Target monitoring device and method based on radar and video linkage

Abstract

The invention relates to a target monitoring device and method based on radar and video linkage. The device comprises: a radio frequency identification module which is used for identifying whether a target entering or leaving a monitoring region is an authorized target or not through a radio frequency identification tag; a radar used for recording the motion trail of an unauthorized target; a video acquisition module used for shooting a video image of the unauthorized target according to the positioning information of the radar; a front-end control module used for preliminarily judging whetherthe unauthorized target is alarmed or not according to the video image, and finally judging whether alarming is needed or not according to a rechecking result fed back by a video rechecking module; the video rechecking module used for rechecking the result whether the front-end control module needs to give an alarm or not according to the acquired image, and feeding back the result to the front-end control module; and an alarm module used for giving an alarm according to the instruction of the front-end control module. All-time all-weather active monitoring is carried out on a monitoring area, the influence of environmental factors is avoided, the accuracy is high, and the missing report rate and the false alarm rate are low.

Description

technical field [0001] The invention relates to a target monitoring device and method based on radar and video linkage, belonging to the technical field of target monitoring. Background technique [0002] With the development of society, people's travel needs are becoming more and more vigorous. Highways and railways extend in all directions, forming an intricate traffic network. The safety factors in important areas such as a large number of key road sections, level crossings, station throat areas, and passenger platforms have become increasingly prominent. The above-mentioned areas cover a large area and lack effective means to prevent the entry of surrounding people and wild animals, threatening the safety of transportation. Therefore, it is necessary to carry out all-weather, all-time, active safety protection monitoring for specific areas in the traffic road network. However, the traditional monitoring methods of artificial watch, warning, and driving away are ineffici...

AI Technical Summary

Problems solved by technology

However, the traditional monitoring methods of artificial watch, warning, and driving away are inefficient. When the monitoring area is large, or the animals entering are small, it is easy to miss, and manual monitoring is greatly affected by personnel energy, weather conditions, lighting conditions, etc. , can no longer meet the needs of the daily safety protection work of the traffic road network

[0003] In addition to the manual monitoring method, the existing technology also includes some automatic target monitoring methods, which mainly include: video analysis technology, vibration optical fiber monitoring and infrared beam monitoring, these monitoring methods generally have serious false positives and false positives, Affected by weather and environmental factors such as rain and snow, it cannot realize all-weather and all-weather monitoring, and cannot effectively distinguish legal entry and other deficiencies
