The role and application scenario of thermal imaging reconnaissance in outdoor search and rescue
First of all, we need to understand the working principle of thermal imaging reconnaissance. Infrared thermal imaging is a technology that converts infrared radiation invisible to the naked eye into visible images by detecting the infrared radiation of the target object, through photoelectric conversion, electrical signal processing and digital image processing. Because humans are warm-blooded animals, their body temperature is usually quite different from the surrounding temperature. Under the infrared lens, the huge difference in temperature forms a strong color contrast, thus forming a clearer human outline to help find the search and rescue target.
1. Application scenario emergency rescue
The golden rescue time for missing people is only 72 hours. In traditional rescue scenarios, once a person is found to be lost, a random carpet search is often adopted, which is inefficient in finding people and easily misses the golden rescue time. With the continuous maturity of application technology, thermal imagers have become an important equipment in modern rescue, and there are many successful application cases.
A 70-year-old man with Alzheimer's disease was lost. The mountain roads in the area where he disappeared were steep and overgrown with weeds, making it extremely difficult to find him. After the rescuers used TI60 infrared thermal imaging to conduct a search and rescue operation in the mountainous area where the old man disappeared, they detected a suspected heat source and finally found the old man in the biting cold wind.
2. Application scenarios Outdoor adventure
During outdoor adventures, the environment is complex. In fog, rain and snow, it is easy for adventure companions to get lost or lost, and it will be very difficult to find them. Infrared thermal imaging technology is based on the infrared radiation of the object itself and the radiation difference with surrounding objects. It is not restricted by visible light and is not affected by bad weather such as fog. Therefore, the human body will be higher than the outdoor environment temperature. This temperature difference is shown as a strong pseudo-color contrast on the TI60 screen, which helps to quickly locate the lost companions. TI60 can also be used to observe the outdoor surrounding environment/dangerous animals and identify possible dangers in advance.
3. Application Scenarios Night patrol
Users usually use flashlights and other lighting tools for patrols, but it is easy for intruders to detect and intentionally avoid them. In addition, the penetration of lighting is poor in foggy weather, and the range of night lighting is relatively limited. Infrared thermal imaging technology can use the temperature difference between the intruder's body temperature and the surrounding environment to form an image, so the infrared image of the person will be clearly presented on the TI60 screen, and the position of the suspicious person can be quickly located. TI60 can detect people at a distance of up to 1,400 meters, and can also observe covertly without exposing the position and actions of the guards. In addition, when livestock are lost in the dark, infrared thermal imaging can use the difference between the livestock's body temperature and the ambient temperature to form an image, intuitively displaying the livestock hidden in the grass, and after turning on the laser power indicator, it can also locate the livestock 200 meters away, making it easy to catch the lost livestock.
4. Application scenarios Police law enforcement
Just as the typical application case of infrared thermal imaging participating in the capture of fugitives, in the dense forest with complete darkness, heavy fog and heavy rain, TI60 can use the temperature difference between the environment and the human body to easily identify and locate the criminal suspects hidden in the dark jungle, secretly monitor their every move, and assist the police in search and investigation.
5. Application scenarios Border and coastal defense
my country is a major country in border and coastal defense. Border and coastal defense are an important and inseparable part of national defense. The establishment of border and coastal defense is to safeguard national maritime rights and interests and protect the security of land, sea, air and territory. Border and coastal defense monitoring is a very important topic in military security. Traditional manual border and coastal defense monitoring such as standing guard, patrolling, and lurking can no longer meet the needs of border security monitoring. With the advancement of science and technology and the personalized needs of security monitoring, various monitoring technologies have emerged. Among them, thermal imaging monitoring technology does not require lighting conditions and relies entirely on the energy and temperature difference between the target and the background to form an image. It can be observed from a distance and is particularly suitable for dark environments at night and windy, snowy and rainy weather. TI650S can monitor border areas, border and coastal defense outposts, unmanned border stations, uninhabited islands, entry and exit ports, etc., providing my country's border management with all-day, all-weather, uninterrupted information on the actual status and dynamic changes of border management, and realizing the portability, scientificity, real-time and visualization of border management.
