Embodiment 1

[0024] like figure 2 As shown, it is a flow chart of the method for realizing the 2D to 3D conversion by the weighted average operator algorithm, including the following implementation process:

[0025] 1) Receive the original 2D image from the video source, and cache the first frame data. Considering the size of the image, it is calculated with 1920*1080*32bit data volume, and it is necessary to ensure that the cache space has at least 70Mbits of space;

[0026] 2) Continue to receive the next frame of data and cache the next frame of data, and also ensure that the cache space must be at least 70Mbits;

[0027] 3) Extract the first frame data from the cache;

[0028] 4) Calculate the offset position of the pixel with reference to the formula (y*w+x)*4, where (x, y) represents the horizontal and vertical coordinates of the pixel point in the image, and w represents the width of the image;

[0029] 5) According to the Sobel edge operator algorithm to calculate the gray level...

Abstract

The invention relates to a method for achieving 2D-3D conversion based on weighted average operator algorithm. The method is characterized by comprising the following steps: (1) receiving an original 2D image and caching data of a first frame; (2) caching data of the next frame; (3) extracting the data of the first frame; (4) calculating the offset position of each individual pixel of the first frame image; (5) calculating gray scale difference of each individual pixel field based on the weighted average operator algorithm; (6) generating edge scan result of each pixel and determining whether the processing of all pixels is completed or not; (7) dividing images displayed by left and right eyes according to an edge scan grayscale; (8) caching the divided two images according to time sharing order; and (9) outputting a first frame for displaying and returning to the step (2) for performing so long as the data of the next frame arrives. According to the method provided by the invention, characteristics of surrounding pixel points are considered comprehensively when the gray scale difference of each individual image is calculated, so that the edge outlines of the generated images are smoother.

Description

technical field [0001] The invention relates to a method for converting 2D to 3D based on a weighted average operator algorithm. Background technique [0002] At this stage, 3D technology is developing at an extremely fast speed. As people pay more attention to 3D technology, more and more manufacturers launch new products that support 3D display. 3D TVs, 3D projectors, 3D mobile phones, 3D portable video players, etc. are gradually entering the homes of ordinary people. However, due to the number of 3D film sources, most devices that support 3D display often cannot give full play to its role. Because of this, the technology of converting traditional 2D video into 3D video has attracted the attention of various manufacturers. [0003] For the original 2D image or video, if you want to convert it into an image suitable for 3D display, you need to separate the left-eye and right-eye images from the original image, and process the left-eye and right-eye images in different w...
