Abstract
The invention discloses an optical electronic white board system, which comprises an electronic white board, wherein the electronic white board is arranged in an outer frame; the top of the outer frame is provided with cameras; the cameras are connected with image acquisition circuits respectively; and before normal contact operation, positioning operation is firstly finished through a plurality of positioning points. According to the optical electronic white board system, quick response to a contact position on an electronic white board can be guaranteed by a PC (Personal Computer), so that the performance of the electronic white board is improved.
Description
Technical field
The present invention relates to the electronic whiteboard field, be specially a kind of optical electron whiteboard system.
Background technology
Electronic whiteboard is developed by common blank, by using electromagnetic induction principle, in conjunction with computing machine and projector, can realize with no paper office and teaching, and wherein interactive electric whiteboard can be realized the writing function of electronic whiteboard.In the prior art, when adopting operation tool to carry out operating of contacts on interactive electric whiteboard, often because the location is inaccurate, the PC that causes being connected with interactive electric whiteboard can't in time respond, and influences the normal use of interactive electric whiteboard.
Summary of the invention
The purpose of this invention is to provide a kind of optical electron whiteboard system, be prone to the inaccurate problem in location to solve prior art interactive electric whiteboard book.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of optical electron whiteboard system, it is characterized in that: include the electronic whiteboard that places housing, and the PC that is connected with the electronic whiteboard communication by the USB line, turning, outer arch both sides is respectively arranged with the camera towards the electronic whiteboard writing surface, described camera is connected with image acquisition circuit separately, and described image acquisition circuit is connected with PC by data line; PC is by USB alignment electronic whiteboard transmitting and displaying image, and on electronic whiteboard, show, when the user adopts operation tool to carry out operating of contacts on electronic whiteboard, at first position operation, the positioning action process is as follows: diverse location on the electronic whiteboard is put respectively touched to point out a plurality of anchor points, two cameras are gathered the operation tool image of a plurality of anchor point correspondences in different angles, and by image acquisition circuit with image data transmission to PC, be preset with the coordinate system of setting up according to electronic whiteboard in the PC, the position of each anchor point on electronic whiteboard that the operation tool that PC calculates according to view data is pointed out, and be mapped in the default coordinate system, obtain each positioning point coordinate, PC is according to each positioning point coordinate then, display image position to each anchor point coordinate correspondence positions, repeatedly finish positioning action behind the location, after positioning action finished, the user carried out normal operating of contacts by operation tool on electronic whiteboard.
Described a kind of optical electron whiteboard system is characterized in that: housing bottom interior wall, both sides inwall are respectively arranged with reflecting strips.
The present invention is before normal operating of contacts, utilize a plurality of anchor points to position operation, after finishing, can normally use positioning action, has high orientation precision in the time of guaranteeing normal the use, guarantee that PC can in time make timely response to contact position on the electronic whiteboard, improved the performance of electronic whiteboard.
Description of drawings
Fig. 1 is a structure front elevation of the present invention.
