Radar and video fused large-scale monitoring system and method

Abstract

The invention discloses a radar and video fused large-scale monitoring system and method. The device comprises a central control device and monitoring terminals which are connected with the central control device and respectively arranged at needed monitoring areas; the monitoring terminals comprise a controller, a video monitoring module and a radar monitoring module composed of more than one radar monitor, wherein the video monitoring module and the radar monitoring module are respectively connected with the controller; all radar monitors are arranged at the needed directions where the needed monitoring areas can be completely covered within each corresponding coverage area; when a target radar monitor monitors a target, the controller controls the video monitoring module to adjust an acquisition direction and transmit an acquired target image to the central control device to perform recognition and tracking. The method uses the system to realize large-scale intelligent monitoring. The radar and video fused large-scale monitoring system and method provided by the invention have the advantages that omnidirectional intelligent monitoring of a large-scale area can be realized, the target can be quickly and accurately tracked and recognized and the monitoring precision is high.

Description

technical field [0001] The invention relates to the technical field of large-scale area monitoring, in particular to a large-scale intelligent monitoring system and method for radar and video fusion. Background technique [0002] In some applications that need to monitor fixed areas, such as the monitoring of public areas such as airports and the security of specific areas such as field camps, it is necessary to install monitoring devices to monitor the area; in practical applications, it is usually required to be able to monitor Surrounding 0~360 degrees, all areas within the detection range of the monitoring device can be monitored. The current monitoring system mainly includes two types of perimeter monitoring system and area monitoring system. The perimeter monitoring system generally uses microwave radar anti-radiation protection, video surveillance protection, infrared anti-radiation protection, cable protection, etc. to perform monitoring. It is aimed at a line There...

Problems solved by technology

The current monitoring system mainly includes two types of perimeter monitoring system and area monitoring system. The perimeter monitoring system generally uses microwave radar anti-radiation protection, video surveillance protection, infrared anti-radiation protection, cable protection, etc. to perform monitoring. It is aimed at a line Therefore, it can only be applied to the monitoring and protection of linear areas, and cannot monitor the areas that require multi-directional protection; the area monitoring system usually installs the radar on a rotatable base, and through the rotation of the radar to achieve each Angle (360-degree) monitoring can realize the monitoring of multiple directions in the monitoring area

However, the above-mentioned method of using rotating radar for area monitoring, on the one hand, there will be a certain time interval between two scans in the same direction, that is, the tracking of the target is not continuous, and it is easy to miss the target, and due to the small amount of data, It is not easy to do filtering processing, and it is also susceptible to interference from the external environment, so the monitoring accuracy is low; on the other hand, the radar can only detect the moving target, and cannot distinguish the type of the target at the same time, and due to the limitation of the structure of the rotating radar base , and it is not convenient to install an image acquisition device such as a camera to further judge the type through manual or program detection
