Embodiment Construction

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0055] A kind of three-dimensional video image repositioning method proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:

[0056] ① The left-viewpoint color image, right-viewpoint color image, left-viewpoint depth image and right-viewpoint depth image of the three-dimensional video image to be processed are correspondingly recorded as {I L (x,y)}, {I R (x,y)}, {D L (x,y)} and {D R (x, y)}, where (x, y) represents the coordinate position of the pixel in the three-dimensional video image to be processed, 1≤x≤W, 1≤y≤H, and W represents the coordinate position of the three-dimensional video image to be processed Width, H represents the height of the 3D video image to be processed, I L (x,y) means {I L The pixel value of the pixel whose coordinate position i...

Abstract

The invention discloses a three-dimensional video image repositioning method. Through extracting a shape protecting energy item, a boundary curvature energy item and a comfort degree keeping energy item of a left viewpoint color image, and optimizing an acquired optimal similar transformation matrix, important significant meaning information and visual comfort degree of an obtained repositioned three-dimensional video image can be kept in a relatively good manner. A horizontal coordinate position, a vertical coordinate position and a depth coordinate position of the three-dimensional image in a three-dimensional display space are simultaneously adjusted. Therefore matching between the depth value of the depth image after repositioning and the coordinate position of the pixel after repositioning can be ensured, thereby ensuring high comfort of the three-dimensional video image after repositioning.

Description

technical field [0001] The invention relates to an image signal processing method, in particular to a three-dimensional video image repositioning method. Background technique [0002] With the rapid development of stereoscopic display technology, a variety of stereoscopic display terminals with different stereoscopic display functions have also appeared widely. However, due to the wide variety of stereoscopic display If the image is displayed on different stereoscopic display terminals, the size of the image must be adjusted first to achieve the effect of stereoscopic display. The traditional image scaling method is by cropping or scaling by a fixed ratio, however, this may reduce the content of the image or cause significant object deformation. [0003] For 3D video images, if the scaling relationship of the color image is directly applied to the depth image, the geometry of the camera scene has changed severely after relocation, and if the depth value remains unchanged, t...
