Twill grating three-dimensional original image filling method based on matching weighting

Abstract

The invention discloses a twill grating three-dimensional original image filling method based on matching weighting, and belongs to the technical field of naked eye 3D display. According to the method, in the synthesis process of a three-dimensional original image, filling of fractional sub-pixels is improved, specifically, the relation between an object to which a full pixel where the sub-pixelslocated at the serial number of a fractional viewpoint image belong and an object to which adjacent viewpoint pixels belong is judged through pixel matching, and then inverse distance weighted fillingis selected to be used; compared with an existing method, the three-dimensional original image generated through the method has the advantages that under the effect of the twill grating, the image roughness is obviously improved, the image is more delicate, details are better, the crosstalk phenomenon is restrained, and the false 3D effect caused by too much crosstalk when parallax is small 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
