Abstract

The invention discloses a method for detecting, tracking and identifying an object abandoning / stealing event, which comprises the following steps of: 1) the detection of a moving object, namely, establishing an adaptive background model, extracting the moving object by utilizing a background difference and performing morphological processing and shadow processing to obtain a more complete and more accurate state of the moving object; 2) the tracking of the moving object, namely, realizing the inter-frame matching of the moving object through a recursion process of estimating, observing and correcting the state of the moving object, and tracking a moving track of the moving object; and 3) event identification, namely, giving a clear definition to the object abandoning / stealing event, judging the occurrence of the event according to the characteristics and the moving track of the moving object, if the event occurs, distinguishing an object abandoning event from an object stealing event, capturing evidence pictures for the identified abandoning and stealing events and giving an audible alarm.

Description

(1) Technical field

[0001] The invention belongs to the technical field of intelligent video monitoring, in particular to the detection, tracking and identification of object retention / theft events. (2) Background technology

[0002] Intelligent video monitoring system is an emerging research direction in the field of computer vision in recent years. It uses computer vision technology to analyze and understand the video data collected by cameras, and based on this to control the video monitoring system, so that the video The monitoring system has human-like intelligence, mainly involving scientific knowledge in pattern recognition, image processing, computer vision, artificial intelligence, etc. This technology includes moving target detection, moving target tracking, target classification, behavior understanding and description, etc. It is a challenging problem. In recent years, as the cost of hardware equipment (such as cameras, pan-tilts, etc.) required by the visual sur...
