Problems solved by technology

However, the answer sheet method has a limited scope of application and is only applicable to the multiple-choice questions in the test paper, but cannot count the scores of the fill-in-the-blank questions in the test paper. It still needs to be manually reviewed by the teacher, and then the scores of the candidates are manually calculated and summarized. The teacher workload is still high

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0040] see figure 1 As shown, the embodiment of the present invention provides a statistical method for test paper scores, which is used to count the total test paper scores according to the handwritten scores of each test question, including the following steps:

[0041] S1: collect the test paper image, and preprocess the test paper image, the preprocessing is used to improve the contrast of the test paper image and remove the noise in the test paper image;

[0042] S2: Perform regional positioning on the preprocessed test paper image, and obtain the target image containing only handwritten score information;

[0043] S301: Perform fractional character segmentation on the target image to obtain character images for each test question;

[0044] S302: Preset the total number of test questions in the test paper image, calculate the total numb...

Abstract

The invention discloses a method for calculating the score of a test paper, and relates to the field of education and examination. The method comprises the steps of acquiring an image of the test paper, and performing preprocessing on the image of the test paper, wherein the preprocessing is used for improving the contrast ratio of the image of the test paper and removing noises in the image of the test paper; performing regional positioning on the preprocessed image of the test paper, and acquiring a target image only containing handwritten score information; performing score character segmentation on the target image to acquire a character image of each test question; recognizing the character image of each test question to acquire the score of each test question; and calculating and inputting the total score of the test paper. According to the method for calculating the score of a test paper, the total score of the test paper can be calculated on the basis of the handwritten score of each test question, so that the workload of teachers is reduced while artificial marking habits of the teachers are reserved, and the application range is wide.

Description

technical field [0001] The invention relates to the field of educational examinations, in particular to a method and system for counting test paper scores. Background technique [0002] In the exam marking process, the teacher manually marks the paper test papers and fills in the scores obtained for each question. After the marks are completed, the teacher manually calculates the total score of each candidate, and summarizes the scores of all candidates. The process of manually counting test paper scores requires teachers to spend more time and energy on calculating total scores and statistical summaries, which increases the workload of teachers. [0003] In the prior art, answer sheets are often used, and the answer sheet is recognized by a machine, the scores of the questions in the answer sheet are calculated, and statistics are summarized. However, the answer sheet method has a limited scope of application and is only applicable to the multiple-choice questions in the t...
