Method for implementing electronic edition standard answer, and application system thereof

Abstract

The invention discloses a method for implementing an electronic edition standard answer, and an application system thereof. The system comprises a computer and system software running on the computer. The system can comprise an image acquisition module and hardware such as a camera, a light source and a mechanical moving device or does not comprise the image acquisition module and the hardware and uses images acquired through scanning. The computer comprises complete system software and is layered; a user interface of the computer is connected with an application layer module comprising answer sheet editing, answer editing, scanning and marking, result displaying and managing, assisting and system managing; and a system control layer below an application comprises a data communication module, an image processing module, a mode matching module of the image processing module, a data management module and a database. Due to the electronic edition standard answer and a given image processing mode matching algorithm, an editable answer sheet system can improve the marking efficiency, namely increase the marking speed by limiting a comparison region, and support complicated application such as various answer sheet types, multiple pages and large-scale examination marking.

Description

Technical field: [0001] The invention relates to a digital image processing technology for machine marking, in particular to a method for realizing electronic standard answers and an editable answer card system using the method. Background technique: [0002] The use of answer sheets in many school exams or professional exams can save teachers time and improve the accuracy of judging questions. [0003] Answer card systems / apparatus / equipment currently on the market, i.e. traditional answer card systems, are all a class of specialized electronic instruments, either desktop or hand-held. Answer sheets are suitable for multiple-choice questions, including single-choice questions, multiple-choice questions, and true / false questions, usually marked with English letters (A), (B), (C), (D), .... When choosing an answer, candidates need to blacken the corresponding letter with a pencil. Use in two steps. First of all, the user (that is, the user, the questioner rather than the e...

AI Technical Summary

Problems solved by technology

[0005] 1) The system is bound to a special device / instrument, so powerful software and hardware tools such as graphics software tools, data and file management tools, powerful and flexible computer languages, etc. on ordinary computers cannot be used

It is also not conducive to popularization

[0006] 2) Depending on the specific body shape design, users cannot create and edit the card face design, which is inconvenient and not conducive to anti-cheating

[0007] 3) Depends on specific paper, not ordinary printing / copying paper

Therefore, not only the cost of use is higher, but also extremely inconvenient for many users.

[0008] 4) It is not possible to judge papers remotely, which is very inconvenient today when computer and network technologies are very developed and popular

[0009] 5) The management of its results is not as flexible, easy to use, reliable and convenient as on ordinary computers

[0010] 6) The standard answer needs to be formulated in advance on an answer sheet, which is scanned and entered, and cannot be edited and modified at will, which is inconvenient to use

The process of creating and editing answer sheets in this way is cumbersome, slow, and prone to errors

[0013] 2) The creation of standard answers is entirely limited to the way the user selects the answer with the mouse on the software graphical user interface. Although the process is very intuitive, it is not only very slow, but the process is cumbersome, prone to errors, and unfavorable to management

It is also not conducive to manual re-inspection when necessary

[0014] 3) The creation of standard answers is completely limited to the user on the software graphical user interface, so that the software can only be saved in the form of graphics or images, which takes up a lot of computer storage resources and is not conducive to management

Nor can it support remote marking and distribution of marking in large-scale examinations

[0015] 4) The standard answer sheet obtained by traditional scanning and the electronic version of the standard answer sheet described in the reference patent require a full-image comparison between the multi-standard answer image and each test paper image, which takes up a lot of computer CPU time and slow calculation speed
