[0020] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the text of the description.

[0021] Such as figure 1 As shown, the present invention provides a method for converting 2D to 3D, which includes the following steps:

[0022] Step 1: Obtain a 2D image, and perform grayscale processing on the 2D image to obtain a grayscale image;

[0023] Step 2: Perform edge detection on the grayscale image to obtain an image contour.

[0024] Step 3. Calculate the depth values ​​of all pixels in the grayscale image, calculate the average value of the depth values ​​between all pixels within the image contour in the grayscale image, and calculate the grayscale based on the first average value described above The first average difference of the depth values ​​of all pixels within the image contour in the image.

[0025] In general, the part within the image outline is als...

Abstract

The invention discloses a 2D (Two Dimensional) to 3D (Three Dimensional) conversion method. The 2D to 3D conversion method comprises the following steps of: pre-processing a grayscale image to a certain extent before calculating a depth map; dividing the grayscale image into a plurality of blocks according to a certain rule; obtaining the depth maps of the plurality of blocks and combining the depth maps to obtain the depth map of the whole 2D image. The 2D to 3D conversion method can be used for obtaining a good conversion effect.

Description

technical field [0001] The invention relates to the field of computer video processing, in particular to a method for converting 2D to 3D. Background technique [0002] Compared with ordinary 2D pictures, 3D is more three-dimensional and realistic, which can make the audience feel immersive. At present, 3D technology can be divided into two types: naked-eye type and glasses type. At present, the naked-eye type 3D technology is mainly used in industrial and commercial display, while the glasses-type 3D technology is mainly used in the consumer market. [0003] The video processing method of 2D to 3D technology usually first obtains the grayscale image of the 2D image, and then processes the grayscale image to obtain the depth map of the entire 2D image. There are currently many ways to generate the depth map, and its generation quality will also affect transition effect. Contents of the invention [0004] In view of the above technical problems, the present invention prov...
