Construction site pedestrian wandering detection method, device and equipment and storage medium

Abstract

The invention discloses a construction site pedestrian wandering detection method, device and equipment and a storage medium. The construction site pedestrian wandering detection method comprises thesteps: acquiring a frame image captured from a video stream collected by a camera installed on a construction site in real time; delimiting a pedestrian wandering detection area on the acquired frameimage; tracking each pedestrian in the detection area through deep learning in combination with a multi-target matching algorithm; calculating the track distance and the residence time of the trackedpedestrian, and identifying the pedestrian as wandering if the track distance is greater than a set distance threshold and the residence time is greater than a set time threshold; and after identifying that a person wanders, connecting an alarm to carry out early warning. According to the invention, deep learning is combined with a multi-target matching algorithm to carry out tracking calculationon each pedestrian in the detection area; therefore, whether the pedestrian wanders or not can be monitored in real time based on the behavior analysis of the pedestrian in the detection area, the precision of the detection result is improved, the tracking effect is improved, and the problem that in the prior art, a large number of missed recognition and false recognition situations occur in a method is solved.

Description

technical field [0001] The invention relates to the field of video surveillance artificial intelligence, in particular to a method, device, equipment and storage medium for detecting pedestrians wandering on a construction site. Background technique [0002] As a high-risk scene, the construction site is not only complicated, but also the management and monitoring of various pedestrians is very complicated. With the popularization of smart construction sites, the method of using video analysis and monitoring has attracted more and more attention, and the requirements for safety assurance of construction sites have continued to increase. Pedestrian wandering is a kind of abnormal behavior. On the construction site, these wandering behaviors need to be monitored. On the one hand, it is to prevent criminals from having illegal attempts. [0003] At present, most of the loitering detection methods are judged by detecting the target's motion trajectory and motion duration. But ...
