Intelligent guarding method based on radar and video integration

Abstract

The invention discloses an intelligent guarding method based on radar and video integration. The intelligent guarding method comprises the steps that 1) radar monitors and video monitors are distributed in a specified monitoring area; 2) the radar monitors performs real-time monitoring, and when entering of an invasion target is monitored, the three-dimensional position coordinates of the monitored invasion target are outputted and early warning information is emitted, and the video monitored are controlled and started to acquire current synchronous images to be outputted simultaneously; 3) the three-dimensional position coordinates monitored by the radar monitors are mapped into corresponding position coordinates in the synchronous images so that radar detection coordinates are obtained; and 4) the invasion target is identified in the synchronous images according to the radar detection coordinates, and whether the invasion target is a target required to be alarmed is judged according to the image data of the identified invasion target so as to confirm alarm information. The intelligent guarding method based on radar and video integration has advantages of being simple in realization method so that intelligent identification and alarm of the invasion target can be realized and alarm accuracy rate is high.

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
