Problems solved by technology
[0004] The problem with existing methods for converting flat video into stereoscopic video display is that in the process of generating virtual views for the left and right eyes, hole filling and error checking are required, and the video rendering speed is relatively slow. Video cannot achieve real-time rendering and playback. In addition, the existing stereoscopic rendering method cannot support video signals in multiple color formats at the same time, and the compatibility is not enough.

The invention provides a three-dimensional rendering method of a plane video, comprising the following steps: receiving the plane video, the depth map corresponding to the plane video and the rendering parameter input by the user; judging the color format of the plane video; rendering the plane video so as to obtain the first virtual view and the second virtual view according to the color format of the plane video, the rendering parameter and the depth map; and combining the first virtual view and the second virtual view as one three-dimensional map and outputting. In the invention, the three-dimensional video is rendered by combining the depth map of the plane video, the pixel value can be calculated in the process of calculating the virtual view of the left and right eyes without filling the cavity and testing the error repeatedly, and the rendering speed of the video is increased, thereby being capable of satisfying the demand of real-time playback. Besides, the three-dimensional rendering method of a plane video can process the video of all color formats with strong compatibility.
Description
technical field [0001] The invention relates to the technical field of computer vision, in particular to a three-dimensional rendering method of a plane video. Background technique [0002] With the continuous development of 3D stereoscopic technology and the popularization of products such as stereoscopic TVs and stereoscopic movies, the public has more and more needs for stereoscopic videos. However, limited by existing technical conditions, it is not realistic to produce a large amount of high-quality stereoscopic videos in a short period of time. Therefore, a method is needed to convert the existing 2D plane video into 3D stereoscopic video. [0003] Currently, users usually watch stereoscopic videos by wearing special glasses, such as time-division glasses, complementary color glasses, polarized glasses, and the like. When viewing in this way, the original video needs to be rendered into a virtual view of the left and right eyes first, and then synthesized before it c...
