Abstract

The application discloses a video monitoring method, device and system, belonging to the field of security monitoring. The method includes: acquiring at least one target frame in a first image captured by a first camera in the binocular camera; based on the first image and a second image captured by a second camera in the binocular camera, acquiring the depth of the first image map and at least one target frame located in the depth map; determine the actual size of the target object in each target frame in the depth map based on the depth map; if the target object is determined to be an intrusion target according to the actual size of the target object, an alarm message is generated . The actual size of the target object is used to distinguish intrusion targets from small targets such as leaves or small animals, which effectively reduces the false alarm rate and improves the reliability of monitoring intrusion targets through binocular cameras.

Description

technical field [0001] The present application relates to the field of security monitoring, in particular to a video monitoring method, device and system. Background technique [0002] With the development of science and technology, perimeter security technology is widely used in airports, banks, prisons, military bases or residential areas in order to strengthen external defense and prevent the occurrence of vicious incidents. The current perimeter security technologies are various, for example, intelligent video image analysis. [0003] Usually, intelligent video image analysis can be realized through video monitoring methods. For example, cameras can be arranged in the perimeter area to monitor intrusion targets such as people or vehicles entering the perimeter area through the cameras, and send out alarm messages. [0004] When the intrusion target is far away from the camera, it is difficult for the camera to distinguish the intrusion target from small targets such as ...
