Method and device for converting planar image into stereoscopic image

Abstract

The invention discloses a method for converting a planar image into a stereoscopic image. The method comprises the following steps of: inputting the planar image and preprocessing the input planar image; calculating the initial depth map of the preprocessed planar image; performing filtering postprocessing on the initial depth map to obtain the depth map of the planar image; and performing pixel shifting on the planar image according to the depth map of the planar image to obtain a virtual view, and synthesizing the planar image and the virtual view in a stereoscopic form so as to generate and output a stereoscopic video. The method for converting the planar image into the stereoscopic image is convenient to use, and has high processing efficiency and a good stereoscopic display effect. The invention also discloses a device for converting a planar image into a stereoscopic image.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and device for stereo conversion of a plane image. Background technique [0002] Plane to stereo technology, also known as 2D to 3D technology. Plane-to-stereo technology refers to the necessary technical means to extract the depth information in the corresponding scene of the video through the existing planar video, and then simulate the virtual scene observed by the left and right eyes, so as to achieve the effect of stereo perception. [0003] In stereoscopic video technology, stereoscopic perception is achieved through binocular stereovision. Specifically, binocular stereo vision uses the principle of binocular imaging, and by simulating binocular perception imaging, the left and right images or videos are used as the input of the left and right eyes, and then through the fusion of the brain, the input two images and videos are reconstructed stereoscopic sc...

Problems solved by technology

The development of 3D technology has a long history. With the development of 3D shooting, 3D production and 3D display technology, 3D has been gradually popularized and entered thousands of households. However, the lack of 3D content has seriously restricted the development of the entire 3D video industry. develop

[0006] However, the development of plane-to-stereo technology is still immature. There are very few 2D-to-3D production software based on image color characteristics for ordinary consumers. At present, there is no complete and practical planar image or video to stereoscopic image or stereoscopic video on the market. s solution
