The second support arm and third support arm and drive the second support arm to move up and down third driving device -6, be fixed on third
Support arm and master arm and fourth drive device -6, camera and the attitude transducer for driving third support arm to move left and right
And controller.
The control system uses pure closed loop design, and wherein main processing controller is controlled using miniature PC machine.Firstly, user
Before using display, study switch is pressed, and set standard and correctly use posture, at this moment camera will capture human face
Characteristic information, pupil relative position information and relative position of other positions of body with respect to computer monitor and distance, hold
Continuous 5 to 8 seconds time, the image data of camera acquisition and the location information data of relative position are stored in miniature PC machine
On.
During user's use, camera acquires always user's pupil image data and relative position in real time
Location information data, and compared with the location information data of the pupil image data and relative position that learn before
It is right, a steady state error range is set, if the result that processor processes information obtains among this steady state error range, then
Controller will not make any movement.
User using computer for a period of time after, it may appear that tired state.At this point, user will adjust sitting posture into
Row rest, but after the sitting posture that user adjusts itself, if adjusting the position of oneself display not in time, at this moment
If reviewing display, it will be inappropriate sitting posture, lead to the problems such as eyesight, vertebra, cervical vertebra occur, human body is caused
Great damage.
This is that the location information data of the image data that camera acquires back and relative position can be obtained with study before
Image data and relative position location information data error it is very big, exceed steady-state error range.Controller control at this time
System first, second, third and fourth drive device drive each support rod to adjust position, and camera adjusts position in controller
During user's face pupil information and other physical feeling key messages are acquired, signal is transferred to controller,
Carry out pictorial information processing.
It during control adjustment, is mainly adjusted using dynamic self-adapting PID, and is corrected with Coleman filtering,
The feedback of correction link issues processor analysis again.Until the position when display screen reaches normal range, controller stops band
The movement for moving first, second, third and fourth drive device, reaches and just reaches entopic purpose again.
When controller is in automatic mode, the people of camera meeting automatic identification display visible area starts face mould
Paste identifying system;If current one-man, controller can according to where face position control first driving device, second
Driving device, third driving device and the 4th starter adjust automatically up and down, the angle and distance of left and right and front and back;If it is
More people are in the visible area of display, select central point and calculate to need to adjust to control two farthest people according to Fuzzy Calculation
Whole data information, and control first driving device, the second driving device, third driving device and the 4th starter and adjust automatically
Whole upper and lower, left and right and front and back angle and distance, every time when detecting that human face position changes, delay is adjusted for 2-3 seconds
It is whole, to prevent from rotating frequently.
In the detection process, it may appear that user leaves seat, and perhaps rotary head takes thing or reading etc. of writing of bowing, this
When display screen there is no fear of the movement with user, at this moment just realized using pupil tracing technology and swept when camera can be seen
When retouching pupil information, just carry out as adjustment, when the pictorial information kind that camera scans can not capture pupil of human position,
It is so just slack.
The above process details the working principle and mechanical structure of a kind of intelligent follow-up adjusting display bracket, but the present invention
It is not limited to the above embodiments, a variety of variations, all skills according to the present invention can be made with the purpose of innovation and creation according to the present invention
Change, modification, substitution, combination or the simplification made under the Spirit Essence and principle of art scheme, should be equivalent substitute mode, only
Meet goal of the invention of the invention, without departing from the technical principle and invention of present invention automatic adjustment range display bracket
Design, belongs to protection scope of the present invention.
