School education, as the main mode of scientific and cultural knowledge learning, is essential for helping students to master knowledge, and for courseware and examination paper practice. At present, students need to practice the courseware and examination papers no matter in primary school, junior middle school, high school and even university, and meanwhile, school teachers face correction aiming at the courseware and examination papers of dozens or even hundreds of students, and the correction workload and the working pressure of the school teachers are large.
To reduce the batching effort of teachers, automatic batching with big data is increasingly applied. However, students generally answer on paper test paper or test paper, and to implement automatic correction of paper test data, student information corresponding to the paper test paper or test paper needs to be entered, so that an automatic correction result and the student information can be automatically associated to obtain an electronic correction result of each student. Therefore, in order to enter the student information of the paper test question data before the automatic correction, the student is generally required to paste an information bar code at a specified position of the paper test question book or the test paper, and the pasted information bar code contains the information of the name, the class, the school and the like of the student, so that the automatic correction system can directly scan and read the information in the information bar code and enter the information before the automatic correction. However, on one hand, each information barcode needs to be customized and has a certain production cost, which increases the cost of the school, and on the other hand, the students may have operation problems such as mistaken information barcodes being stuck to others, wrong sticking position, information barcode being damaged and not being read, or even information barcode being lost, which results in that the automatic correction cannot be smoothly performed.
