Description
Technical field
The present invention relates to Computerized Information Processing Tech, and in particular to a kind of student classroom prison based on handset image collection
Examining system and its monitoring method.
Background technology
Student's plenty of time has been corroded in current online game such as opium, it is easy to student is can not extricate oneself, causes classroom
Time is also often occupied.Document records student's averagely daily surf time in 2-6 hours, has a strong impact on student's school work and body and mind
Health.Change this situation in addition to improving teaching method, simple in real time, accurate, reliable monitoring management and control is imperative.Pass through
Sensor realizes that automatic monitoring management and control is of great importance for improving Classroom Teaching.But automatic monitoring because student's quantity is more,
Information stability is poor, identity validation difficulty, student classroom context identification difficulty etc. problem be present.
The content of the invention
Goal of the invention：It is an object of the invention to solve the deficiencies in the prior art, there is provided one kind is based on mobile phone figure
As the student classroom monitoring system and its monitoring method of collection, the present invention can greatly save the hardware cost of IMAQ, lead to
Cross mobile phone app and improve the accuracy rate that pupilage confirms and judged student classroom state.
Technical scheme：A kind of student classroom monitoring system based on handset image collection of the present invention, including system service
Device and student client；First data transmission module, authentication module and IMAQ are provided with the student client
Module, student verify identity information by authentication module, and image capture module gathers the facial image information of student, passed through
First data transmission module transmits the identity information of student and facial image information into system server；The system service
Include face-image analysis module, the second data transmission module and statistical analysis module, face-image analysis module root in device
The facial image information received according to the second data transmission module judges the state of listening to the teacher of student, statistical analysis module statistic
Time of listening to the teacher accounts for whole time in classroom ratio deposit database file and forms report file.
Wherein, authentication module can use the technology of registering of existing radio-frequency card (mess card) checking.
For ease of " gathering materials on the spot ", convenient, flexible quick realize monitors purpose, and the system server is the meter in classroom
Calculation machine, the student client are the mobile phone with camera function of student.
Further, the first data transmission module and the second data transmission module complete image using bluetooth module
The transmission and receiving of data, and then realize and transmit the image information data of student client collection to system server.
Further, inputted by the identity validation module directly in student client student number carry out identity registration and
Confirm, and contrasted by image information and carry out identity validation, improve the accuracy of identity validation and be easy to statistical summaries.
Further, face in the two width face-images that the face-image analysis module is continuously scanned according to student client
The size of the area (height) in portion judges that student is to listen to the teacher or " bowing ", specific method are：When mobile phone is horizontal positioned, bow
When seeing the mobile phone, face area (height) is larger, and face area (height) is smaller when listening to the teacher, and by setting a monitoring numerical value, surpasses
It is currently to be in " bowing " state that the student is then thought when crossing the face area monitoring numerical value.
It is relevant with the angle of face when listening to the teacher when above-mentioned monitoring numerical value is placed with mobile phone.Numerical value number can be according to a large amount of systems
Count determination.It is probably to record the note because student bows, then needs (such as one minute) collection at regular intervals to send image
Once, because judging easily there is larger error when times of collection is less, but the statistical result of mass data is comparatively accurate, example
A such as class 45 minutes, one minute run-down, it is more accurate to analyze state of listening to the teacher according to 45 scanning results.
Further, setting gathers the time interval of image in image capture module, and such as 5 minutes once, according to continuous two
" bowing " between secondary whether state analysis statistic time of listening to the teacher accounts for whole time in classroom ratio, by adopting at time intervals
Collect student's image facial information and greatly reduce the amount of calculation of server.
The invention also discloses a kind of monitoring method of the student classroom monitoring system based on handset image collection, wrap successively
Include following steps：
(1) student logs in monitoring system APP by student client with student number, and system server is stepped on by inputting class number
Record monitoring system, student client and system server and communication connection is established by bluetooth；
(2) sampling time is set in system server, student client receives the sampling time of host setting；
(3) after student client reaches the sampling time of setting, the facial information of student is gathered, and be sent to system service
Device；
(4) after system server receives the facial information of student, image border is extracted, face area is selected and then determines to learn
Raw state of listening to the teacher；
(5) listen to the teacher state at different moments of the system server according to student within a period of time, carrys out statistical analysis student
Listen to the teacher the time；
(6) after End-of-Course, above-mentioned time data of listening to the teacher is stored in database file and forms report file.
Beneficial effect：The present invention by verifying the identity of each student, and by facial information (whether is " bowing ") come
The state of listening to the teacher of student is monitored, analytic statistics student accounts for whole time in classroom ratio at time of listening to the teacher.In a word, the present invention can be very big
The hardware cost of the saving IMAQ of degree, pupilage is improved by mobile phone app and confirms and judge student classroom state
Accuracy rate.
Brief description of the drawings
Fig. 1 is the program flow diagram of the present invention.
