Problems solved by technology

[0002] The current video surveillance in the airport security check area has the characteristics of numerous monitoring points, large monitoring range and complex monitoring content.
The efficiency of detecting airport security problems is getting lower and lower by relying only on the traditional "human eye" monitoring mode of watching many videos, and it is difficult for security personnel to monitor and discover sudden or threatening security incidents in real time and effectively
Secondly, after a security incident occurs, it is difficult to quickly and accurately search for on-site relevant information in massively stored videos

Abstract

The invention discloses a method for identifying behaviors in a security check channel based on image processing. The method comprises the following steps: acquiring an original image acquired by a camera in a security check area; separating a moving target and an image background in the original image; performing target tracking on the moving target in each frame of the original image; and extracting target features of the moving target, then judging whether the moving target is an abnormal behavior according to the target features of the moving target, and generating an alarm. According to the method, the target in the dynamic scene can be effectively positioned, identified and tracked, and whether the behavior of the target is consistent with the known abnormal behavior is analyzed and judged, so that field information recording and security early warning can be carried out in time when the abnormality occurs.

Description

technical field [0001] The invention relates to the field of monitoring systems, in particular to an image processing-based behavior recognition method in a security inspection channel. Background technique [0002] The current video surveillance in the airport security check area has the characteristics of numerous monitoring points, large monitoring range and complex monitoring content. The efficiency of detecting security problems at airports is getting lower and lower by only relying on the traditional "human eye" monitoring mode to watch many videos, and it is difficult for security personnel to monitor and discover sudden or threatening security incidents in real time and effectively. Secondly, after a security incident occurs, it is difficult to quickly and accurately search for on-site relevant information in massively stored videos. Contents of the invention [0003] The invention provides an image processing-based behavior recognition method in a security inspec...
