Examination input method and system

Abstract

The invention provides an examination input method and system. The examination input method comprises the following steps: scanning an examination answer sheet or answer sheet to be input into an image; setting a region picture needing to be extracted; adopting a data extraction algorithm based on image processing to extract a region picture; carrying out judgment verification and classified storage on the information of the regional pictures, and directly storing the regional pictures which are successfully verified into a storage system; and storing the unsuccessfully verified area picture into an error processing list. According to the invention, examination papers and answer papers can be input easily and conveniently; a user can freely design test paper and answer paper, so that the operation convenience is improved, and the electronic cost of the test is saved; common examination modes and examination implementation methods are not changed, and the use burden is not increased for the user; a high-precision feature extraction algorithm based on image processing is used, so that examination data is safer and more accurate; and the image data is reserved for future reference, so that the availability and convenience of examination data filing are improved.

Description

technical field [0001] The invention relates to the technical field of examination data collection and entry, in particular to an examination entry method and system. Background technique [0002] At present, all kinds of examinations use paper-based examinations as the main method, and there are various ways to collect and enter paper-based examination answer sheets. collection. [0003] The existing commercially available cursor reader products all use relatively simple mechanical and photoelectric structures, which are highly customizable, high in price, and low in reliability. [0004] Cursor reader products need to use a special answer sheet for the exam. And in the process of use, scanning paper often has various special situations such as paper jams, double sheets, storage failures, etc. As a result, answer sheet collection is still a process that needs to be operated by professional operators. The process is complicated and the error rate is high. High data entry ...

Problems solved by technology

And in the process of use, scanning paper often has various special situations such as paper jams, double sheets, storage failures, etc. As a result, answer sheet collection is still a process that needs to be operated by professional operators. The process is complicated and the error rate is high. high data entry process

[0005] In addition, the cursor reader product cannot retain the answer sheet image, and once the collection is completed, it cannot be checked back

The reliability of the data results cannot be guaranteed

[0006] In addition, due to the defects in the mechanical structure of the cursor reader products, it is very easy to cause inconsistent results after multiple entries of the same answer sheet, and the accuracy of the data cannot be guaranteed.
