Description
[technical field]
The utility model relates to a kind of image interactive product, particularly a kind of image electric whiteboard device of supporting writing pencil and reflective pen.
[background technology]
Image interactive product or only support photoelectric pen to write interactive operation writing on zone or display panel in the market, or only support directly to touch interactive operation with finger writing on regional and display panel.
Use the image interactive product of photoelectric pen can realize writing accurately and interactive operation, its photoelectric pen is write principle: in written position, one infrared emission fluorescent tube is installed, put the cap for brush that the leaded light high-abrasive material is done, place circuit and the battery of controlling the infrared emission fluorescent tube in a body, nib touching display surface when writing, trigger lamp tube control circuit emission infrared ray, infrared ray is through the optical material of nib, can launch uniformly Infrared, what see at infrared camera is exactly a circular light spot, determines writing position according to hot spot.This photoelectric pen must be supporting with this image interactive product, also need regularly with changing battery or the charging guarantee normally uses, in case photoelectric pen does not have electricity, the image interactive product just cannot use, and the voltage of battery can reduce along with user's use simultaneously, can affect like this pressure sensitivity characteristic and the bearing accuracy of pen, feel not to be consistent all the time with pen, along with the variation of battery electric quantity, the sensation of style of writing is also along with variation, and is handy not for the user.
And directly use finger to touch interactive operation, very convenient, need not specific photoelectric pen, also need not with changing the operations such as battery or charging, but large scale write zone or viewing area write etc. long-time long Writing distance touch towards the time, finger has pain unavoidably, simultaneously finger or other material objects when carrying out touch operation due to angle, contact area, writing the reason such as thing out-of-shape can shine into and write precision and reduce, operate the problems such as insensitive, cause user's experience good opinion to reduce.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of image electric whiteboard device of supporting writing pencil and reflective pen, and it not only can solve the discomfort of finger touch, can also solve and be subjected to the battery limitation problem when touching with style of writing.
The utility model is achieved in that
A kind of image electric whiteboard device of supporting writing pencil and reflective pen comprises an electronic whiteboard, is used for a writing pencil and the reflective pen write on electronic whiteboard.The lower frame of described electronic whiteboard, left frame and left frame all arrange the infrared reflecting band, the upper left corner of described electronic whiteboard and the upper right corner respectively arrange a camera module with camera and infrared transmitting tube, the camera of two described camera modules is mutually an angle of 90 degrees, two camera modules all are connected to a CPLD processor, described CPLD processor connects a SRAM storer, and the CPLD processor is connected to computing machine by an arm processor, the nib of described reflective pen arranges a reflecting strips, and described reflecting strips is around nib one circle
Further, the width of described reflecting strips is at 10 to 15 millimeters.
Further, described reflecting strips is the reflecting strips of reflected infrared.
Further, described writing pencil is the pen of reflected infrared not.
The utility model has the advantage of:
The utility model both can be realized finger touch, supported again writing of lettering pen and two kinds of pens of reflective pen, and two camera module acquisition of image data go out writing position according to the shade in image or speck position calculation, write precision high.Two kinds of pens of this practical support do not need the support of power supply, and are therefore simple, and use convenient.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model electronic whiteboard.
Fig. 2 is the structural representation of the reflective pen of the utility model.
Fig. 3 is the utility model circuit theory diagrams.
Fig. 4 is the shade schematic diagram of the utility model touch location when adopting finger touch or writing pencil to write.
Fig. 5 is the hot spot schematic diagram of the utility model touch location when adopting reflective pen to write.
[embodiment]
See also Fig. 1 to Fig. 2, a kind of image electric whiteboard device of supporting writing pencil and reflective pen, the writing pencil (not shown) and the reflective pen 2 that comprise an electronic whiteboard 1 and be used for writing on electronic whiteboard 1.The lower frame of described electronic whiteboard 1, left frame and left frame all arrange infrared reflecting band 3, and the upper left corner of described electronic whiteboard 1 and the upper right corner respectively arrange a camera with the described camera module 4 of camera module 4, two of camera and infrared transmitting tube and be mutually an angle of 90 degrees.Please consult Fig. 3, two camera modules all are connected to a CPLD processor again, and described CPLD processor connects a SRAM storer, and the CPLD processor is connected to computing machine by an arm processor.Described writing pencil is the pen of reflected infrared not.The nib of described reflective pen 2 arranges a reflecting strips 21, and described reflecting strips 21 is around nib one circle.Described reflecting strips 21 is the reflecting strips of reflected infrared, and the width of described reflecting strips 21 is at 10 to 15 millimeters.If the too wide waste material of width, width is too narrow, and reflection strength is inadequate, can cause misjudgment.In principle, on its width and image electric whiteboard device, the width of reflective tape 3 is consistent better.
Principle of work of the present utility model is: the infrared transmitting tube of the camera module 4 in electronic whiteboard 1 upper left corner illuminates the infrared reflecting band 3 on electronic whiteboard 1 lower frame and left frame, the infrared transmitting tube of the camera module 4 in electronic whiteboard 1 upper right corner illuminates the infrared reflecting band 3 on electronic whiteboard 1 lower frame and left frame, and the picture that such two camera modules 4 photograph is exactly a light belt.See also Fig. 4, when using finger to block or writing pencil when touching, the position, touch point is dimmed; See also Fig. 5, when using reflective pen 2 to write, by the reflex of 21 pairs of light of reflecting strips, the picture that camera module photographs can brighten at writing position.The view data that described left and right two camera modules 4 gather is distinguished to be stored in described SRAM storer by address wire.Described CPLD processor sends to two infrared transmitting tubes and sends pwm signal, drive two infrared transmitting tubes and launch infrared ray, described arm processor is configured two camera modules, and the view data that collects is carried out analyzing and processing, and view data is passed to computing machine by USB interface.View data is calculated in computing machine, draws shade or speck position, thereby determines to touch or writing position, and registration.
The utility model both can be realized finger touch, can realize again writing of lettering pen and two kinds of pens of reflective pen, and two kinds of pens did not need the support of power supply.Therefore, the utility model is simple, and uses convenient.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
