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 present invention relates to the technical field of computer vision, in particular to a method and device for stereo conversion of planar images. Background technique [0002] Flat-to-three-dimensional technology, also known as 2D to 3D technology. Flat-to-stereo technology refers to the use of existing flat videos to extract the depth information in the corresponding scene of the video through necessary technical means, and then simulate the virtual scene observed by the left and right eyes to achieve the effect of stereo perception. [0003] In stereo video technology, stereo perception effects are realized through binocular stereo vision. Specifically, binocular stereo vision uses the principle of binocular imaging to simulate binocular perception imaging, using the left and right images or videos as the input for the left and right eyes, and then reconstruct the input two images and videos through the fusion of the brain The three-dimensional scene,...

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
