Abstract
The utility model relates to a naked eye tridimensional display with all round looking function. The display is characterized in that an eye positioning and tracking sensor is connected with a computer which is connected with the naked eye tridimensional display. The utility model has the advantages that: firstly, the naked eye tridimensional displays of two sub screen sections can also realize the all round looking function according to the distribution of independent optic zones; secondly, the demarcation cross section pictures of the independent optic zones are used to form images in the CCD view field, and the pixel coordinate of the independent optic zones are marked; thirdly, under the help of the identifying and tracking function of the CCD eye, the position of the eye in the view field can be gotten, and the specific viewpoint of the eye in the naked eye tridimensional display can be justified accordingly.
Description
Technical field
The utility model relates to a kind of naked-eye stereoscopic display with the function of looking around.
Background technology
For three-dimensional display, pursuit be to demonstrate stereo scene truly, naturally, reach similar viewing effect of being in the action.This effect also show as can be very natural when watching scenery from different perspectives the position relation that they exist in the objective world of seeing, when promptly eye position moves, can see the side of scenery.This display technique is called multi-viewpoint three-dimensional and shows (Multi-view), also can be called and look around stereo display (Look-around).
The inferior screen of naked-eye stereoscopic display has formed the non-interfering independent vision area of right and left eyes view through the separation and the convergence of optical element, they are positioned at a distance, display the place ahead, each inferior screen has formed a plurality of independent vision areas, and independent vision area becomes certain included angle with the normal direction of display.Adjacent independent vision area is divided into several groups by the corresponding relation of they and inferior screen, and every group forms a viewpoint, and each independent vision area is corresponding to a virtual screen like this, and the right and left eyes independence vision area of space has formed several viewpoints.
Present multi-viewpoint three-dimensional display uses the form of a plurality of inferior screen partitions.For example utilize post lens method to make many group views can produce corresponding independent vision area, thereby reach many viewpoints Presentation Function by the order of inferior screen arrangement.
Realization principle based on the naked-eye stereoscopic display of TFT LCD has determined the human eye viewing location to be limited in certain zone, and people's head can only be moved in limited scope.However, the characteristic distributions of independent vision area also makes the multi-angle of naked-eye stereoscopic display observe becomes possibility.
Summary of the invention
The purpose of this utility model provides a kind of naked-eye stereoscopic display with the function of looking around.It can realize looking around function, behind increase by the one cover human eye recognition and tracking device, in conjunction with the distribution characteristics of independent vision area, promptly can reach many viewpoints effect.
The utility model is achieved like this, it comprises naked-eye stereoscopic display, three-dimensional to video image, eye location tracking transducer, eye position analysis and computing machine, it is characterized in that: the eye location tracking transducer connects computing machine, and computing machine connects naked-eye stereoscopic display.By looking around multi-angle solid that video camera obtains in the video image input computing machine, the eye location tracking transducer is imported computing machine through the eye position analysis with information, computing machine is handled video image solid, image after the processing enters naked-eye stereoscopic display, realizes that through the naked-eye stereoscopic display of the inferior screen of images of left and right eyes many viewpoints show.
The utility model has the advantages that: (1) according to the distribution situation of independent vision area, the naked-eye stereoscopic display of 2 inferior screen partitions also can realize looking around function, and the principle of realization is to cooperate human eye vision to follow the tracks of and pick-up unit; (2) use the imaging of independent vision area boundary sectional view in the CCD visual field, calibrate the pixel coordinate of independent vision area, thereby can obtain viewing distance according to the imaging of eyes in CCD; (3) use identification of CCD eyes and following function, can obtain the position of eyes in the visual field, and differentiate the concrete viewpoint that eyes are positioned at naked-eye stereoscopic display in view of the above.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the drawings, 1, naked-eye stereoscopic display 2, three-dimensional to video image 3, computing machine 4, look around multi-angle solid that video camera obtains to video image 5, eye location tracking transducer 6, eye position analysis
Embodiment
The utility model comprises naked-eye stereoscopic display 1, three-dimensional to video image 2, eye location tracking transducer 5, eye position analysis 6 and computing machine 3, it is characterized in that: eye location tracking transducer 5 connects computing machine 3, and computing machine 3 connects naked-eye stereoscopic display 1.By the multi-angle solid that eye location tracking transducer 5 obtains video image 4 is imported in the computing machines, the eye location tracking transducer is imported computing machine 3 through eye position analysis 6 with information, computing machine is handled video image 2 solid, image after the processing enters naked-eye stereoscopic display 1, realizes that through the naked-eye stereoscopic display of the inferior screen of images of left and right eyes many viewpoints show.
Claims (1)
1. naked-eye stereoscopic display with the function of looking around, it comprises naked-eye stereoscopic display, eye location tracking transducer and computing machine, it is characterized in that: the eye location tracking transducer connects computing machine, and computing machine connects naked-eye stereoscopic display.
