A Method for Filling Twill Grating Stereo Original Image Based on Matching Weight

Abstract

The invention discloses a method for filling a twill grating stereoscopic original image based on matching weighting, and belongs to the technical field of naked-eye 3D display. The method of the present invention improves the filling of fractional sub-pixels in the process of synthesizing the stereoscopic original image. Specifically, through pixel matching, the object to which the full pixel of the sub-pixel located at the fractional viewpoint image number is located and the object to which the adjacent viewpoint pixel belongs are compared. judge the relationship between them, and then choose to use inverse distance weighted filling, or the method of rounding to the nearest to obtain the value of the sub-pixel. Compared with the existing method, the stereoscopic original image produced by the method of the present invention is rough under the effect of the twill grating. The sense of vision is significantly improved, the picture is more delicate and the details are better, the crosstalk phenomenon is suppressed, and the false 3D effect caused by too much crosstalk due to small parallax is reduced.

Description

technical field [0001] The invention belongs to the technical field of naked-eye 3D display, and more particularly relates to a method for filling a twill grating stereo original image based on matching weighting. Background technique [0002] In the field of 3D displays, due to the relatively expensive foreign equipment, the market demand is small, so it is very necessary to reduce the cost of equipment to reduce the selling price in exchange for market potential. However, China is still in its infancy. Although many manufacturers have developed glasses-free 3D displays produced on a certain scale, their effects have not reached the level of foreign countries. [0003] The naked-eye 3D display based on the lenticular lens grating, that is, the lenticular lens grating is assembled on the display plane, has the characteristics of obtaining a good 3D look and feel without wearing peripheral equipment, and is more suitable for the current market demand. The basic principle of ...

Problems solved by technology

[0004] However, in the stereoscopic original image required for the production of naked-eye 3D displays based on twill lenticular gratings, due to the limitation of the slant characteristics of twill gratings, it is possible to obtain fractional viewpoints after substituting its parameters into the sub-pixel mapping formula

Fractional viewpoints mean that a sub-pixel will be mapped to different viewpoints, resulting in blurred images with ghosting and deepening crosstalk, and due to the incorrect mapping of fractional sub-pixels, most of the edge details of the image will be lost, causing naked-eye 3D display effect is not satisfactory
