Description
Technical field
The present invention relates to wisdom teaching field, especially a kind of lecture system of wisdom blackboard.
Background technique
Teaching majority based on Traditional Classroom is to surround the facilities such as dais and blackboard, for the purpose of facilitating teachers' instruction,
Have ignored the impression of students, student according to teacher mode of giving lessons it is stiff learn, the chance independently experienced is seldom.Always
Teacher lectures as leading mode, and this teaching method will lead to the exhaustibility of student after last longer.For one
The classmate for liking mischievous a bit begins to take advantage of teacher to turn one's head and whisper to each other when writing, and does various little tricks；For listening to the teacher
Good student for, they have also formed the habit for accepting teacher on classroom, and teacher occupies absolutely leading position, only when
When teacher puts question to, they are possible to show their subjective initiative, cannot convey him to teacher in time in this way
State of listening to the teacher, to the understanding situation of some knowledge difficult point during also listening to the teacher.Teacher can not carry out coequally with student
The happy exchange of position is always given lessons with a kind of posture higher than student, thus enthusiasm and interest that them can not be excited to learn
Taste.
Summary of the invention
It is an object of the invention to overcome the technical problem present on, a kind of lecture system of wisdom blackboard is provided.
To achieve the above object, the technical scheme is that in the following manner realizing:
A kind of lecture system of wisdom blackboard, including wisdom blackboard body, the wisdom blackboard body includes control unit,
And the display module and image processing module being connect with control unit；Kinect detector, the Kinect detector and institute
State control unit electric connection；Kinect management software is wrapped for receiving the data of described image processing module and being handled
Include gesture recognition module, action recognition module and speech recognition module.
Further, the Kinect detector is made of an infrared projection machine, colour imagery shot and infrared camera,
The color image size of generation is 640*480,30 frames of capture per second.
Further, the display module is liquid crystal touch display screen.
It further, further include projector, the projector and described control unit are electrically connected.
It further, further include voice playing module, the voice playing module and described control unit are electrically connected.
The beneficial effects of the present invention are: using Kinect somatosensory technology can scene in high fidelity learning by imitation,
The process of giving lessons can be made more interesting, thus make student classroom performance more vividly live wave.It is introduced in teaching process
The application of body-sensing technology makes student passively receive knowledge and is changed into oneself Active Learning and understands knowledge, promotes student's study
Enthusiasm, persistently enhance and promote the consciousness of their Active Learnings.
Detailed description of the invention
Fig. 1: a kind of hardware configuration of the lecture system of wisdom blackboard of the present invention forms figure.
Fig. 2: a kind of software configuration of the lecture system of wisdom blackboard of the present invention forms figure.
A kind of Fig. 3: work flow diagram figure of the lecture system of wisdom blackboard of the present invention.
Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
As shown in Figs. 1-2, a kind of lecture system of wisdom blackboard, including wisdom blackboard body, the wisdom blackboard body
Including control unit, and the liquid crystal touch display screen and image processing module that are connect with control unit；Kinect detector, institute
It states Kinect detector and described control unit is electrically connected；Kinect management software, for receiving described image processing module
Data and handled, including gesture recognition module, action recognition module and speech recognition module.
Wherein, the Kinect detector is made of an infrared projection machine, colour imagery shot and infrared camera, is generated
Color image size be 640*480,30 frames of capture per second.
For the ease of further understanding the present invention, the working principle of lower Kinect is briefly described below:
Kinect somatosensory detector brings completely new experience and interaction design to user, started one kind allow user more
Comfortably, acceptable interactive mode.Compared with traditional camera, Kinect camera is available to image to object distance
The distance of head, this is that common camera is not accomplished, the depth information that it obtains object mainly passes through infrared light reflection hot spot
Diffraction information obtains.If Kinect somatosensory detector will obtain depth information it may first have to get the 3D depth of human body
Information, then by handling the data of acquisition after, to calculate the position of skeleton node, including 20 ratios
The key bone node such as more crucial bone nodal information, such as head, neck, backbone, leg.Then the scanning letter of infrared ray is calculated
Breath, so that it is determined that the specific location of the profile of user and their limbs.To judge the posture of user, it is corresponding to capture user
Movement.Kinect can acquire audio-frequency information, can filter out background noise, accurately identify the voice of user, in this way
It can support voice control.This technology better uses Kinect in classroom teaching.
Preferably scheme further includes projector, and the projector and described control unit are electrically connected.
Preferably scheme further includes voice playing module, and the voice playing module and described control unit are electrical
Connection.
Workflow of the invention is described further below:
As shown in figure 3, detailed step of the invention is: (1) selecting a Kinect connecting with wisdom blackboard body to set
It is standby, start and it is initialized；(2) image processing module is called, color flow image, skeleton data stream are opened, creates audio-source
Object acquires audio signal；(3) it after being analyzed using acquired image data, depth data, voice data, is utilized respectively
Corresponding module carries out action recognition, gesture identification and speech recognition in Kinect management software；(4) pass through the result of identification
It is matched with predefined movement, gesture, voice, if successful match, executes corresponding operation；(5) data flow is closed, is moved back
Out.
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.
