Problems solved by technology

[0003] It can be seen that when the content of the traditional naked-eye stereoscopic display system is generated, N images need to be generated according to the number of viewing angles (N), and finally an image is synthesized based on the pixel-mapped data, so each frame of image needs to be wasted ((N-1) / N) calculation amount, that is, if the viewing angle is 6, then (5 / 6) calculations are wasted, and the consumption of memory and CPU is considerable

Embodiment Construction

[0028] Such as figure 1 Shown, the present invention a kind of rapid multi-view image synthesis method, it comprises the following steps:

[0029] 1) Data Acquisition: Obtain input image and display parameters;

[0030] 2) Depth map generation: When the input image is a 2D image without a depth map, the depth information of the 2D image is collected to generate a depth map corresponding to the 2D image;

[0031] When the input image is a 2D image and the corresponding depth map, go directly to step 3);

[0032] 3) Establish coordinate relationship: according to the pixel mapping coordinates corresponding to the image to be generated, establish the coordinate relationship corresponding to the image to be generated and the 2D image;

[0033] 3.1) Resolution adjustment: Zoom in / out the 2D image and the corresponding depth map, so that the resolution of the 2D image and the corresponding depth map is the same as the pixel mapping resolution of the display screen;

[0034] 3.2) ...

Abstract

The invention discloses a fast multi-view image synthesis method. According to parameters of a displaying screen and input image content, correspondences of coordinates of images of all view angles and the coordinate of an original 2D image are retroactively calculated through the coordinate of the image of final view angle needed to the produced. The method can omit useless calculation steps, thereby sharply lowering memory requirement and central processing unit (CPU) calculation burden required by image operation; according to experiment results, the CPU calculation burden of a computer adopting the method can be reduced by 30%-35%, and the memory requirement can be lowered by 59-63%.

Description

technical field [0001] The invention relates to an image synthesis method, in particular to a fast multi-view image synthesis method. Background technique [0002] The main difference between the naked-eye stereoscopic display system and the traditional 2D flat display system lies in the lens and content generation. As far as the naked-eye display is concerned, a layer of lenses or gratings is added to the general 2D flat display; and when the content is generated, pictures with different viewing angles are generated according to the viewing angles of the lenses or gratings at the time of design, such as The number of viewing angles of the lens is 6, so when generating content, it is necessary to perform calculations based on depth-based image rendering technology (DIBR) to generate 6 images of different viewing angles, but after generating 6 images of different viewing angles, it is necessary to Or the mapping parameters of the grating are designed to synthesize the last m...
