Detection method and device of three-dimensional film source reverse view

Abstract

The invention provides a detection method and device of three-dimensional film source reverse view, and relates to the multimedia field. The problem in the prior art that the picture playing effect is seriously influenced since the reverse view phenomenon is not solved is solved. The method comprises the following steps: selecting N frames of first original images in a to-be-detected film source, wherein N is a natural number and is not smallerthan 1; acquiring a detection region in the first original image, wherein the detection region is located in the upper left part or the upper right part of the first original image; acquiring a matching region in the first original image, wherein the pixel difference of the matching region and the detection region is smaller than a first preset value; determining whether reverse view the first original image occurs according to the position information of the matching region, the position information of the detection region and the filmsource format of the to-be-detected film source; and determining whether the reverse view of the to-be-detected film source occurs according to the reverse view determination result of the N frames of first original images. The scheme provided by the invention can accurately judge whether reverse view the to-be-detected film source occurs, so that the reverse view phenomenon can be solved, and the picture playing effect is guaranteed.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a method and device for detecting the reverse view of a three-dimensional film source. Background technique [0002] At present, stereoscopic film sources are composed of two or more (eg, 8) images. For a three-dimensional film source composed of two images, the two images can be merged left and right, or up and down. For a three-dimensional film source composed of multiple images, there are more image storage formats. Therefore, when the three-dimensional film source is played, the anti-view phenomenon caused by the wrong arrangement order of the images often occurs. If the anti-view phenomenon cannot be solved, the picture playback effect will be seriously affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and device for detecting the reverse view of a three-dimensional film source, so as to solve the reve...
