In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
In prior art, 3D rendering alignment technique to HUD is to be corrected entire image, it is impossible to pattern distortion is corrected by a point right and left eyes respectively, and then causes only left eye or eye image to be corrected, and the image of another eye causes distortion cumulative, calibration result is poor.3D rendering can form visual interval (also known as " eye case ", the eyebox) of certain area size at eye-observation so that the visual field of right and left eyes is independent, and this provides feasibility for right and left eyes distortion correction.The present embodiment is to correct while right and left eyes distorts to provide a method that, to reach more preferable distortion correction effect, it is achieved good bore hole 3D effect.
Such as Fig. 3 and Fig. 5, in the 3D rendering bearing calibration of this HUD, the HUD related to includes 3D pattern generator 01 and light path adjusting module 02, the light of light path adjusting module 02 output is reflexed to human eye by the reflecting element 03 (windshield or LMDS Light Coupled Device etc.) on automobile, light path adjusting module 02 and reflecting element 03 constitute imaging system, and the image transmitting being used for exporting 3D pattern generator 01 is to left eye and right eye.Such as Fig. 3, this 3D rendering bearing calibration comprises the steps:
In step S101, left eye source images and right eye source images are transformed to respectively left eye predistortion image and right eye predistortion image；Wherein, the image array T2 of left eye predistortion image and right eye predistortion image is: T2=β 0*T0/ β, β is the system imaging amplification of imaging system, it it is a matrix, β 0 is the paraxial imagery amplification of the ideal image system corresponding with imaging system, and T0 is left eye source images and the image array of right eye source images；
In step s 102, left eye predistortion image and right eye predistortion image are exported by 3D pattern generator 01 timesharing, and form left-eye image and the eye image of the distortion that disappears through imaging system.
Specifically, in above-mentioned steps S101, the step that left eye source images and right eye source images are transformed to left eye predistortion image and right eye predistortion image respectively can be completed by a processing module, this processing module can be independently of 3D pattern generator 01, and it inputs 3D pattern generator 01 after left eye source images and right eye source images are transformed to left eye predistortion image and right eye predistortion image respectively；Can also be disposed within this 3D pattern generator 01, carry out conversion by this processing module after left eye source images and right eye source images input 3D pattern generator 01 and obtain left eye predistortion image and right eye predistortion image, then timesharing output.In the method, the distortion occurred after imaging system previously according to left eye source images and right eye source images carries out computing and obtains left eye predistortion image and right eye predistortion image, after this left eye predistortion image and the output of right eye predistortion image, after the transmission of imaging system, form distortionless 3D rendering.
Further, about left eye predistortion image and the acquisition of right eye predistortion image, describe in detail as follows, first understand the 3D picture distortion principle of HUD, produce left eye source images and right eye source images such as Fig. 1,3D pattern generator 01 respectively, light path is extended by plane mirror 021, image is amplified to concave mirror 022 by image transmitting, forms left-eye image 1-L and eye image 1-R after reflecting via windshield, then respectively enter left eye and right eye.By Fig. 1 it appeared that, the image that left eye and right eye are accepted different piece on plane mirror 021, concave mirror 022 and windshield carries out imaging, the most for this reason, the image that right and left eyes is received defines different distortion, its distortion effect is as shown in Figure 2, Fig. 2-a is the image that left eye is seen, Fig. 2-b is the image that right eye is seen.The distortion that left-eye image and eye image produce often is mirrored into relation.
