Image detection method and device, electronic equipment and storage medium

Abstract

The invention provides an image detection method and device, electronic equipment and a storage medium. According to the specific implementation scheme, carrying out feature extraction on a to-be-detected image to obtain a to-be-detected feature image; processing the to-be-detected feature image by using the convolution layer to obtain the probability that the pixel points in the to-be-detected image belong to the text prediction box, the prediction positions of the text prediction box to which the pixel points belong, and the prediction positions of the question stem boxes matched with the pixel points in the answer box, wherein the text prediction box comprises a question stem box and an answer box; and according to the probability that the pixel point belongs to the text prediction box,the prediction position of the text prediction box to which the pixel point belongs, and the prediction position of the question stem box matched with the pixel point in the answer box, obtaining a matching relationship between the question stem box and the answer box of the to-be-detected image. According to the embodiment of the invention, the matching relationship between the question stem boxand the answer box can be detected from the to-be-detected image, so that the subsequent question judgment process is facilitated, and the missed judgment problem caused by the limitation of the fixed area of the answer box can be avoided.

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...

AI Technical Summary

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
