The influence of body display effect.
As the further improvement of above-mentioned embodiment, as shown in Fig. 1, Fig. 3 and Fig. 4, it is special that signature identification 33 includes image
Sign, characteristics of image can be traced unit identification.Tracking cell traces into characteristics of image, and it is anti-that 3 d display device 1 will track signal
Feed control device 2.For control device 2 according to tracking signal, control image acquiring device 3 obtains what 3 d display device 1 was shown
Stereo-picture.Using installed part 31 instead of using person, 3 d display device 1 is according to the position adjustment stereoscopic display of signature identification 33
Content, thus, in actual use, it can enable a viewer to watch stereoeffect incessantly, and watch interior
Appearance can make corresponding change according to the orientation and movement tendency of user, realize the interaction of user and display content, improve vertical
The sense of reality that body is shown.
Certainly, the signature identification 33 that present embodiment provides is not limited only to characteristics of image, can also be it is raised or other
Unit can be traced and know another characteristic.
As the further improvement of above-mentioned embodiment, characteristics of image include face characteristic, character feature, graphic feature with
And the one or more in color characteristic.Using face characteristic, instead of using person, the viewing environment of user is simulated, acquisition
Correction parameter is more pressed close to truly.Certain characteristics of image can also be other features, as long as the feature that tracking cell can recognize that should
It is within the scope of the present invention
Such as Fig. 1, Fig. 3 and to shown in Fig. 5, image acquiring device 3 includes at least one camera 32, and camera 32 is arranged on
At position of human eye, the stereo-picture of the shooting display of 3 d display device 1.In the present embodiment, camera 32 is set including interval
The left camera 32a and right camera 32b put, left camera 32a and right camera 32b structures, physical property are all identical, and a left side is taken the photograph
As the spacing between head 32a and right camera 32b can be regarded as human eye interpupillary distance, meet three-dimensional imaging requirement.3 d display device 1
The stereo-picture of change is shown, left camera 32a and right camera 32b are shot to 3 d display device 1 simultaneously, left shooting
Head 32a shooting stereo-pictures obtain the first image change, and right camera 32b shootings stereo-picture obtains the second image change.Control
Device 2 processed is handled the first image change and the second image change respectively, is obtained and is met default bar in the first image change
The left view graph parameter of part, and meet the right view parameter of preparatory condition in the second image change.Control device 2 combines left view
Parameter, right view gain of parameter meet the correction parameter of preparatory condition.When user shows stereogram using 3 d display device 1
During picture, rigging error is corrected according to correction parameter, the stereo-picture of display influences display effect not without crosstalk, moire fringes etc.
Good factor, good display effect is obtained, the problem of elimination because of rigging error influence stereo display effect.Compared to existing skill
Art, the correction subsystem 200 that present embodiment provides can obtain the correction parameter of 3 d display device 1,3 d display device 1
