CN104853177A - Method for automatically generating single image into 3D image - Google Patents

Abstract

The invention relates to a method for automatically generating a single image into a 3D image. According to the method, depth information of the image is extracted through use of a grey-scale map of the single image; after the depth information is processed and extracted by a specific method, the depth information and an original image are combined to generate the 3D image; and an outstanding 3D effect can be seen on a 3D display screen device with an electronic liquid crystal raster. The three-dimensional effect is very good, the screen display effect is remarkable, and within reach view effect is achieved. The method has the advantages of simple operation, convenience and practicability, strong real-time performance, stability and low cost.

Description

A kind of single image generates the method for 3D stereo-picture automatically

Technical field

The present invention relates to the method that single image generates 3D stereo-picture.

Background technology

Current; In stereo video image manufacturing process; 2D-3D conversion, as a kind of three-dimensional implementation, is more and more paid attention to by production of film and TV industry.In the making of stereo-picture; The depth information (depth image) must using image carrys out synthetic stereo image.The usual acquisition degree of depth figureapproach have so several; Utilize multiple point of observation to take pictures to same scenery and obtain multiple image to recover depth information (three-dimensional information), the 3D camera with depth transducer, the non-contact infrared laser radar of object scene.Or the degree of depth drawn by manual intervention figure.It is comparatively complicated that these acquisition processs have.Need special equipment just can obtain.

Summary of the invention

The present invention utilizes the gray scale of 2D single image figureextract the depth information of image.After specific method processing extraction is carried out to these depth informations; With former figurein conjunction with generation 3D rendering; 3D display screen can watch significant 3D effect.Stereoeffect is splendid, goes out to shield Be very effective.Reach the viewing effect making people within reach.The invention has the advantages that simple, convenient and practical, there is real-time, stability, low complex degree, low cost advantage.

application apparatus of the present invention is

The equipment such as the 3D mobile phone having electronic liquid crystal grating 3D to shield/3D panel computer/3D handheld game machine/3D navigator/3D DPF.

Concrete implementation method is the following step:

Be loaded into image;

On the computer with MATLAB software; Image is read in MATLAB software.

Obtain the degree of depth figure;

(1) image converting gradation figure; To gray scale figurecarry out asymmetric Gaussian Blur conversion; Template size is 150X150.Side-play amount is 30 pixels;

(2) Fourier transform is carried out to the image after fuzzy, under frequency domain, enhancing process is carried out to image; Adopt trapezoidal transfer function;

Image pixel value after enhancing is compressed to the scope of-30---30.Can be used as the degree of depth figureuse.

Generate horizontal parallax figure;

(1) the empty matrix of original image size is generated.Be used for filling target image and cause position vacancy because of pixel displacement;

(2) 2 null matrix of original image size are generated; Be used as target image (horizontal parallax figure);

(3) degree of depth of original image element value and neighbor exponential function interpolation+correspondence is used figurethe information of information+empty matrix fills target image (horizontal parallax figure); Horizontal parallax can be obtained figure;

Parallax figureafter synthesis; At the 3D mobile phone/3D panel computer/wait on equipment of 3D screen; The 3D effect of image can be seen.

Above-mentioned steps also can be merged into; Arbitrary picture is loaded into 3D rendering composite software; This picture 3D effect can be watched.
