Abstract

The invention provides a method of converting monocular video into stereoscopic video, the method is based on an image color characteristic and comprises the following steps of providing a monocular video sequence and obtaining an initial depth image of each frame of flat image in the monocular video sequence; converting each frame of flat image in the monocular video sequence into a grey level space; carrying out depth filling on cavity pixel points of the initial depth images according to converted gray level images; carrying out combined bilateral filter processing on the initial depth images which are subjected to filling according to the chromatic aberration of RGB (Red, Green and Blue) three channels of each frame of flat image to obtain a smooth depth image; and converting the monocular video sequence into a stereoscopic image sequence according to the smooth depth image of each frame of flat image in the monocular video sequence. According to the embodiment of the invention, no manual participation is needed, the all-automatic conversion of the monocular video into the stereoscopic video can be realized; the processing is simple and rapid; and the whole stereoscopic display effect is excellent. The invention also provides a system of converting monocular video into stereoscopic video, based on the image color characteristic.

Description

technical field [0001] The invention relates to the technical field of computer multimedia, in particular to a method and system for converting flat video into stereoscopic video based on image features. Background technique [0002] Stereoscopic video is the main development direction of the film and television industry in the future. The display effect of stereoscopic video is clear in layers, bright in color, has a strong visual impact, and leaves a deep impression on the audience. However, a key problem hindering the promotion of stereoscopic industry is the lack of stereoscopic video. Existing various video media generally exist in the form of a plane, and these video media have lost the depth information of the specific scene while acquiring it. However, using the stereoscopic technology of flat video, the production cost of directly converting flat video into stereoscopic video is much lower than directly shooting stereoscopic video, and any group of existing flat v...
