Abstract
The invention relates to a zooming 3D (third-dimensional) display technique and aims to a zooming visual effect for spatial senses of human eyes. Specifically, relative positions of corneas of left and right eyeballs in the white parts of eyes are located through at least one camera, and a sight line intersection is calculated accordingly; a filter is used to perform different-level fuzzing to objects, different in distance, in a visual scene according to the position of the sight line intersection; in a 3D display, a fuzzed 3D image is displayed to simulate the eyes zooming in the reality. The zooming 3D display technique has the advantages that few hardware devices are required, only the cameras for measuring the angle of eyeball are added, the cost is low, and popularization is easy.
Description
Technical field
The present invention relates to a kind of zoom 3D display technique, belong to 3D and show field.This technology, in 3D Presentation Function, with the addition of vision zoom function, can coordinate 3D display device, for user provides more real visual experience.
Background technology
The space sense of human eye is derived from the parallax between right and left eyes, is called: disparity space sense; And lenticular zoom, be called: zooming space sense.
Existing 3D display technique utilizes principle of parallax, for user provides disparity space sense, and have ignored the impact of vision zoom on space sense.Therefore existing 3D display technique is actually a kind of " focusing 3D display technique ", space sense that can not be complete in simulating reality environment.
Such as 3D display screen and wear-type 3D display.The former is by microstructure (polariscope or grating) two width anaglyphs about same display screen display in display screen, and the sight line focus of user is limited on display screen present position.Wear-type 3D display left right eye projects anaglyph respectively, and image scioptics form a virtual image drawing axis about 3 meters, and the sight line focus of user is limited on virtual image present position.These two kinds of 3D display devices all do not consider vision zoom.
And 3D shows in practical application, particularly in 3D game, user frequently switches sight line focus, observes visual scene and nearby at a distance.Traditional focuses 3D display technique, does not distinguish focal length difference and nearby at a distance, the false visual experience caused.
The present invention proposes a kind of zoom 3D display technique, on the basis that parallax 3D shows, simulate the visual effect that crystalline lens zoom is formed, for user provides truer 3D visual experience.
Summary of the invention

7., after using obfuscation filter that the scenery outside field depth is carried out Fuzzy processing, be projected on the left and right two width image containing parallax;
8. above-mentioned anaglyph is shown on 3D display device;
9. above-mentioned step is carried out with the speed loop of 30 ~ 120 times per second, and the refresh rate of its speed and display device matches.
Another technical scheme of the present invention is above-mentioned 3D display device is 3D display screen or wear-type 3D display.
When another technical scheme of the present invention is applied to wear-type 3D display on being, described camera is fixed on head-mounted display, is positioned at eyes front upper place, front lower place or outside.
The present invention proposes zoom 3D display technique, the basis of existing 3D display device has been reproduced " the zooming space sense " in eye space perception, eliminate the false visual experience focused in 3D display technique shown in Fig. 4, complete 3D visual experience can be provided for user.
advantage of the present invention
Hardware device required for the present invention is few, increase only the camera that is measured eyeball angles, has cost low, the advantage easily promoted.

The realization flow figure that Fig. 1 is technology described in this patent;
The equipment of Fig. 2 needed for specific embodiments and arrangenent diagram;
Fig. 3 is human eye vision zoom principle schematic;
Fig. 4 is the Contrast on effect that tradition focuses 3D display (a be left-eye image, b be right eye) and zoom 3D of the present invention display (c be left-eye image, d be right eye).
Embodiment
A kind of zoom 3D display technique that the present invention proposes.When being applied to wear-type 3D display, embodiment as shown in Figure 2:
The equipment needed:
1) display device adopts wear-type 3D display 3, is commonly called as " 3D video eyeglasses ".
2) two cameras 2, be placed in right and left eyes front upper place, is fixed on wear-type 3D display 3.
3) for providing the host computer 1 of image source and process 3D rendering.
4) the downlink data line 4 of 3D rendering after transmitting zoom process by host computer to wear-type 3D display; With the upstream data line 5 being transmitted left and right eyeball image by camera to host computer.
Workflow:
First by the camera acquisition eyeball image 6 being positioned at drawing axis, search for the circular dark areas that cornea is corresponding in eyeball image, determine the side-play amount 7 of cornea in the white of the eye, right and left eyes is respectively:
d l ,
d r ; And right and left eyes interpupillary distance 11, be denoted as
