Embodiment Construction

[0032] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.

[0033] 1. Glasses-free 3D display

[0034] Glasses-free 3D display technology starts from the display device, adding a layer of barrier or lens in front of the display screen, so that the left and right eyes can see 2D images with a certain parallax, so that depth perception can be produced without wearing auxiliary equipment.

[0035] Glasses-free 3D display technology can be divided into parallax barrier display technology, lenticular lens display technology, multi-layer display technology and holographic technology according to its display characteristics and optical str...

Abstract

The invention discloses a multi-view image fusion method based on a floating-point type cylindrical lens grating. Based on the prior art, for the coefficient array generation, firstly, multiplication and division are adopted and then complementation is carried out, and then the calculation of the rows and columns is deformed, therefore, the number of the complementation can not only be reduced, but also the multiplication of floating-point type data in the calculation after the deformation can be reduced, and the amount of calculation is less. On a formula after rows and columns deformation, the complementation is converted, there is no complementation for the floating-point type data in hardware, and a comparator converts the operation into an addition and subtraction capable of being realized by the hardware; and at the same time, when collecting image sub-pixels, each sub-pixel in a fusion image is derived from two different viewpoints, and each viewpoint accounts for a different proportion, thus sub-pixel acquisition and weighting are performed on multiple views and then the views are fused into a glass-free 3D image suitable for the display of the floating-point type cylindrical lens grating, thereby saving more hardware resources while guaranteeing the precision.

Description

technical field [0001] The invention belongs to the technical field of glass-free 3D display, and more specifically relates to a multi-viewpoint image fusion method based on a floating-point lenticular lens grating. Background technique [0002] Glasses-free 3D display, also known as autostereoscopic display, is based on the principle of utilizing the parallax or disparity characteristics of human beings so that the viewer can directly view the naked-eye 3D display without using auxiliary equipment such as 3D glasses. Display devices such as display screens can perceive and experience three-dimensional depth of field. Generally speaking, the larger the display size and the higher the resolution, the more shocking the glasses-free 3D display will be. The UHD display has a resolution of 3840×2160. In order to increase the range of viewing angles and enhance the effect of 3D display, views from multiple viewpoints are usually required. According to the requirements of the di...
