Embodiment 1

[0032] see image 3 , the invention discloses a method for synthesizing multi-viewpoint stereoscopic images. The arrangement of multi-viewpoint stereoscopic images consists of a front view area and an inversion area, and the front view area is larger than the inversion area.

[0033] Let the number of viewpoints of the naked-eye 3D display device be N d , the number of viewpoints in the emmetropic area is N s , the number of viewpoints in the inversion zone is N i , then N s >N i and N d =N s +N i .

[0034] The naked-eye 3D display device includes a display device and a grating device; the viewpoint number corresponding to the display pixel or sub-pixel of the display device Among them, W p is the width of the display pixel or sub-pixel, W a is the tilt offset of each row of the raster, W d is the sum of the widths of several pixels or sub-pixels corresponding to the raster unit, m is the row number of the pixel or sub-pixel, and n is the column number.

Embodiment 2

[0039] see Figure 5 , in this embodiment, a pixel is used as a basic display unit, such as an LED display screen. Let W p = 1, W a = 1 / 3, W d=5, then the number of viewpoints of the naked-eye 3D display device is 15, and the number of multi-viewpoint stereoscopic images with 13 images is used, then the number of viewpoints in the front view area is 13, and the number of viewpoints in the reverse area is 2, V0, V1,..., V14 are the devices Pixel viewpoint numbers, I0, I1, ..., I12 are multi-view stereo image viewpoint image signals. This embodiment can obtain a better visual effect, the transition of the viewing area is smooth and the ghost vision is invisible, such as Figure 5 shown.

Embodiment 3

[0041] see Image 6 , in this embodiment, a sub-pixel is used as a basic display unit, such as an LCD display screen. Let W p = 1, W a = 1 / 2, W d =16 / 3, then the number of viewpoints of the naked-eye 3D display device is 32, and the multi-viewpoint stereoscopic image with the number of images of 25 is used, then the number of viewpoints in the front viewing area is 25, and the number of viewpoints in the inversion area is 7, V0, V1,...,V31 I0, I1, ..., I24 are multi-viewpoint stereo image viewpoint image signals. This embodiment can obtain a better visual effect, the transition of the viewing area is smooth and the ghost vision is invisible, such as Image 6 shown.

Abstract

The invention discloses a method for synthesizing multi-viewpoint stereoscopic images, comprising: the arrangement of multi-viewpoint stereoscopic images is composed of a front view area and an inversion area, and the front view area is larger than the inversion area. Let the number of viewpoints of the naked-eye 3D display device be N d , the number of viewpoints in the emmetropic area is N s , the number of viewpoints in the inversion zone is N i , then N s >N i and N d =N s +N i . Viewpoint number corresponding to the display pixel or sub-pixel of the display device in the naked-eye 3D display device Among them, W p is the width of the display pixel or sub-pixel, W a is the tilt offset of each row of the raster, W d is the sum of the widths of several pixels or sub-pixels corresponding to the raster unit, m is the row number of the pixel or sub-pixel, and n is the column number. The method for synthesizing multi-viewpoint stereoscopic images proposed by the present invention can solve the problem of ghosting and improve the problem of viewing zone shear, especially on naked-eye 3D display devices using similar ultra-multi-viewpoint display technologies.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a stereoscopic image synthesis method, in particular to a multi-viewpoint stereoscopic image synthesis method. Background technique [0002] The naked-eye 3D display device is composed of a display device and a grating device. The grating device is usually arranged obliquely and a single grating unit corresponds to several display pixels or sub-pixels; multi-viewpoint stereoscopic images are synthesized and displayed on the naked-eye 3D display device to make the viewer feel to the stereoscopic effect. [0003] There are already many multi-viewpoint stereoscopic image synthesis methods, such as the patent (publication number CN101175223) applied by Tianjin University, the patent (publication number 102708577) applied by Zhonghang Huadong Optoelectronics Co., Ltd., etc. The common feature of these methods is that the multi-viewpoint stereoscopic image is sequentially period...
