Abstract

The present invention provides an image recognition-based homework correction method, system and intelligent terminal, including acquiring image data after students answer questions, and performing image recognition according to the image data to obtain the question stem content, question type and answer content of the question to be corrected; The question type of the question to be corrected is an objective question, and the corresponding standard answer is obtained according to the content of the question. The type of the question is subjective, obtain the standard answers corresponding to all the problem-solving methods and the corresponding scoring standards according to the content of the question, compare the answer content in the answer area of ​​the question to be corrected with the standard answer, and compare the results and corresponding scores according to the comparison results. According to the sub-standard, the corresponding subjective question correction results are obtained. The invention reduces the workload of manual review and correction, improves the efficiency of homework correction, and improves the accuracy and objectivity of correction results.

Description

technical field [0001] The invention relates to the technical field of intelligent teaching, in particular to an image recognition-based homework correction method, system and intelligent terminal. Background technique [0002] With the continuous development of computer technology and educational informatization, computer technology has been gradually applied in daily education and teaching. [0003] At present, students have more and more homework, which also brings considerable workload for teachers or parents to mark homework. In addition to dealing with busy work, teachers or parents also need to mark homework. The existing homework correction method is that students submit homework, and teachers or parents collect homework and correct it and then feedback it to students, which cannot achieve the effect of timely feedback to understand the learning situation. Even if an automatic scoring system is developed in the future, most of the existing automatic scoring systems ...
