Abstract

The invention discloses a method and a device for converting a planar video into a stereoscopic video. The method comprises the following steps executed on each frame image of the planar frame: S1, acquiring a depth map D of a current frame image: acquiring a first depth map D1 through motion estimation based on block matching; constructing a second depth map D2 based on a geometric perspective relation through an edge detection algorithm and a Hough transform algorithm; estimating a third depth map D3 through a method based on color information; and executing deep integration on D1, D2 and D3 to obtain the depth map D; S2, generating a multi-viewpoint stereoscopic view through a reference map and the depth map D based on a DIBR (Depth Image Based Rendering) algorithm; and S3, selecting at least a part of left-eye and right-eye views from the multi-viewpoint stereoscopic view according to the stereoscopic video format requirement of a user for executing stereoscopic rendering to generate a color stereoscopic video of a corresponding format. The stereoscopic video generated through the method has a good stereoscopic effect, and stereoscopic videos of different formats can be generated according to user demands.

Description

technical field [0001] The invention relates to a method and a device for converting a plane video to a stereo video. Background technique [0002] Planar video to stereoscopic video technology, also known as 2D to 3D technology, refers to the use of existing planar video with necessary technical means to fully mine the depth information in the planar video, and simulate the virtual scene observed from multiple viewpoints according to the depth information, so as to achieve The effect of stereo perception. In stereoscopic video technology, stereoscopic perception is achieved through binocular stereovision. Binocular stereo vision uses the principle of binocular imaging, and by simulating binocular perception imaging, the left and right images or videos are respectively projected into the left and right eyes of the person using special means, and the human brain will reconstruct the stereoscopic image or video. scene to achieve a three-dimensional perception effect.
