Intelligent warning method based on radar and video fusion

Abstract

The invention discloses an intelligent warning method based on radar and video fusion. The steps include: 1) arranging a radar monitor and a video monitor in a designated monitoring area; 2) the radar monitor performs real-time monitoring. , output the three-dimensional position coordinates of the monitored intrusion target and issue early warning information, and at the same time control and start the video monitor to collect the current synchronous image output; 3) map the three-dimensional position coordinates monitored by the radar monitor to the corresponding 4) Identify the intrusion target in the synchronous image according to the radar detection coordinate, and judge whether it is a target that needs to be alarmed according to the image data of the identified intrusion target to determine the alarm information. The invention has the advantages of simple implementation method, intelligent identification and alarm of intrusion targets, and high alarm accuracy.

Description

technical field [0001] The invention relates to the technical field of perimeter or area protection, in particular to an intelligent warning method based on radar and video fusion. Background technique [0002] With the rapid development of society, oil, large enterprises, prisons, airports and other places have begun to be equipped with perimeter or area defense equipment to alarm when suspicious objects enter, reducing the threat of suspicious objects to surveillance sites. However, in the current perimeter or regional alert methods, usually a single monitor is used for monitoring, for example, a single radar monitor is used for early warning, or a single video monitor is used for real-time monitoring of video images. The information obtained by the method is not comprehensive and its intelligence level is low. It cannot effectively identify suspicious targets, and it is impossible to determine whether the target is the target that needs to be called. For example, the susp...

However, in the current perimeter or regional alert methods, usually a single monitor is used for monitoring, for example, a single radar monitor is used for early warning, or a single video monitor is used for real-time monitoring of video images. The information obtained by the method is not comprehensive and its intelligence level is low. It cannot effectively identify suspicious targets, and it is impossible to determine whether the target is the target that needs to be called. For example, the suspicious target is a pedestrian or other small animals (cats, dogs, birds, etc.) etc.), so it is also susceptible to false positives due to the influence of the external environment

Although practitioners have proposed a method combining video analysis and other auxiliary analysis to identify intrusion targets, for example, a Chinese patent application discloses a perimeter protection-oriented intrusion target monitoring method, through computer-aided means and video analysis technology, after target detection After the three steps of detection, target special diagnosis extraction and target classification, intelligently detect intrusion targets appearing in perimeter surveillance video, but this method needs to perform complex video analysis process, which is not conducive to fast alarm action, and it is still only Analysis that relies on video data is not conducive to the identification of intrusion targets in preparation
