A kind of multi-touch display system based on graphene optical sensing technologyTechnical field
The present invention relates to multi-touch display system field, more particularly to one kind based on graphene optical sensing skillThe multi-touch display system of art.
Background technology
With the development of electronic information technology and network technology, multi-point touch system shows as a kind of real-time interaction systemShow the convenience because of its operation, flexibility, be able to the extensive use in each field.
At present, multiple point touching Display Technique is mainly infrared technique using technology, using infrared-type touching technique sexual valenceCompare it is high, will not be by electric current, voltage and electrostatic interference, response speed is faster but redder than conventional condenser touching techniqueOuter formula touch display screen is easily influenceed by tiny exotic and produces error, its performance of image, more suitable for environmentPreferably, without infrared ray and all kinds of places of light interference are robbed, to touch more brisk smoothness, reduces external environment condition and multiple spot is touchedTouch the influence of effect, optical touch technology starts to obtain larger range of research and development and application, using optical image touching technique,Realize that multiple point touching and various gestures identify by optical image touching technique, effectively improve display screen touch sensitivity,The optical image touching technique used at present, which needs 2-4 camera to coordinate, could effectively realize multiple point touching effect, and withThe development of technology and the research and development of new material and application, searching can make the more sensitive sensing technology equipment of touch display systemWith quick-reaction system, production cost is reduced, turns into the Research Emphasis for meeting market needs.
The content of the invention
It is an object of the invention to solved by a kind of multi-touch display system based on graphene optical sensing technologyThe problem of certainly background section above is mentioned.
To achieve the above object, the present invention uses following technical scheme.
A kind of multi-touch display system based on graphene optical sensing technology, including two motion capture modules, oneIndividual intelligent image processing system, an intelligent display system.
The motion capture module is embedded on the intelligent display system, light sensation camera built in motion capture module,And high dependent sensor is connected, the high dependent sensor is using composite graphite alkene sense film as pedestal, to improve the photosensitive of picture catchingDegree and sensitivity.Operating gesture before the intelligent display system is caught from different perspectives by described two light sensation cameras, is led toThe high dependent sensor is crossed to transmit the action captured variation signal to the intelligent image processing system.The graphene movesMaking capture module can freely install, dismantle, and be matched with the intelligent image processing system employing wireless, use is more convenient.
The intelligent image processing system carries out intellectual analysis for the signal of motion capture module transmission, to realizeAction precisely identification, the intelligent processing system include pretreatment system, data analysis system, act preprocessed system, numberAfter the processing of analysis system, image recognition, processing procedure are completed.
The specific processing mode of the intelligent image processing system can be described as：Set by the intelligent image processing systemMotion capture scope is put, within this range, is acted after the action of implementer caught by the motion capture module, at the pre- placeJudged in reason system for action, the validity of preliminary confirmation action；Then, the time order and function order occurred according to actionAnd three-dimensional coordinate change, action sequence is established in the data analysis system, calculating analysis is carried out to sequential parameter, is completedAction precisely identification.
The intelligent display system includes display, intelligent operating system, and the intelligent image processing system is by identificationAction sequence parameter is transmitted to the intelligent operating system in the intelligent display system, is compared with systemic presupposition data, is led toCross comparison triggering respective operations to formulate, and operational order is completed into the work(such as order is performed and written contents are shown by operating systemEnergy.
The present invention can further lift sensitivity and the transmission speed of multi-touch display system, and realization acts accurateIdentification, meanwhile, the modularization of motion capture device can effectively reduce cost, the display application of flexible adaptation various sizes,Be advantageous to the optimization and upgrading of all kinds of touch display devices.

Embodiment
The present invention is best understood from for those skilled in the art, the invention will be further described with reference to the accompanying drawings and examples,Further need exist for illustrating, for the ease of description, part related to the present invention rather than full content are illustrate only in accompanying drawing.
It refer to shown in Fig. 1 to Fig. 2, the present embodiment provides a kind of multiple point touching based on graphene optical sensing technology and shownShow system, including two motion capture modules（1）, an intelligent image processing system（2）, an intelligent display system（3）.
The motion capture module (1) is embedded on the intelligent display system (3), motion capture module (1) built in lightFeel camera (1-1), and connect high dependent sensor (1-2), the high dependent sensor (1-2) is using composite graphite alkene sense film as baseSeat, to improve the sensitivity of picture catching and sensitivity.Institute is caught from different perspectives by described two light sensation cameras (1-1)Operating gesture before intelligent display system (3) is stated, the action captured is changed into signal by the high dependent sensor (1-2) transmitsTo the intelligent image processing system (2).The motion capture module (1) can freely install, dismantle, at the intelligent imageReason system (2) employing wireless is matched, and use is more convenient.
The intelligent image processing system（2）For the motion capture module（1）The signal of transmission carries out intellectual analysis,Precisely identification, the intelligent processing system are acted with realization（2）Including pretreatment system（2-1）, data analysis system（2-2）,Action is through the pretreatment system（2-1）, data analysis system（2-2）Processing after, complete image recognition, processing procedure.
The intelligent image processing system（2）Specific processing mode can be described as：Pass through the intelligent image processing systemSystem（2）Motion capture scope is set, within this range, acts the action of implementer by the motion capture module（1）After seizure,In the pretreatment system（2-1）In judged for action, the validity of preliminary confirmation action；Then, sent out according to actionRaw time order and function order and three-dimensional coordinate change, in the data analysis system（2-2）In establish action sequence, to sequenceParameter carries out calculating analysis, and execution precisely identifies.
The intelligent display system（3）Including display（3-1）, intelligent operating system（3-2）, the intelligent image processingSystem（2）The action sequence parameter of identification is transmitted to the intelligent display system（3）In intelligent operating system（3-2）, withSystemic presupposition data are compared, and are formulated by comparing triggering respective operations, and operational order is completed to order by operating systemThe functions such as order is performed and written contents are shown, realization pass through the display（3-1）Shown.
