Specific embodiment
In the description of the present invention, it is to be understood that if there is the orientation of the instructions such as term " on ", " under ", "left", "right"
Or position relationship is based on orientation shown in the drawings or position relationship, is for only for ease of the description present invention and simplifies description, and
It is not instruction or implies signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore
The terms describing the positional relationship in the drawings are only for illustration, it is impossible to the limitation to this patent is interpreted as, for this field
Those of ordinary skill for, can understand the concrete meaning of above-mentioned term as the case may be.
Reach the technological means and effect that predetermined purpose taken for the present invention is further explained, below in conjunction with attached drawing and reality
Example specific embodiment, structure feature and its effect to the present invention are applied, detailed description are as follows.
A kind of intelligent elevated display as Figure 1-Figure 2, display 1 and the lifting dress for being arranged on 1 lower section of display
It puts, further includes image acquisition and processing device, image acquisition and processing device includes CCD camera 2, infrared light-emitting diode 3, timer
4 and microcontroller 5, CCD camera 2 and infrared light-emitting diode 3 are arranged on 1 top of display；CCD camera 2 is interactive with microcontroller 5
Connection, the input terminal of infrared light-emitting diode 3 are connected with the output terminal of microcontroller 5, output terminal and the microcontroller 5 of timer 4
Input terminal is connected.Angle based on sight can be detected the sight of human eye, when being irradiated to people with an infrared auxiliary light source
Face when, form reflection image in the anterior corneal surface of eyes, this reflection image is referred to as Purkinje image point.In presumptive test person's head not
In the case of dynamic, since the position of infrared light-emitting diode is changeless, and eyeball is an approximate sphere, works as eyeball
During rotation, it is believed that the absolute position of Purkinje image point is constant, and the position of iris and pupil will occur to become accordingly
Change, the Purkinje image point and the relative position relation of pupil that can be formed in this way by infrared auxiliary light source in iris judges to regard
Line direction.Since the gray value of pupil is minimum, and the gray value of Purkinje image point is maximum, so carrying out threshold value to eyes image
After processing, it is easy to the relative position relation of pupil and Purkinje image is found, so as to conclude direction of visual lines.When head, generation is small
It is necessary to establishing direction of visual lines update the system during rotation.
Lifting gear includes babinet 6, is equipped with rack 7 and decelerating motor 8 in babinet 6, decelerating motor 8 passes through motor gear 9
It is connect with rack 7；The motor gear 9 of decelerating motor 8 is engaged with rack 7；The input terminal of decelerating motor 8 and the output of microcontroller 5
End is connected；The both sides of rack 7 are respectively equipped with a slide-and-guide bar 10, are set on each slide-and-guide bar 10 there are one sliding block 11,
Two sliding blocks 11 are connected by bracket 12；Bracket 12 is connected with rack 7, and bracket 12 is equipped with firm banking 13, firm banking 13
It is connected with display 1, timer 4 is arranged on firm banking 13.When microcontroller 5 sends out execute instruction to decelerating motor 8, subtract
Speed motor 8 is started to work, and motor gear 9 is driven to move and then moved with carry-over bar 7, and bracket 12 is lifted, to reach adjustment
The effect of 1 height of display.When rack 7 lifts, sliding block 11 slides up and down on slide-and-guide bar 10, so as to which bracket 12 can be with
Stable lifting has achieved the effect that display 1 stablizes lifting.
