Abnormal behavior detection method and device, electronic equipment and storage medium

Abstract

The invention provides an abnormal behavior detection method and device, electronic equipment and a storage medium, and the method comprises the steps: inputting an abnormal behavior video image into a trained abnormal behavior detection model, and obtaining an abnormal behavior detection result; wherein the trained abnormal behavior detection model is obtained by inputting an abnormal behavior video sample image into a preset fusion network for training; wherein the abnormal behavior video sample image carries an abnormal behavior region information weak label; wherein the preset fusion network is obtained by fusing a classification model and a target detection model. According to the trained abnormal behavior detection model, the classification model and the detection model are fused to form a deep learning framework, and the detection model is used as a weak supervision model to assist in completing the task of image classification, so that excessive manual annotation is omitted, the classification model does not lose key information of a shallow network, and the detection efficiency is improved. Therefore, the classification accuracy of the model is improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, and in particular, to a method, device, electronic device and storage medium for detecting abnormal behavior. Background technique [0002] With the progress of society and the development of science and technology, video surveillance has penetrated into various fields such as transportation, community, and industry, and algorithms for monitoring abnormal video behaviors based on deep learning have also been applied and developed. [0003] Deep learning learning based on a large number of samples is robust to different environments. Abnormal behaviors are different from normal behaviors, which refer to behaviors that are unfavorable to social security and the current environment or rarely occur, such as fighting, smoking, and falling. Due to the characteristics of abnormal behavior itself, the data of abnormal behavior is small and difficult to collect, which is not conduc...
