Abstract

The invention discloses an automatic paper marking machine based on big data. The machine comprises an information receiving module, a verification module, an analysis module, a marking module and an information sending module. The information receiving module receives paper images. The verification module automatically searching verification point locations on the paper images and matching the obtained verification point locations with verification point locations formed during generation of papers at the backstage. The analysis module automatically analyzes paper point locations and intercepts test questions of papers and answers of students. The marking module matches the answers of the students with answers in a question back and carries out evaluation so as to obtain marking results. The information sending module sends the marking results to a display end or to a mobile terminal connected with the automatic paper marking machine. According to the invention, automatic marking can be performed on the paper, so the participation step of people is reduced; for the automatic marking device, one-key marking is achieved without debugging, so utilization barriers are reduced; and marking results can be fed back in real time.

Example Embodiment

[0028] Example
[0029] Reference Figure 1-2 As shown, this embodiment discloses an automatic scoring machine based on big data, which includes a housing 1, the housing 1 is provided with a touch screen 2, and the touch screen 2 is used to input operation commands and display the content of the scoring machine; 1 There is a camera 3 inside, and the camera 3 is facing the scanning area of ​​the automatic scoring machine, and the test paper information is obtained through the camera 3 above.
[0030] The housing 1 is also provided with a central processing device. The central processing device completes test paper analysis and review. For example, a flat panel can be installed in the housing 1 as the central processing device.
[0031] Such as image 3 As shown, the above central processing device includes:
[0032] Including the preprocessing module, the above preprocessing module performs filtering and binarization preprocessing on the test paper image obtained by the camera.
[0033] The information receiving module, the information receiving module receives the test paper image obtained from the camera.
[0034] The verification module, the verification module automatically searches for verification points on the test paper image received by the information receiving module, and matches the obtained verification points with the verification points formed when the background test paper is generated. Parsing module, when the verification points of the verification module match, the parsing module automatically analyzes the points of the test paper and intercepts the test questions of the test paper and student answers.
[0035] Wherein, the verification points of the verification module include: the verification points include: page number mark points, title mark points, option mark points, analysis mark points, answer mark points, and image cutting mark points.
[0036] The review module, the review module matches and evaluates the student answers intercepted by the analysis module with the answers in the question bank to obtain the review results.
[0037] An information sending module. The information sending module sends the review result of the review module to the display terminal, and the information sending module sends the review result to a mobile terminal connected to the automatic scoring machine.
[0038] The storage module, the storage module stores the review results of the automatic scoring machine, the storage module stores the question bank and the answers to the test questions, and the storage module automatically stores wrong questions and wrong question analysis.
[0039] Communication module. The communication module connects the automatic scoring machine with a number of smart mobile terminals, and the smart mobile terminal can receive the review results from the automatic scoring machine; the communication module connects the automatic scoring machine to the cloud server, and the information sending module also The review information, test paper information, and wrong question information of the automatic marking machine are sent to the cloud server.
[0040] The working principle of this embodiment is as follows:
[0041] After putting the test paper into the automatic scoring machine, take pictures and samples through the camera. The preprocessing module filters and preprocesses the test paper images obtained by the camera, and then transfers the test paper image information to the central processing device through the information receiving module. The verification module automatically finds the verification points on the test paper image received by the information receiving module, and matches the obtained verification points with the verification points formed when the background test paper is generated. Parsing module, when the verification points of the verification module match, the parsing module automatically analyzes the test paper points and intercepts the test questions and student answers in the test paper; the review module matches and evaluates the student answers intercepted by the parsing module and the answers in the question bank , Get the review results; directly feedback the review results, and can also automatically store the wrong questions, and then transmit each review information to the cloud server.
