Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, for those of ordinary skill in the art,
On the premise of not paying creative work, it is also possible to obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structured flowchart of imageing sensor.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
As it is shown in figure 1, this utility model include rectangular display screen body 1, be separately fixed at display screen this
Two imageing sensors 2 at two drift angles of body 1 and arrange against imageing sensor 2, light emitting region cover aobvious
The side frame of display screen body 1 and the infrared transmitting tube 3 of boundary frame area, in the side frame of display screen body 1 and boundary frame area
Side is pasted with reflective membrane 4, and reflective membrane 4 is the total reflection reflective membrane for traffic signs.Infrared transmitting tube 3 is to instead
Light film 4 launches the infrared light of specific wavelength, and imageing sensor 2 gathers the infrared light reflected by reflective membrane 4,
Reflective membrane 4 is the total reflection reflective membrane for traffic signs, the efficient reflective function of this reflective membrane, Ke Yibao
The brightness reflecting light in card imageing sensor 2 is much higher than background light, thus is effectively improved signal to noise ratio；When inciting somebody to action
When any light tight material such as finger, teacher's pointer is placed on display screen body 1, because of its block by reflective membrane 4 to
The light path of imageing sensor 2 and be imageing sensor 2 perception, now the image in display screen body 1 upper left corner passes
Sensor 2 perceives finger, teacher's pointer etc. and is positioned on line a, simultaneously the imageing sensor 2 in display screen body 1 upper right corner
Perceive finger, teacher's pointer etc. to be positioned on line b, can be counted easily by signal processing circuit of the prior art
Calculate finger, teacher's pointer etc. to be positioned on the cross point A of line a and line b；So, it is in fortune when finger, teacher's pointer etc.
During dynamic state, its dynamic position can be carried out real-time tracking by two imageing sensors 2, then by existing
Computer program receive and simulate its dynamic position signal, and show to the terminal such as projector, electronic display
Show that equipment carries control signal, the motion of finger, teacher's pointer etc. can be converted into screen in real time and show, reach
The purpose of photoelectricity interactive writing.
As in figure 2 it is shown, imageing sensor 2 of the present utility model include the image information after gathering exposure and
The image capture module of environmental light intensity, image capture module is electrically connected with parallel bus interface, and parallel bus connects
