Method and device for detecting rapid movement behavior of pedestrians in foggy weather

Abstract

The invention provides a detection method and a device for rapid movement behavior of a pedestrian in foggy weather. According to the detection method for the rapid movement behavior of the pedestrian in foggy weather, each original image frame in a video sequence during a preset time is processed through defogging treatment to obtain defogged images corresponding to each original image frame. The original image frames and the corresponding defogged images are respectively processed through pedestrian detection to obtain windows which have the pedestrian. As for the original image frames and the corresponding defogged images, the windows which have the pedestrian are synthesized to obtain pedestrian detection results. Movement features of the pedestrian in the video sequence are obtained according to each obtained pedestrian detection result, and whether the pedestrian has the rapid movement behavior is judged according to the movement features. By means of the technical scheme, detection accuracy of the pedestrian in foggy weather is improved, and running detection of the pedestrian is enabled to be reliable.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a method and device for detecting rapid motion behavior of pedestrians in foggy weather. Background technique [0002] Event detection means that the computer actively conducts intelligent analysis of video information, and can issue intelligent alarms for dangerous and abnormal behaviors. It plays a pivotal role in intelligent video analysis and has important application value and broad application prospects. The meaning of abnormal running is to detect whether there is a person moving fast, and to detect theft or robbery in time. Typical applications such as stations, public places, etc. [0003] However, in foggy conditions, due to the reduced visibility of the scene, the contrast and edge features of pedestrians in the image are attenuated, which affects the performance of the detection system, and may even cause the failure of the running detection algorit...
