Abstract
The invention relates to a 2D (two-dimensional)-to-3D (three-dimensional) conversion method. The 2D-to-3D conversion method is characterized by comprising steps of (1), converting the original 2D image in an RGB (red, green and blue) mode into a gray-scale image, and storing the original 2D image and the gray-scale image obtained after conversion; (2), detecting edges of the obtained gray-scale image to obtain edge information of the image, and dividing the image into a foreground layer on inner sides of the edges and a background layer on outer sides of the edges; (3), processing the background layer to generate depth information of the image; (4), converting according to the stored original 2D image to generate a left-eye image and a right-eye image which contain different pieces of depth information; and (5), transmitting the generated left-eye image and the generated right-eye image to a display screen to display the left-eye image and the right-eye image. The 2D-to-3D conversion method has the main advantages that image processing calculation is little under the condition that display effects are equivalent, and accordingly the 2D-to-3D conversion method is easy to implement.
Description
Technical field
The present invention relates to the method that a kind of 2D turns 3D.
Background technology
D is the abbreviation of English Dimension (dimension, dimension), and 3D is exactly the three-dimensional meaning.Compare common 2D picture, 3D is more three-dimensional true to nature, allows spectators that sensation on the spot in person is arranged.Present 3D technology can be divided into two kinds of bore hole formula and spectacles, and bore hole formula 3D technology is mainly used in industrial commercial demonstration aspect at present, and in the display device such as mobile phone; Spectacle 3D technology then is mainly used in consumer level market.Spectacle 3D technology can be divided into three kinds of aberration formula, shutter and polarization types (also being look point-score, time-sharing procedure, light point-score), and bore hole formula 3D technology can be divided into lens arra, barrier fence and point to three kinds of light sources, and the principle of every kind of technology and imaging effect have certain difference.
Summary of the invention
The purpose of this invention is to provide the method that a kind of 2D that is easy to realize turns 3D.
A kind of 2D turns the method for 3D, and its special feature is, comprises the steps:
(1) original 2D image is carried out RGB to the conversion of gray level image, and store the gray level image after original 2D image and the conversion;
(2) gray level image that obtains is carried out rim detection to obtain the marginal information of image, dividing inside, edge is foreground layer, and the outside, edge is the background layer;
(3) the background layer is processed depth information with synthetic image, concrete processing method is that whole display screen is divided into three parts of upper, middle and lower, the upper and lower part accounts for respectively 1/4 of whole display screen, mid portion accounts for 1/2 of whole display screen, background layer segment overall brightness in the upper and lower part is become original 7/8, and the background layer segment overall brightness in middle 1/2 part becomes original 3/4;
(4) carry out conversion according to the original 2D image of storing again, concrete steps are foreground layer and background layers of telling according to rim detection, data to display screen upper and lower part in the background layer multiply by coefficient 7/8, the data of mid portion multiply by coefficient 3/4, thereby generate the right and left eyes image with different depth information;
(5) at last the right and left eyes image that generates being sent to display screen shows and gets final product.
The major advantage of the inventive method is: in the suitable situation of display effect, it is little that image is processed operand, therefore is easy to realize.
Description of drawings
Accompanying drawing 1 is the flow chart of the inventive method.
Embodiment
The inventive method is a kind of Display Technique for glasses shutter 3D, and summary of the invention comprises: image is divided into foreground layer and background layer, and the background layer by changing image generates the right and left eyes image with different depth information.If adopt liquid crystal as the 3D display unit, need liquid crystal to have at least the above refresh rate of 120Hz, the effect that 3D shows just can be more satisfactory.
Embodiment 1:
As shown in Figure 1, to turn 3D algorithm implementation step as follows for 2D:
(1) original 2D image is carried out RGB to the conversion of gray level image, this mainly is to carry out RGB to the conversion of YUV, and stores the gray level image after original 2D image and the conversion;
(2) gray level image that obtains is carried out rim detection to obtain the marginal information of image, dividing inside, edge according to marginal information is foreground layer, and the outside, edge is the background layer;
(3) the background layer is processed depth information with synthetic image, concrete processing method is that whole display screen is divided into three parts of upper, middle and lower, the upper and lower part accounts for respectively 1/4 of whole display screen, mid portion accounts for 1/2 of whole display screen, background layer segment overall brightness in the upper and lower part is become original 7/8, and the background layer segment overall brightness in middle 1/2 part becomes original 3/4;
(4) carry out conversion according to the original 2D image of storing again, here refer to the image of adjusting after the brightness, concrete steps are foreground layer and background layers of telling according to rim detection, data to display screen upper and lower part in the background layer, here refer to brightness data and multiply by coefficient 7/8, the data of mid portion multiply by coefficient 3/4, thereby generate the right and left eyes image with different depth information, be that former data are left-eye image, the above-mentioned data that multiply by behind the coefficient are eye image;
(5) at last the right and left eyes image that generates being sent to display screen shows and gets final product.
Claims (1)
1. a 2D turns the method for 3D, it is characterized in that, comprises the steps:
(1) original 2D image is carried out RGB to the conversion of gray level image, and store the gray level image after original 2D image and the conversion;
(2) gray level image that obtains is carried out rim detection to obtain the marginal information of image, dividing inside, edge is foreground layer, and the outside, edge is the background layer;
(3) the background layer is processed depth information with synthetic image, concrete processing method is that whole display screen is divided into three parts of upper, middle and lower, the upper and lower part accounts for respectively 1/4 of whole display screen, mid portion accounts for 1/2 of whole display screen, background layer segment overall brightness in the upper and lower part is become original 7/8, and the background layer segment overall brightness in middle 1/2 part becomes original 3/4;
(4) carry out conversion according to the original 2D image of storing again, concrete steps are foreground layer and background layers of telling according to rim detection, data to display screen upper and lower part in the background layer multiply by coefficient 7/8, the data of mid portion multiply by coefficient 3/4, thereby generate the right and left eyes image with different depth information;
