Abstract

The invention provides a test question detection and recognition method and device, electronic equipment and a medium, which belong to the technical field of network intelligent education. The test question detection and recognition method comprises the following steps of acquiring a target image, generating a first detection result through a model detection algorithm, wherein the first detectionresult comprises a question information detection result and an answer information detection result, recognizing the first detection result by using an OCR model to obtain a first recognition result,wherein the first recognition result comprises a character line recognition result and a formula recognition result, and matching the first recognition result with preset test question template data in a database, and outputting a correction result according to the similarity. According to the method, a model detection algorithm is adopted for the target image, the question information detection result and the answer information detection result are generated, OCR model recognition is conducted on the two detection results, the character line recognition result and the formula recognition result are recognized, the detection and recognition efficiency of graphs and formulas in test questions and answers is improved, and then the correction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of network intelligent education, and in particular relates to a test question detection and recognition method, device, electronic equipment and medium. Background technique [0002] With the development of computer technology, online teaching has developed rapidly, and some corresponding teaching tool products have also emerged to provide technical support and assistance in educational guidance for students, teachers, and parents. Many teaching tool products are It can provide the function of taking photos or screenshots of questions for correction. [0003] The most important part of correcting photos or screenshots is the recognition process. The current correction tool products cannot directly handle corrections such as elementary school graphics and junior high school formula questions. Most of the graphics and formula questions are corrected through image searches. However, the method of searching fo...
