Embodiment 1

[0018] A method for converting 2D to 3D based on image segmentation technology, comprising the steps of:

[0019] (1) Receive the original 2D image and cache the first frame data;

[0020] (2) Cache the next frame of data;

[0021] (3) Extract the unoutputted last frame data, and calculate the gray value of each pixel in the image;

[0022] (4) arrange the gray values ​​of all pixels in ascending order and store the result;

[0023] (5) Set the standard gray value h (h is set by the internal data summary, in this example, the arithmetic mean of the gray value of all pixels is used), and mark the pixels smaller than h and larger than h, which is equal to h The pixels of are not marked, and the marked results are cached;

[0024] (6) Separate the pixels with a gray value greater than h from left to right, and move n pixels to the left or n pixels to the right (n can be set according to the depth of field requirements, in this example, move to the right by 192 pixels), to obt...

Abstract

The invention relates to a method for realizing 2D-to-3D (two-dimension to three-dimension) conversion based on an image segmentation technology. The method is characterized by comprising the following steps of: (1) receiving original 2D images and buffering first frame data; (2) buffering next frame data; (3) extracting non-output previous frame data and calculating the gray-scale value of each pixel of the images; (4) sequencing the gray-scale values of all pixels in an ascending order and saving a result; (5) setting a standard gray-scale value h; (6) carrying out left-and-right separation on the pixels with the gray-scale values greater than h; and (7) respectively outputting left-eye images and right-eye images to a display screen in a timesharing manner. According to the method disclosed by the invention, the gray-scale value of each pixel is extracted, the sequencing is carried out according to the gray-scale values, the fixed gray-scale value h is taken as a demarcation criterion of the sequenced result, image contours are determined, the left-eye images and the right-eye images are separated on the basis that the contours are known, and shutter-type 3D glasses are used in a matching manner, thus the 3D effect is realized.

Description

technical field [0001] The invention relates to a method for realizing 2D to 3D conversion based on image segmentation technology. 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...
