Embodiment Construction

[0026] The method for adjusting the depth of 3D image display proposed by the present invention is described in detail in conjunction with the accompanying drawings and embodiments as follows:

[0027] The core of the method of the present invention lies in "adjusting the display depth by changing the parallax", so firstly analyze the sign and quantity relationship between the parallax and the display depth.

[0028] The sign relationship between disparity and display depth is as figure 1 and figure 2 shown. figure 1 Among them, 11 represents the plane where the screen of the stereoscopic display is located, 12, 13, and 14 respectively represent the shooting objects positioned behind, above and in front of 11 in the stereoscopic image during display, 15 represents the eyes of people and the dotted line represents the line of sight of human eyes; The previous definition is the positive direction of the display depth, then the positive and negative display depths of 12, 13, a...

Abstract

The invention relates to three-dimensional image display depth adjusting method, which belongs to the field of three-dimensional image processing technology. The method includes: when synthesizing a three-dimensional image by employing a one-path plane video and corresponding depth video, firstly determining depth value corresponding to the screen plane and conversion ratio of parallax to depth, thereby finding parallax sizes corresponding to different depth areas and shifting each area according to the value to obtain left-right view results; moreover, when synthesizing a three-dimensional image by employing left-right two-path videos, firstly determining parallax size corresponding to the imaging object, and further shifting the imaging object in the left-right two-path videos to obtainleft-right view results. Then, fusion hole-mending treatment is performed to the obtained view results, and a three-dimensional image is synthesized according to the treated left-right views. The invention can amplify depth-motion of the imaging object or push the imaging object to front of the screen, which greatly reinforce stereo perception and visual impaction of the three-dimensional image. The invention is suitable for all the three-dimensional images synthesized based on the left-right parallax principle.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional image processing, and in particular relates to a method for adjusting display depth of three-dimensional images. Background technique [0002] With the development of three-dimensional image and video technology, the display of three-dimensional images has become increasingly mature: ordinary liquid crystal displays can be used to display three-dimensional images as long as they are treated with surface grating film. Although the specific details of the display technology of different sizes of monitors may be different, the basic principle of display is to include the left and right view information in the 3D image. , The right eye only sees the right view, thus creating a three-dimensional effect. [0003] There are two ways to synthesize 3D images: 1. Synthesize 3D images by using one plane video and its corresponding depth video; 2. Synthesize 3D images by using left and right plane ...
