Embodiment Construction

[0029] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.

[0030] figure 1 is the schematic for generating the target image through a parallel camera setup.

[0031] Such as figure 1 As shown, I l is the reference image, its width is W i (pixels), I r for the reference image I l The target image with the same image size. Pixel u l is the reference image I l Points on , whose normalized homogeneous coordinates in the image pixel coordinate system are [u l , v l ,1] T , the scene point U is the pixel point u l For a point projected into a three-dimensional space, its normalized homogeneous coordinates in the world coordin...

Abstract

The invention discloses a method for regulating audience perception depth of a three-dimensional image. A parallel camera is used for setting in a three-dimensional television system to generate a target image, and then, a reference image and the target image are horizontally moved simultaneously towards a center point of a connecting line of the reference image and the target image to obtain a horizontal sensing parallax error of a camera space; according to the geometrical principle of display of the three-dimensional television system, a method for expressing the audience perception depth by using the horizontal sensing parallax error is determined; and finally, according to the relationship between the horizontal sensing parallax error and the horizontal screen parallax error, the audience perception depth is converted into parameters of the camera space, therefore, audiences can regulate horizontal displacement, base line distance and focus parameters to regenerate a target imageso as to regulate the audience perception depth. Through experiments, different perception depths of three-dimensional images required by the audiences can be generated according to the method disclosed by the invention.

Description

technical field [0001] The invention belongs to the technical field of depth image rendering, and more specifically, relates to a depth-image-based rendering (abbreviated as DIBR) method for adjusting the perceived depth of stereoscopic image viewers. Background technique [0002] Depth-image-based rendering (DIBR for short) technology is based on a reference image (reference image) and its corresponding depth image (depth image) to generate a new virtual viewpoint image, that is, the destination image (destination image). ). Compared with the traditional 3D video format that uses two channels of plane video to synthesize 3D images, after adopting DIBR technology, only one channel of video and its depth image sequence are needed to synthesize 3D images, and the switching between 2D and 3D can be realized conveniently. , while avoiding the computational complexity of 3D space transformation brought by traditional view generation methods. Because of this, DIBR technology has...
