Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.In for the examples belowNumber of steps is arranged only for the purposes of illustrating explanation, does not do any restriction to the sequence between step, each in embodimentThe execution sequence of step can be adaptively adjusted according to the understanding of those skilled in the art.
As shown in Figure 1, correct method in real time the invention discloses a kind of classroom based on image recognition, this method include withLower step:
S1, acquisition student's facial image, confirmation student's number；
Specifically, it is placed in the wide-angle camera above blackboard and acquires student's face information within the scope of entire classroom, pass throughFace recognition technology matches with student's face information of system storage, confirms pupilage, and number automatically to it.
S2, the answer image for acquiring student's answer, obtain comparison result according to answer image；
Specifically, the wide-angle camera above blackboard can acquire the answer on students' selection option card in real time, pass through optical characterIdentification technology carries out the information identification of answer.
S3, association student number and comparison result, obtain answer result；
S4, answer result is shown.
Specifically, after confirming pupilage, the binding of pupilage and answer result is completed, and will identify the letter after bindingBreath is transmitted to tutoring system, by projector to blackboard, show answer as a result, selection be sent only to user and holdTutoring system mobile terminal.
It is further used as the preferred embodiment of this method, further comprising the steps of:
S5, answer is arranged as a result, obtaining score statistical information.
S6, related information and statistical information are saved to server；
Specifically, it may be configured as automatically saving statistical information, the clothes of tutoring system be automatically saved to after confirmation statistical informationBusiness device, in order to data preparation and the learning effect of inspection student's term section.
It is further used as the preferred embodiment of this method, acquisition student's facial image, confirmation student numbers this stepIt is rapid specific further include:
Student's facial image is acquired, is matched with student's face information of systemic presupposition, obtains matching result；
Specifically, wide-angle camera acquires the face information of student within the scope of entire classroom, is uploaded to tutoring system, teachingSystemic presupposition student information matches student's face information of upload with the presupposed information in system.
According to matching result, the corresponding student information of student's face information is obtained；
According to the student information of acquisition, student's number is confirmed.
Specifically, pupilage is confirmed by face recognition technology, binds the seat number of the student, class's information etc., justIn arrangement and statistical data, and confirm that student numbers, uses student's number as pupilage in subsequent statistics and displayingMark.
It is further used as the preferred embodiment of this method, the answer information of acquisition student's answer judges answer informationWhether correctly, the step for obtaining answer result is specific further include:
The answer image for acquiring student's answer confirms answer information based on optical character recognition technology, answer information is passedTransport to tutoring system；
Specifically, the examination question that projection needs student to answer is clicked in tutoring system, and option is lifted after the completion of student's answerCard shows answer, and the wide-angle camera above blackboard acquires option card information within the scope of entire classroom, known by optical characterOther technology confirms answer information, is transmitted to tutoring system.
Answer information is compared with the preset standard answer of the test item bank in tutoring system, obtains comparison result.
Specifically, examination question and model answer need to be preset in the test item bank in tutoring system, when answer information is transmitted to teachingSystem, system is interior to find preset examination question and its model answer according to examination question number, by the information and standard of the answer of transmissionAnswer is proofreaded, and record answers questions student's number of examination question, and statistics answers questions the number of the examination question.
It is further used as the preferred embodiment of this method, the answer result includes student's number and each student number pairThe comparison result answered.
Specifically, it is the comparison result after being associated with student's number that each student, which numbers corresponding comparison result,Student's number is corresponded with comparison result.
It is further used as the preferred embodiment of this method, the student information includes the face information of student, student's numberWith class's information of student, the test item bank includes examination question and item colibration answer.
Specifically, student information and test item bank are preset in system, and are stored in the storage server of tutoring system, instituteStating student information can be arranged on demand, such as number, seat number, class and contact method, the test item bank can directly from network underIt carries or the scanning of papery version examination question imports.
It is further used as the preferred embodiment of this method, the statistical information includes the accuracy of the examination question, each mistakeThe mistake of option selects rate and answers questions student's number of the examination question.
Specifically, multiple statistical data can be also arranged in the statistical information on demand, number and institute as answered questions the examination questionCorresponding student's number, fallibility item etc..
As shown in Fig. 2, system is corrected in a kind of classroom based on image recognition in real time, comprising:
Identity information module, for acquiring student's facial image, confirmation student's number；
Answering information module obtains comparison result according to answer image for acquiring the answer image of student's answer；
Relating module obtains answer result for being associated with student's number and comparison result；
Display module, for showing answer result.
Preferably, system is corrected in a kind of classroom based on image recognition in real time, further includes:
Sorting module, for arranging answer as a result, obtaining score statistical information；
Memory module, for saving score statistical information to server.
Specific embodiments of the present invention are as follows:
Using a tutoring system, student information and test question information can be preset in tutoring system, student information includes studentNumber, class number etc. can associated identity information, test question information includes examination question and item colibration answer, and the tutoring system can beIt is opened in all-in-one machine, the data of camera acquisition can also be directly transferred to tutoring system.Upper class hour religion was opened in all-in-one machineSystem, the examination question that projection needs student to practice lift tabs and show answer after the completion of student's answer.At this point, above blackboardWide-angle camera the information of student's face information and its lifted tabs is acquired within the scope of entire classroom, pass through recognition of faceTechnology and optical character recognition technology carry out information identification, complete the binding of pupilage and answer result, and identification is boundInformation afterwards is transmitted to tutoring system.Tutoring system corrects the answer of all students according to item colibration answer automatically,After the completion of correcting, answer record and statistical information are uploaded in the storage server of tutoring system automatically, so as to follow-up dataArrangement, finally by all students correct result by all-in-one machine classroom show.
