Description
Technical Field
The invention belongs to the technical field of image-text printing, image processing identification and automatic data acquisition, particularly provides an answer sheet adopting a composite two-dimensional code with a function of selecting answers, and particularly relates to an application mode for determining the position of a selected answer coating point and the position of a question score marking point on the answer sheet by utilizing the image identification technology of the composite two-dimensional code to realize automatic marking acquisition of answer information and score information on the answer sheet.
Background
The general questionnaires or examination paper answer sheets contain objective questions and subjective questions, and by adopting a scanning and marking method, the selected answers and score data can be rapidly collected, the marking efficiency and accuracy are improved, and big data analysis and control are implemented. The scanning and marking system for reading the examination papers commonly used at present has two categories, one is that the optical mark reader is used for scanning and acquiring data through the fixed mechanical size and the position of the selected answer coating point or the score coating point on the arranged answer sheet. The biggest defect of the system is that the position of a coating point is fixed, a user cannot adjust the position, and the application range is narrow in practical application. And secondly, in the scanner marking system, the positions of the selected answer coating points and the positions of the score marking points on different answer sheets can be adjusted by scanning parameters of marking software, so that the data acquisition requirements of different answer sheets are met. However, the software has strong parameter adjustment specialization, is complex to operate, has large workload, often needs to be operated by a specially-assigned person, and is not simple and convenient to apply. In addition, the answer sheet and the software are necessarily corresponding and belong to the same scanning and scoring software system. Or, the answer sheet in the scanning and scoring software system developed by company a cannot be guaranteed to be suitable for scanning and collecting by the scanning and scoring software system developed by company B. Such scanning and scoring software is not standardized, not universal! In other words, the answer sheet of the teaching and assistant teaching material published by a certain publishing company (in the paper marking software system of the publishing company, the position of the coating point of the selected answer and the position of the score marking point are set), and the answer sheet is not guaranteed to be suitable for every school (the purchased paper marking software of each school is different). Similarly, the scanning and marking system used by a school cannot guarantee that the auxiliary teaching material answer sheet of each publishing company is suitable. In practical application, the positions of selected answer marking points and score marking points of different examination answer sheets or questionnaires are different and different, and in order to quickly and automatically collect the selected answer information and score scores on the answer sheet, the scanning and scoring system should meet the following requirements: (1) the school user can quickly, easily and simply generate various answer sheets with selected answer coating points and score marking points, and the positions of the points do not need software positioning or mechanical positioning; (2) when scanning and marking the examination papers, the position of the selected answer coating point and the position of the score marking point on the answer sheet are automatically confirmed directly through image analysis without adjusting the positioning parameters of software, and data are collected; (3) the software for scanning and marking the paper has the universality that: the auxiliary teaching material answer sheet published by the publishing company can be suitable for a scanning and marking system of any school, and in turn, the scanning and marking system of the school can automatically scan and collect the selected answer information and score of the auxiliary teaching material answer sheet of any publishing company.
The invention patent with patent number 201310468859.0 discloses a bar code with answer-selecting function and its application, the answer-selecting bar code is used as the coating point and score mark point of the answer-selecting on the answer sheet, the setting and collection of the bar code data need not positioning, the bar code system is a standardized system, therefore, the answer-selecting bar code is used to collect the answer-selecting information and score, the scanning and marking system can be realized: the user can simply and conveniently generate the bar code answer sheet without positioning, the scanning and marking do not need to adjust the positioning parameters of the software, and the scanning software has universality. However, the one-dimensional bar code for the answer sheet is weak in error correction capability in practical application, and contains low auxiliary information capacity. Therefore, in order to better improve the performance of the scanning and marking system and enhance the reliability of the selected answer information and the score data, a two-dimensional code composite code with stronger error correction capability and larger information capacity is needed to be used for an answer sheet in the scanning and marking system, so that the selected answer and the marked score information are convenient to select, and the selected answer data and the marked score annotation information on the answer sheet are comprehensively collected by analyzing and identifying the image of the composite two-dimensional code.

The technical scheme adopted by the invention is as follows: the answer sheet comprises an answer sheet information area, a question area, a composite two-dimensional code selection answer area of an answer sheet person and a composite two-dimensional code score annotation area of a marking person.
In the selective answer area of the answer sheet person, a point-coated composite two-dimensional code is used as a selective answer coating point, and the point-coated composite two-dimensional code comprises a starting two-dimensional code, a point-coated answer selection frame, a stopping two-dimensional code and a middle interval. The start two-dimensional code and the end two-dimensional code are well-known two-dimensional barcodes such as QR code, Data Matrix, MaxiCode, Aztec, PDF417, and the like. A painted answer selection box (which may be alphabetical, or numerical, or a designated order) is arranged between the start two-dimensional code and the end two-dimensional code for selecting an answer. In the starting two-dimensional code and the ending two-dimensional code, the corresponding codes at least comprise: marking the type of the composite two-dimensional code, the serial number of the questions, the number of the selected answer point boxes, and the initial and ending mark codes. When editing answer sheets or questionnaires, the generator software generates point-coated composite two-dimensional codes, and the point-coated composite two-dimensional codes are copied and pasted near corresponding questions (each question corresponds to one composite two-dimensional code), so that the answer sheet persons can conveniently identify and answer the questions without accurate positioning. When scanning and reading the examination papers, the OCR image is analyzed, the bar code is read without software positioning, and the question serial number, the answer option and the sequence in the composite two-dimensional code are confirmed by analyzing whether the reading starting two-dimensional code and the reading ending two-dimensional code and the arranged answer selection frame are coated or not, so that the collection of the selected answer data is realized.
