Problems solved by technology

[0003] However, the existing 3D conversion algorithm has the following defects: due to the use of the translation algorithm, the overall image will be translated, resulting in the overall movement of the picture, there is no distant and near view, so there is no real 3D deformation process, and the overall movement results in the loss of some content
In addition, although the time axis algorithm can satisfy the requirement of keeping the background unchanged, the use of object displacement to create a 3D effect is likely to cause a series of problems such as visual confusion, unclear motion, and jitter, and the user experience is not good.

Abstract

The invention relates to a three-dimensional image conversion method and device. The three-dimensional image conversion method comprises the following steps: carrying out boundary identification on an input image to be processed to obtain object image blocks of the image to be processed; carrying out de-noising processing on the object image blocks to obtain image blocks to be converted; and determining deformation and displacement of each image block to be converted obtained after de-noising processing by adopting a spindle body model to simulate a three-dimensional visual effect of each image block to be converted in the image to be processed. The three-dimensional image conversion method and device are on the basis of object deformation and visual effect; only objects in the image need to be identified and the objects are divided; and then, with the spindle body model being as a reference system, deformation and displacement and the like can be carried out on the objects in the image according to the spindle body visual effect, thereby improving three-dimensional experience of a user.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a three-dimensional (3Dimensions, 3D) image conversion method and device. Background technique [0002] At present, more and more videos are played using three-dimensional playback to display more realistic visual effects. Since the computer screen is flat and two-dimensional, to display a real three-dimensional image in the computer, the video and / image can be converted from two-dimensional to three-dimensional. Traditionally, non-3D movies (such as 2D movies) are converted into 3D movies, and the technologies adopted are: shifting the screen to obtain an algorithm with displacement difference; or adopting the time axis concept and using time difference images to perform 3D reset. [0003] However, the existing 3D conversion algorithm has the following defects: due to the use of the translation algorithm, the overall image will be translated, resulting in the overall mov...
