Problems solved by technology

[0007] 1) The existing scheme needs to print specific marks on the paper, which requires the teacher to re-edit the existing questions and reprint
However, inputting and editing is a very complicated task, which is not conducive to improving the efficiency of teachers.
[0008] 2) It is not smart to take pictures to identify and divide the area. You need to click on the finger to divide the question or use the fuzzy matching method to automatically divide it. The fuzzy matching method does not have a high degree of recognition and may search for multiple questions

Embodiment 1

[0092] A system for intelligent correction of teaching and supplementary materials, including a basic data module, a shooting module, an image analysis module, a region segmentation recognition module, an OCR correction module, a display module, a deviation correction module, and a pure black background base plate;

[0093] The basic data module is used to store the basic data of teaching auxiliary materials, including the page width Wbook, page height Hbook, topic data, answer data and analysis data corresponding to each topic of teaching auxiliary materials, and the page number and the number of pages where each topic is located. The coordinate data of the question area and the coordinate data of the answer area on the page where it is located;

[0094] Wherein, when the title is a big question containing multiple small questions, the coordinate data of the topic area and the coordinate data of the answer area of ​​the topic include the coordinate data of the topic area of ​​...

Embodiment 2

[0133] This embodiment provides a method for utilizing the system described in Embodiment 1, including the following steps:

[0134] S1. After answering the questions on the supplementary materials, place the supplementary materials on the bottom plate with a pure black background, aim the camera module at the page to be corrected and shoot; when shooting, follow the photo displayed on the display module to limit the frame Guidance, limiting the content of the page to be photographed within the bounding box of the photo;

[0135] S2. The image analysis module analyzes and processes the original image captured by the shooting module, and detects the edge image of the page:

[0136] S2.1, save the original image, and copy a copy of the original image Pcopy for image processing;

[0137] S2.2. After grayscale processing is performed on Pcopy, the image is binarized using an adaptive threshold method;

[0138] S2.3. Perform three operations of dilation, erosion and dilation on t...

Abstract

The invention discloses a system and method for intelligent correction of teaching auxiliary materials. The system includes a basic data module, a shooting module, an image analysis module, an area segmentation recognition module, an OCR correction module, and a display module. The present invention proposes an intelligent correction scheme for teaching supplementary materials that have already been printed (it can be published teaching supplementary materials, or the teaching supplementary materials that teachers have already entered, edited and printed), and does not require teaching supplementary materials Therefore, there is no need to re-edit and print the teaching aids, so it has strong adaptability and will not increase the additional workload. Utilizing the present invention, after the teacher arranges the teaching auxiliary work, the students can also realize the correction in advance, so as to achieve the purpose of previewing in advance and preparing lessons in time. In addition, the present invention can realize intelligent correction of teaching auxiliary materials, which will greatly reduce the workload of teachers in checking teaching auxiliary work, and can also facilitate teachers to count the completion of teaching auxiliary work.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a system and method for intelligently correcting teaching auxiliary materials. Background technique [0002] Examinations and homework are necessary links in learning. At present, there are various marking systems and methods for examinations to improve the efficiency of marking papers, but there is a relative lack of intelligent marking methods and systems for homework after class. [0003] At present, there are many ways for teachers to assign homework, among which the more mainstream ones include the following two: [0004] 1. Existing published "workbooks", which are published books, whose content and answer areas have been fixed. [0005] 2. The teacher uses MS-Word and other software to edit the homework paper, and distributes it to the students after printing. This typesetting is edited in the manner the teacher is accustomed to. [0006] Under such assignment ...
