Image detection method, device, electronic device and storage medium

Abstract

The application proposes an image detection method, device, electronic equipment and storage medium. The specific implementation plan is: extract the features of the image to be detected to obtain the feature image to be detected; use the convolution layer to process the feature image to be detected to obtain the probability that the pixel in the image to be detected belongs to the text prediction box, and the text to which the pixel belongs The predicted position of the prediction box, and the predicted position of the stem box matching the pixel in the answer box; the text prediction box includes the question stem box and the answer box; according to the probability of the pixel belonging to the text prediction box and the text prediction to which the pixel belongs The predicted position of the box, and the predicted position of the stem box matching the pixels in the answer box, obtain the matching relationship between the question stem box and the answer box of the image to be detected. The embodiment of the present application can detect the matching relationship between the question frame and the answer box from the image to be detected, so as to facilitate the subsequent question judgment process, and can avoid the missed judgment problem caused by the fixed area limitation of the answer box.

Description

technical field [0001] The present application relates to the field of information technology, and in particular to an image detection method, device, electronic equipment and storage medium. Background technique [0002] At present, in the education and teaching scene, most of the students' homework or test papers are still manually reviewed, and the workload of reviewing students' homework or test papers is relatively large, which brings a huge workload to parents and teachers. In response to this phenomenon and problem, with the continuous development of computing technology and artificial intelligence technology, artificial intelligence technology has been gradually applied in education and teaching scenarios. In some large-scale educational scenarios, various methods and systems for automatic question judgment and automatic marking have been promoted. [0003] In the relevant photographic judgment or automatic judgment system, most of the answer sheets scribbled by stu...

Problems solved by technology

This method virtually increases the cost of answering time for students to answer questions, and is even prone to filling errors and omissions

In addition, some subjective questions require students to write the answers in the fixed area of ​​the answer box. When the handwritten answer exceeds the answer area, the problem of missed judgment will occur
