Embodiment Construction

[0056] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0057] The embodiment of the present invention implements the method and device for converting a two-dimensional image to a three-dimensional image. Aiming at the problem that the existing method of generating a depth map based on motion and image classification is too complicated to meet real-time requirements, the original two-dimensional image is used to The depth map is generated in the area, and the target image is generated by using the depth map. Finally, the original image and the target image are fused to generate a binocular stereo image to realize the conversion from 2D to 3D.

[0058] Such as figure 1 Shown is a flowchart of a method for converting a two-dimensional image to a three-dimensional image...

Abstract

The invention relates to the technical field of image processing and discloses a method and a device for realizing conversion from a two-dimensional image to a three-dimensional image. The method comprises the following steps of: inputting the original two-dimensional image; determining interesting areas in the original two-dimensional image for a user; respectively using the interesting areas inthe original two-dimensional image for the user as prospect areas, using non-interesting areas as background areas and generating a prospect histogram and a background histogram; calculating color difference distribution of the prospect histogram and the background histogram; generating a depth map according to the color difference distribution; generating a target two-dimensional image accordingto the depth map; and generating a binocular three-dimensional image by fusion of the original two-dimensional image and the target two-dimensional image. According to the embodiment of the invention, the scheme implementation is simple, and the real-time requirement can be met.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for realizing conversion from a two-dimensional image to a three-dimensional image. Background technique [0002] At present, the creation, production and transmission of 3D images have become a popular technology today, but the 3D camera used when shooting 3D images has two cameras, which is much heavier than ordinary cameras, and requires photography technology, as well as when adjusting the optical axis. special experience. For this reason, 2D-3D conversion technology has emerged, that is, to make three-dimensional images on the basis of two-dimensional images. The 2D / 3D conversion can not only be applied to games to provide users with a more realistic visual experience, but also can be applied to online video to truly bring 3D effects to users. [0003] There are four main types of existing 2D-3D conversion technologies: light-splitting,...
