Problems solved by technology

[0005] In the process of converting flat video to stereoscopic video in the prior art, manual participation is required for each step, the degree of manual participation is high, the workload is heavy, and the efficiency of converting flat video to stereoscopic video is low; moreover, the intermediate results of each step need to be saved in the In the hard disk, the video and image files in uncompressed format are very large, so it will take up a lot of storage space on the hard disk

Description

technical field [0001] The invention relates to computer multimedia technology, in particular to a method and device for converting flat video to stereoscopic video. Background technique [0002] With the development of computer multimedia technology, stereoscopic video has been more and more popularized and favored. The so-called stereoscopic video is a binocular or multi-channel video sequence, which includes more than two video sequences, and each video sequence corresponds to the interval between frames. With parallax, it can provide viewers with a left-view sequence and a right-view sequence with parallax information, which is also the reason why stereoscopic video can produce an immersive stereoscopic feeling; however, it is difficult to directly obtain stereoscopic video , equipment cost is relatively high, and the quantity of existing planar video content is huge, so the technology of converting planar video to stereoscopic video has obtained more and more attention....
