System background
In forest fire prevention, frontier defense, coastal defense, port, oil field and other wide-area video surveillance fields, the application of long-distance and ultra-long-distance video surveillance products is becoming more and more extensive. It can not only realize the monitoring distance of 15Km, but also integrate visible light and thermal imaging observation cameras with the function of fog penetration. At night, it can also use auxiliary light source or thermal imaging for target detection. Image information has both spatial resolution and time resolution. Not only the information of the detection object, but also the information of the scene space environment; It contains both static information and dynamic information of the observed target. The software system is also more intuitive, helping to judge. But many products in the actual use of the process also found some problems. For example, limited viewing range in severe weather due to optical visibility; The accurate location, geographic information, speed and other information of the moving target cannot be detected.
Compared with optical detection, radar can carry out a large range of search without being affected by optical visibility, and obtain moving target information with high accuracy. Taking ordinary civilian fishing boat radar as an example, it can identify more than 500 targets within 6 nautical miles around. Calibration target location information (latitude and longitude), navigation information (heading speed), radar information (echo area) and other data, but the radar acquired target information is relatively abstract, if these two systems can be integrated will be helpful to the development of wide-area video surveillance field. This paper will focus on the introduction of radar security system for wide area video surveillance applications into new blood.
Radar security solution is a comprehensive security solution of radar and camera linkage. Compared with the method of only using cameras, the radar can maintain normal operation without being affected in weather conditions such as daytime, night, haze, dust, rain and snow. This solution using radar and camera linkage is widely promoted and applied in the world.
Scheme introduction
Radar security solution is a comprehensive security solution of radar and photoelectric system. It integrates radar with CCTV video monitoring, infrared monitoring and other means to realize the function of radar automatically discovering and identifying suspicious intrusion targets, and automatically mobilizing camera tracking and monitoring suspicious targets, thus greatly improving the work efficiency of monitoring personnel. Compared with the method of only using cameras, the radar system can maintain normal operation without being affected no matter in the weather conditions of day, night, haze, dust, rain and snow. The system makes full use of the advantages of a wide range of radar detection, a large perception area and a full range of targets. It uses remote photoelectric equipment to conduct all-weather imaging screening of key targets, and then combines radar processing software, AIS (or ADS-B) and satellite positioning to jointly complete the detection, positioning, tracking and recognition of targets. In the radar camera linkage solution we provide, the radar can be primary radar, AIS, ADS-B or fusion radar tracking data. The linked cameras must conform to the Pelco-D protocol or Chess protocol.
Scheme composition
The perimeter security scheme consists of radar, radar processing software and photoelectric system. The operating principle of the system is that the radar can search in the detection area to obtain the surrounding target information, and the radar information processing system can process the radar image of the time series, and automatically identify, track and calculate the motion parameters of the target echo in the image.
The radar system, which can identify vehicles, people and even small animals, uses very little energy and can be powered by batteries or solar energy without the need for additional power lines. High standard waterproof and dust-proof design, can ensure normal work in bad weather, dust and gas without the need for frequent cleaning.
The ASD radar processing software can be customized to separate areas of no warning, warning, and emergency warning, and can detect targets moving normally, targets moving illegally, and vehicles or people parked illegally. When the radar finds the suspicious target, the software can automatically mobilize the surrounding cameras to track and shoot the image of the suspicious target, which can realize the integration of CCTV video monitoring system and radar monitoring. When a suspicious target is detected, the user can send out a picture and sound alarm without any action at all, and the camera can automatically track the target.
Front-end acquisition part: Because the remote photoelectric turntable adopted by the system integrates thermal imaging and auxiliary light source, the corresponding target image can be obtained even at night. This airport scheme adopts PT series.
For the tracking target locked by the radar, the system will automatically input the position coordinate of the corresponding target into the PT remote photoelectric turntable, and the coordinate directly corresponds to the preset point of the remote photoelectric turntable. The motion tracking of the target adopts the way of video analysis, the platform software drives the remote photoelectric turntable to carry out continuous tracking and shooting, and the motion track of the target is displayed on the software map. At the same time, the real-time image of the moving target will also be displayed in the software interface.
System advantage
Radar target tracking
Compared with the surveillance mode only with cameras, radar perimeter security coverage is wider, and is not affected by dust, haze, rain, light intensity and other harsh environment. Monitoring personnel can inform each department to prepare for security in advance. The false alarm rate is very low, perhaps one every 24 hours.
The radar target tracking module can be done as a stand-alone SPx Server or integrated into custom development or framework development services. Within the range of radar coverage, automatic target tracking can be completed. The target register is a highly configurable software module, which can be configured according to different radar types, tracking target size and application scenarios. The tracking report can be sent to the network to control the camera to follow and track the target.
The radar main interface provides the situational awareness map of the whole monitoring area, through which the target activity in the area can be clearly observed. The highlighted area allows you to view the overall picture while viewing the details in the small window below. The camera main screen displays the picture captured by one camera. The small window below allows you to switch between multiple Windows. The radar tracking function and tracking data fusion function are also included in the system. The fusion data includes primary radar tracking, AIS and ADS-B information. In addition to the alarm for the target of the offending movement, the software will also trigger the alarm if certain ADS-B or AIS messages do not conform to the regulations (not friendly targets).
