Abstract

The invention discloses a target tracking and intrusion detection method, device and storage medium. The target tracking method includes: obtaining information of multiple targets and each target in the current image frame based on a CNN detection algorithm, obtaining a foreground image of the current image frame based on a motion detection algorithm; then obtaining confidence from the multiple targets based on the foreground image. A moving target whose degree of confidence is less than a preset first threshold; then the moving target whose confidence degree is less than a preset first threshold is matched with the moving target pool after the previous image frame update to obtain the first target. A moving target whose confidence level of the first information matching success is less than the preset first threshold; finally, the target trajectory of the current image frame is obtained based on the multi-target tracking algorithm and the second target of the current image frame, and the second target includes the first target and the target whose confidence is greater than or equal to the preset first threshold in the current image frame. Through the above method, the target detection rate is improved and the missed detection is reduced.

Description

technical field [0001] The present application relates to the technical field of security monitoring, and in particular, to a target tracking and intrusion detection method, device, and storage medium. Background technique [0002] The existing video surveillance technology is essentially human surveillance and semi-human surveillance. The semi-human surveillance method uses a simple intelligent algorithm to identify a large number of abnormal behaviors, artificially filter false alarms, and classify the alarm targets. [0003] The existing intelligent monitoring algorithms mainly include two types: one is to use machine learning methods to identify intrusion behaviors by detecting and tracking the motion trajectory of the target; trajectories to identify intrusion behaviors. However, these existing technologies still have the problems of high labor cost and many false negatives and false positives. Therefore, a new target tracking and intrusion detection method is urgently...
