Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] A kind of stereoscopic image repositioning method that the present invention proposes, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:

[0048] ①The left viewpoint image, right viewpoint image and left disparity image of the stereo image to be processed with width W and height H are correspondingly recorded as {L(x,y)}, {R(x,y)} and {d L (x,y)}; among them, 1≤x≤W, 1≤y≤H, both W and H can be divisible by 8, L(x,y) means that the coordinate position in {L(x,y)} is ( The pixel value of the pixel point of x, y), R(x, y) represents the pixel value of the pixel point whose coordinate position is (x, y) in {R(x, y)}, d L (x,y) means {d L The pixel value of the pixel whose coordinate position is (x, y) in (x, y)}.

[0049] ②Split {L(x,y)} into non-overlapping quadrilateral grids with...

Abstract

The invention discloses a three-dimensional image relocation method. According to the method, the shape protection energy term, the shape consistency energy term, the boundary curvature energy term and the comfort maintaining energy term of a left viewpoint image are extracted. Meanwhile, the total energy of the left viewpoint image is minimized and an optimum similarity transformation matrix is obtained through optimization. In this way, an obtained relocated three-dimensional image can better reserve the important significant semantic information and maintain the visual comfort. The horizontal coordinate position, the vertical coordinate position and the depth value of the three-dimensional space of the three-dimensional image are adjusted at the same time. As a result, the important significant information of the left viewpoint image can be preserved after the relocation process. At the same time, an obtained left viewpoint image and an obtained right viewpoint image after the relocation process are matched with each other. Therefore, the comfort of the three-dimensional image after the relocation process is ensured.

Description

technical field [0001] The invention relates to an image signal processing method, in particular to a stereoscopic image repositioning method. Background technique [0002] With the rapid development of stereoscopic display technology, a variety of terminal devices with different stereoscopic display functions have also appeared widely. However, due to the wide variety of stereoscopic display To display on different stereoscopic display terminals, the image size must be adjusted first to achieve the effect of stereoscopic display. Traditional image scaling methods are by cropping or scaling by a fixed ratio, which may reduce the content of the image or cause significant object deformation. [0003] For stereoscopic images, stretching or shrinking along the horizontal or vertical direction will seriously affect the stereoscopic effect, resulting in changes in binocular parallax, resulting in changes in stereoscopic depth perception, and in severe cases, it will cause visual ...
