Step S102: and acquiring reading and amending handwriting acquired by the dot matrix data acquisition equipment from the reading and amending area of the answer sheet.
In the embodiment of the application, when a teacher uses the dot matrix data acquisition device to read and edit the answer sheet, the teacher can draw and read and edit in some fixed areas of the answer sheet, and leave reading and editing handwriting in the fixed areas, where the fixed areas are reading and editing areas.
An optional working process of the dot matrix pen in the embodiment of the application during reading is as follows: when the marking is carried out, the pen point of the dot matrix pen moves on the marking area of the answer sheet, the pen point is pressed down, the pressure sensor in the dot matrix pen is triggered at the moment, then the dot matrix pen starts the high-speed camera in the dot matrix pen to carry out high-speed photographing on the dot matrix position where the pen point passes, and the paper type, the source, the page number, the position, the pen number, the handwriting coordinate, the motion track, the pen point pressure, the stroke sequence, the pen transporting time, the pen transporting speed and other information are collected and transmitted to the built-in processor, and finally the information is output to the host system responsible for data processing in the modes of Bluetooth, wi-fi or USB communication units and the like, so that both wired transmission and wireless transmission can be adopted. After the data is output to the host system, the reading and amending handwriting of the dot matrix pen in the reading and amending area can be recombined according to the coordinate information of each handwriting collected by the dot matrix pen in the reading and amending area, and the coordinates of the reading and amending handwriting on the answer sheet are obtained.
Of course, the above process of collecting and acquiring the review handwriting is only an exemplary process, and other alternative ways may be used, and the embodiment is not limited.
Step S103: and determining the test question content matched with the reading and amending handwriting on the answer sheet according to the coordinates of the reading and amending handwriting on the answer sheet.
In this embodiment, before generating the answer sheet, a corresponding test paper document needs to be generated, and the generation of the answer sheet needs to depend on the test paper document. The embodiment does not limit the generation method of the test paper document, and the test paper document can be generated by directly selecting a proper test question from the database, or a paper file is firstly digitalized and the test paper is generated according to the digitalized test question. The paper documents may include textbooks, newspapers, exercise books, examination papers, and the like. In the embodiment of the application, when the paper document is used for generating the test question document, the digitalization refers to inputting characters on a paper medium into a computer system, and then analyzing, calculating and interacting through the computer system. In addition, the test questions can be labeled, wherein labeling refers to labeling attributes of the test questions, and the attributes comprise: the question types, question stems, options, answers, analyses, knowledge points, difficulty, sources, true questions and time and the like are digitalized and labeled, and then the test questions are stored in a database. When the system generates the test question document, a database table is created, test paper numbers are generated, and test paper information (including the number of the test questions and the labeling attribute of each test question) is stored. The test paper document in the embodiment of the present application may also be a test paper set document, and the test paper set document is a collection of test paper documents.
The answer sheet in the embodiment of the application comprises answer areas, wherein the answer areas can be divided according to the specific test question conditions of the corresponding test paper, the answer areas comprise information such as the sequence, the type and the length of the test questions, for example, if the answers of the test questions are longer, the area of the divided answer areas is larger. For example, as shown in fig. 3, which is an optional style chart of the answer sheet according to the embodiment of the present application, there are multiple types of test questions, where one type of the test questions is a choice question, an answer area in the answer sheet may be a square under a corresponding option (options are [ a ], [ B ], [ C ], [ D ], etc.), and a student only needs to fill the blank square with an answer with a common pen when making the test question.
Specifically, in an optional embodiment of the present application, a dot matrix code coordinate of the reading and amending handwriting on the answer sheet is determined according to the reading and amending handwriting; and matching the dot matrix code coordinates with coordinates of the reading area in the database, and determining the test question content corresponding to the reading area according to the matching result.
The reading and amending handwriting is located in the reading and amending area corresponding to the answering area, and the answering area corresponding to the reading and amending handwriting and the corresponding test question content can be obtained according to the matching of the coordinates of the reading and amending handwriting and the reading and amending area.
Step S104: and identifying the reading and amending handwriting to determine a reading and amending result, and establishing an association relationship between the reading and amending result and the test question content.
In the embodiment of the application, the reading result obtained by identifying the reading handwriting is the reading result of the current answer sheet on the test question content, and the reading result are in one-to-one correspondence. And when the reading and amending results are determined, establishing the association relationship between each test question content and the reading and amending results thereof. Obviously, the test question content and the reading result are in one-to-one correspondence.
In this embodiment, optionally, step S104 may specifically include: and determining the reading and amending result from the database according to the dot matrix code coordinates of the reading and amending handwriting, and establishing an association relationship according to the reading and amending result and the test question content corresponding to the reading and amending result.
For example, if the test question is a first question and the reading result is an error, the established association relationship can be recorded as "the first question result is an error"; if the test question is the second question and the reading result is 10 points (i.e. the reading result can be a point), the established association relationship can be marked as "the second question result is 10 points". Of course, the association relationship may be expressed in other ways as long as the review result and the test question content can be correctly associated with each other.
Optionally, the review result in the embodiment of the application includes correct, wrong or half-half wrong, and if the review result is wrong or half-half wrong, the corresponding test question content is summarized according to the wrong or half-wrong and half-wrong review result to generate a wrong question set.
In answering, the examination question contents with the reading result of error or half-error and half-pair usually mean that knowledge points in the examination question contents are not completely understood by students.
As described above, when the reading result is a score, the reading area corresponding to each answer area on the answer sheet is added with an area in which a teacher can write the score, and the corresponding page number and coordinates are saved in the background database. When a teacher writes in the area, the dot matrix note records a writing track, scores are judged through image recognition or vector diagram recognition technology, and then the scores of the questions are obtained corresponding to the test questions.
Step S105: and generating a study situation evaluation report according to the association relation and the student identity information.
