Description
Technical field
The present invention relates to wisdom teaching field, especially a kind of touch of wisdom blackboard is given lessons technology.
Background technique
Touch screen technology is as a kind of interaction type input apparatus, because it is relative to mouse and keyboard, has easy to operate, makes
With it is flexible the features such as, help to improve the use enthusiasm of user, be widely used.But current mode of giving lessons is big
Part still rests on traditional teaching pattern, or by way of lantern slide, blackboard cannot lead at most to show
It crosses the mode touched and realizes teaching of giving lessons.
Summary of the invention
It is an object of the invention to overcome the technical problem present on, the touch for providing a kind of wisdom blackboard is given lessons skill
Art.
To achieve the above object, the technical scheme is that in the following manner realizing:
A kind of touch of wisdom blackboard is given lessons technology, including wisdom blackboard body, is equipped in the wisdom blackboard body
Lecture system, the lecture system include video acquisition module, image processing module, touch point identification and locating module and mouse
Analog module.
Further, the video acquisition module is passed by the video signal that USB interface acquires two cameras
It is defeated by described image processing module.
Further, described image processing module is to pre-process received image data, and treated by general
Image data is sent to the touch point identification and locating module.
Further, the touch point identification and locating module are counted according to the image data of described image processing module
Number and the position of touch point are calculated, and carries out two dimensional coordinate map, is corresponded in the coordinate of display screen, and send the data to
Mouse emulation module.
Further, the mouse emulation module to according to touch point identification and the motion profile of locating module into
Row judgement, and then simulate mouse action.
The beneficial effects of the present invention are: acquiring video signal by video acquisition module and being transferred to image procossing mould
Block, image processing module are transferred to touch point identification and locating module, touch point identification and positioning after pre-processing to image
Module can calculate the dynamic position of display screen like clockwork, and be operated by mouse emulation module simulation, to realize
It carries out touching on wisdom blackboard and give lessons, solve the problems, such as that conventional teaching is given lessons technology, and the competitive advantage of product is improved.
Detailed description of the invention
Fig. 1: a kind of touch of wisdom blackboard of the present invention is given lessons the system architecture diagram of technology.
Fig. 2: a kind of touch of wisdom blackboard of the present invention is given lessons the operation schematic diagram of technology.
Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
Technology, including wisdom blackboard body as shown in Figure 1, a kind of touch of wisdom blackboard is given lessons, the wisdom blackboard sheet
Lecture system is installed in vivo, the lecture system includes video acquisition module, image processing module, touch point identification and positioning
Module and mouse emulation module.The video acquisition module passes through the video signal that USB interface acquires two cameras
It is transferred to described image processing module.Described image processing module will be located to pre-process received image data
Image data after reason is sent to the touch point identification and locating module.Wherein pretreatment mainly includes carrying out image grayscale
Change, the system resource that the amount of storage and processing image for reducing image file need to spend；While in order to eliminate the noise in image
And interference, strengthen useful information, using median filtering and grayscale equalization technology；Segmented image obtains the portion that system is mainly studied
Point, i.e., as the straight line for having one fixed width of virtual display curtain.Image after pretreatment conveniently accurately carries out movement touching
Touch detection and identification a little.The touch point identification and locating module are counted according to the image data of described image processing module
Number and the position of touch point are calculated, and carries out two dimensional coordinate map, is corresponded in the coordinate of display screen, and send the data to
Mouse emulation module.The mouse emulation module according to touch point identification and the motion profile of locating module to be sentenced
It is disconnected, and then simulate mouse action.
The present invention acquires video signal by video acquisition module and is transferred to image processing module, image procossing mould
Block is transferred to touch point identification and locating module after pre-processing to image, touch point identification can accurate nothing with locating module
The dynamic position of display screen accidentally is calculated, and is operated by mouse emulation module simulation, is carried out on wisdom blackboard to realize
Touch is given lessons.
The lower course of work of the invention is briefly described below:
As shown in Fig. 2, calling camera video acquisition after system program initialization first, video image data is acquired, and
Video image data is sent to image processing module and carries out image preprocessing, image touch points knowledge is entered after image preprocessing
Not, image touch points recognition detection is a little or multiple spot is then needed to a motion state analysis, after analysis if it is multiple spot
It carries out multiple point touching movement to determine, then determines that touching point location then can directly determine touch point location if it is a bit,
The conversion of touch point coordinate then may be implemented after touching point location, to finally complete human-computer interaction, i.e. the skill of giving lessons of wisdom blackboard
Art.
Finally, it should be noted that above embodiments are only to illustrate the present invention and not limit technology described in the invention
Scheme；Therefore, although this specification is referring to above-mentioned each embodiment, the present invention has been described in detail, this
Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of invention, should all cover within the scope of the claims of the present invention.
