Left and right disparity map is not obtained, and the display of color value is carried out to pixel each on left and right disparity map；
Left and right disparity map is presented on left and right screen by step E. respectively in real time.
Specifically, in the step B, left and right screen, 3-D image each parallel to two coordinate plane of XY, left and right screen
The midpoint of central point line is origin O (0,0,0)；Distance and the vertical range of right eye R2 to right screen of the left eye R1 to left screen
It is h0, left eye R1 project the point to left screen be S1 (- a, 0,0), right eye R1 project the point to right screen be S2 (a, 0,
0)；3-D image is located at Z axis direction.Further, h0It is preset parameter with a, user can be configured it, by repairing
Change human eye to screen distance parameter or two display screen centre distance parameters, realizes that different user is frequently repaired using when equipment
Change screen relative to position of human eye function, real-time control solid transformation parameter can be required according to individual in 3D conversion process, it is real
Existing individual stereo is shown.
In the step C, the color value of each pixel is indicated by RGB；The coordinate of a certain pixel M in 3-D image
For (x0, y0, z0)。
In the step D, it is based on principle of stereoscopic vision, by pixel M (x a certain in 3-D image0, y0, z0) it is projected to a left side
Point on screen is M1(x1, y1, 0), and by pixel M (x a certain in 3-D image0, y0, z0) it is projected to the point on right screen
For M2(x2, y2, 0)；In the projection plane of left and right screen, M1And M2Coordinate points be converted into space coordinates XYZ and indicate
Are as follows:
M1It is expressed asM2It is expressed as
Using above formula, each pixel in 3-D image is converted respectively, obtains left and right screen 2-D data, shape
At left and right disparity map, and the display on left and right disparity map to each pixel progress color value.
In step E, using threading and pixel array switch technology, in real time by left and right disparity map be respectively sent to it is left,
Right screen output display.
The utility model has the advantages that can realize it in two display screens in the case where not changing original three-dimensional data using this method
True three-dimension scene display in three-dimensional display system, and realized by coordinate where two display screen centre positions of modification
The switching of three-dimensional scenic different angle and direction.
Detailed description of the invention
Fig. 1 is 3-D image coordinate transformation schematic diagram in the present invention.
Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Referring to attached drawing 1, a kind of coordinate transform and display methods of wear-type double screen three-dimensional display system, including following step
It is rapid:
Step A. opens the 3 d image data stored, and reads in the correspondence memory space applied in advance, from
3-D image is got in corresponding memory headroom；
Step B. establishes space coordinates XYZ, defines 3-D image and left and right screen in space coordinates XYZ
Position: each parallel to two coordinate plane of XY, the midpoint of the central point line of left and right screen is original for left and right screen and 3-D image
Point O (0,0,0)；The distance of left eye R1 to left screen is h at a distance from right eye R2 to right screen0, left eye R1 projects to left screen
Point on curtain is S1 (- a, 0,0), and it is S2 (a, 0,0) that right eye R1, which projects the point to right screen,；3-D image is located at Z axis meaning
Direction；
Step C. parses the color value and spatial value of each pixel in 3-D image；Wherein, the face of each pixel
Color value is indicated by RGB；The coordinate of a certain pixel M is (x in 3-D image0, y0, z0)；
Step D. is projected to left and right screen according to the spatial value and each pixel of pixel each in 3-D image
Coordinate value obtains left and right disparity map respectively, and the display of color value is carried out to pixel each on left and right disparity map；
Method particularly includes: it is based on principle of stereoscopic vision, by pixel M (x a certain in 3-D image0, y0, z0) it is projected to a left side
Point on screen is M1(x1, y1, 0), and by pixel M (x a certain in 3-D image0, y0, z0) point that is projected on right screen is
M2(x2, y2, 0)；In left and right screen prjection plane, M1And M2Coordinate points be converted into space coordinates XYZ and indicate are as follows:
M1It is expressed asM2It is expressed as
Using above formula, each pixel in 3-D image is converted respectively, obtains left and right screen 2-D data, shape
At left and right disparity map, and the display on left and right disparity map to each pixel progress color value；
Step E. uses threading and pixel array switch technology, and left and right disparity map is respectively sent to left and right in real time
Screen output display.
Further, h described in step B0It is preset parameter with a, user can be configured it, by modifying human eye
To screen distance parameter or two display screen centre distance parameters, screen is frequently modified when realizing different user using equipment
Relative to position of human eye function, real-time control solid transformation parameter can be required according to individual in 3D conversion process, realizes individual character
Change stereoscopic display.
