Problems solved by technology

In the video, objects far away from the viewer often move fast, and objects close to the viewer move slowly. At this time, if the traditional method is used to process it, a wrong disparity map will be obtained.

Embodiment Construction

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0020] In the method for generating a stereoscopic depth map of a planar video provided by an embodiment of the present invention, the planar video is first input, and then the planar video is divided into two branches: the current frame, the current frame and the reference frame, and the static model depth map and the depth map of the current frame image are respectively generated. The depth map of the dynamic model is then deeply fused with the depth map of the static model and the depth map of the dynamic model to obtain the fused dept...

Abstract

The invention discloses a depth map generation method for plane video three-dimensional conversion, comprising the following steps of: segmenting a current frame image based on scene static model distribution to obtain segmented regions, marking pixels and clustering the pixels to different regions to generate a static model depth map of the current frame image; selecting characteristic points ofthe current frame image and a reference frame image, calculating a motion vector of a moving object, and performing motion analysis on the motion vector to obtain motion analysis result of the current frame image and the reference frame image; generating a dynamic model depth map of the current frame image according to the segmented regions of the current frame image and the motion analysis result of the current frame image and the reference frame image; and adaptively fusing the static model depth map and the dynamic model depth map of the current frame image. The invention further disclosesa depth map generation device for plane video three-dimensional conversion. With the method and the device, a static model and a dynamic model of a scene are fused, a stereoscopic video with more vivid effect can be obtained, and better stereoscopic effect can be achieved.

Description

technical field [0001] The invention relates to the field of computer multimedia technology, in particular to a method and device for generating a depth map for stereoscopic plane video. Background technique [0002] Stereoscopic video technology (also called 3D video technology) is the development direction of multimedia technology in the future, and stereoscopic video can provide a new type of video technology with stereoscopic effect. Compared with single-channel video, stereoscopic video generally has two video channels, and the amount of data is much larger than single-channel video. Stereoscopic video can provide a sense of three-dimensionality that human vision can perceive. Nowadays, 3D technology has been widely used in many fields, including communication, broadcasting, medical treatment, education, computer games, animation and so on. In addition, the rapid development of 3D displays enables people to feel a better three-dimensional sense and obtain maximum eye ...
