Thermal Imaging Technology Is Used In Airport Security
In recent years, the airport aviation business has developed rapidly. The flow of people at the airports and ports of entry and exit in various countries is large and the situation is complicated. This has resulted in a very heavy task of security inspections for entry and exit personnel. Airports and customs are special places. It is easy to monitor and track targets with ordinary cameras during the day.
But at night, ordinary cameras have certain limitations. This is because ordinary cameras use visible light for imaging. However, the imaging effect is not good at night or in a poorly lit environment, which may lead to false alarms. The use of infrared thermal imaging cameras can easily solve this problem. Since the global outbreak of COVID-19, the traditional body temperature safety monitoring model has been unable to meet the safe and smooth passage of domestic or inbound and outbound passengers at airports, customs, etc. The body temperature monitoring system using infrared thermal imaging technology can effectively improve the passage efficiency of passengers.
1. Airport perimeter security
The airport perimeter anti-intrusion system is the first line of defense of the airport security system. At present, airport security measures are mainly concentrated in the terminal building, including air defense, technical defense and physical defense. This has formed a heavily guarded and well-functioning terminal security system. However, the security of the perimeter of the apron, which is more than ten or even dozens of kilometers long, has not been paid enough attention, and there are great hidden dangers, which is the weak link of the airport security system. In recent years, there have been several incidents of intruders climbing over the airport fence and infiltrating the interior of the aircraft in many countries, posing a serious threat to airport security.
Disadvantages of video surveillance:
- Lack of alarm function. It can only play the role of post-event tracking. Although intelligent video technology has been added later, the false alarm and missed alarm rate are too high to be applied on a large scale.
- It has strong environmental constraints. It cannot be used in weather conditions such as dark night, heavy rain, heavy fog, and heavy snow.
- The monitoring personnel are easily fatigued. According to statistics, if the security personnel continuously monitor for more than 20 minutes, they will “turn a blind eye”.
The use of infrared thermal imaging technology can make up for the shortcomings of traditional video surveillance. Infrared thermal imaging technology can achieve all-weather real-time monitoring, and clearly see the surrounding conditions and potential safety hazards under harsh conditions such as darkness, smoke, and fog. It can be integrated into the infrared thermal imaging PTZ camera, equipped with functions such as preset position, scanning, cruise, etc., to realize day and night visual monitoring in the jurisdiction and night vision monitoring in key areas. It can observe the live real-time images of multiple monitoring points at the same time, and carry out 24h unattended, automatic monitoring, alarm linkage and trigger video, SMS, email and other alarms, as well as automatic tracking and positioning of the intruder trajectory. For the security and quarantine departments to grasp the dynamics of the jurisdiction, timely prevent the further occurrence of intrusion and the occurrence of bad consequences. Infrared thermal imaging technology can also be installed on turnstile gates to intercept intruders at the entrance.
2. Inspection and Quarantine
In recent years, with the prevalence and raging of COVID-19, traditional inspection and quarantine work has faced increasingly severe challenges. In order to ensure the safe and smooth customs clearance of inbound and outbound passengers under the new situation, innovative thinking and innovative methods need to be adopted. Using an infrared body temperature monitoring system with a higher degree of automation is a better technical choice.
Infrared thermal imaging technology can perform non-inductive infrared human body temperature screening for all people who pass through the temperature measurement door. Once the target whose body temperature exceeds the standard is detected, it will automatically alarm and take pictures to keep. The latest infrared thermal imaging system uses deep learning algorithms based on neural networks.
The temperature measurement is more accurate, the false alarm rate is lower, and the accuracy is less than or equal to 0.5°C. It can check the feverish people in the crowd in a large area, improve the efficiency of epidemic prevention and control, and greatly reduce the risk of infection. For airports, such non-sensing security checks are especially suitable for rapid security checks in the form of large passenger flows. The non-contact temperature measurement method is adopted to effectively avoid cross-infection.
