Abstract

The invention discloses an imaging method and system of a three-dimensional image. According to the method and the system, two-dimensional images provided by at least three cameras which are located on the same line and have the consistent optical axis direction, and space information of each camera are obtained, wherein the two-dimensional images include common image regions; based on the common image regions of two to-be-paired two-dimensional images, the two-dimensional images are pre-processed based on space reconstruction; based on each pre-processed pair of the two-dimensional images and the space information, space pixel values of a to-be-displayed three-dimensional image are reconstructed; and the reconstructed space pixel values are projected on a preset screen used for displaying the three-dimensional image, and the three-dimensional image is obtained. According to the method and system, the problem of poor stereo perception of the three-dimensional image is effectively solved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular to a three-dimensional image imaging method and system. Background technique [0002] A three-dimensional image is to use two projection devices to project two views with overlapping images on the same screen, and use polarized glasses to present the two views in two eyes, thereby displaying an image with a 3D effect. [0003] In the above presentation mode, people must wear polarized glasses. With the development of three-dimensional image technology, glasses-free 3D technology hopes to present a three-dimensional image to people by changing the grating structure of the display screen. To do this, the existing two views need to be interleaved into one 3D image. [0004] In order to solve the above problems, in the prior art, by estimating the parallax of each point in the overlapping area of ​​the two views, the sub-pixel positions of the RGB values ​​in ...
