depth value of each pixel in the depth map, and gradually calculating reverse co-ordinates of the pixels according to the depth map; and sampling and dereferencing the video synchronous signal to obtain a three-dimensional video rendering result, and outputting the three-dimensional video rendering result. According to the method in the embodiment of the invention, a cavity is formed after releasing render, the cavity detection and filling steps are omitted, the calculated amount is relative small, the rendering treatment rate is improved, and meanwhile, the requirements on hardware resource is reduced; and the method has no strict requirements on the smoothness of the depth map, can receive the depth map after filtering, can receive the depth map the edge of which has larger saltation, and has wider application area.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a stereoscopic video rendering method and device. Background technique [0002] Depth maps play an extremely important role in stereoscopic video capture, post-production, and video conversion from 2D to 3D. At the current level of technology, people already have a variety of channels to obtain the depth map corresponding to the 2D video, but when the 3D video is finally presented to the audience, it still needs to have high-quality images from different perspectives, and the use of The process of generating images with different viewing angles from the depth map is generally called stereoscopic video rendering based on the depth map. [0003] Traditional depth-based stereoscopic video rendering generally includes the following steps: 1. Calculate the disparity value based on the depth value 2. Calculate the forward coordinates of the image based on the disparit...
