Embodiment Construction

[0034] The embodiments of the present application provide a method and device for generating a virtual view to solve the technical problem of holes in the virtual view existing in the prior art and improve the quality of the virtual view.

[0035] The technical solution in the embodiment of the present application is to solve the above-mentioned problem of voids in the existing virtual view, and the general idea is as follows:

[0036]After obtaining the original image and the original depth map of the original image, firstly, based on the adaptive filtering algorithm, the original depth map is preprocessed to obtain the processed depth map, and the vertical edge with a large depth change is smoothed and the level is preserved as much as possible. edge, thereby effectively reducing the number of holes in the subsequent generation of the basic view and the distortion of the image. Then, based on the original image and the processed depth map, the basic virtual view is generated....

Abstract

The invention provides a method and device for generating a virtual view, which are used to solve the technical problem of holes in the virtual view in the prior art and improve the quality of the virtual view. The method includes: obtaining an original image and an original depth map of the original image; preprocessing the original depth map based on an adaptive filtering algorithm to obtain a processed depth map; based on the original image and the processed The depth map is used to generate a basic virtual view; layered hole filling based on a deconvolution algorithm is performed on the basic virtual view to generate a virtual view.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for generating a virtual view. Background technique [0002] With the development of electronic technology and the wide application of 3D display technology, the traditional human-interactive manual 2D-3D conversion is far from meeting the needs of the market. Therefore, the automatic 2D to 3D conversion technology has great potential value. [0003] In the existing technology, the automatic conversion technology includes two core steps: (1) generation of depth map; (2) generation of left and right virtual views. The task of step 1 is to find the depth information of the third dimension of the 2D image space from the 2D image and save the depth information in the form of a depth map; step 2 uses the 2D image and the depth map obtained in step 1 to generate the left and right views necessary for 3D image display . But because some pixels in the new view cannot...
