With the expanding of domestic military technology pilot work and in-depth, more and more military technology to civilian markets, such as unmanned aerial vehicle (uav) in the absence of market blowout, at present, although the thermal imaging technology is now developing more gently, but with the increase of requirements for security technology and lower production costs, thermal imaging technology in more industries. Security monitoring, forest fire early warning and from the city to the building energy and high temperature test, high speed railway safety monitoring, vehicle safe driving cars and consumer products (smart phones, outdoor use website, etc.), and other fields. According to incomplete statistics of infrared thermal imaging technology in China market potential demand of up to 500-500 yuan, and the current market situation is only in its infancy, in 2020, the infrared thermal imager market will grow by more than 20%.
Infrared thermal imaging technology is emerging
In our daily life, in addition to our video monitoring using visible light visual sensor, and various sensors are used by human perception, to extend and supporting our awareness, thermal sensing imaging sensor is undoubtedly one of the very valuable.
The past few years have seen the rapid development of thermal imaging and its applications as high-end surveillance. Thermal imaging is used to detect electromagnetic waves from infrared wavelengths that the human eye cannot perceive. Nature, there are always more than absolute temperature 0 ℃ (273.15 ℃) objects can produce thermal radiation, including radiation human body infrared wavelengths of 3 ~ 50 m, of which 8 ~ 14 m accounted for 46%, maximum radiation appeared at about 9.5 m. The image processed by infrared detector is called thermal image, because different objects and even different parts of the same object have different radiation ability and their reflection on infrared radiation is different. Using the object and the background environment radiation differences and the differences of itself parts and radiation, thermal image of each part and radiation can be ups and downs, which can show the scene of heat distribution state.
Compared with the traditional optical camera rely on natural or environmental light for video surveillance, and thermal imaging camera without any lighting, rely on the object itself can clear imaging infrared heat radiation. Thermal imaging cameras are suitable for any lighting environment, not affected by the glare of the light, and the target is clearly detected and detected by day and night, identifying camouflage and hidden targets. Therefore, it is possible to realize 24-hour monitoring of day/night.
Atmosphere, clouds of smoke will absorb the visible light and near infrared, but for 8 ~ 14 microns (long wave infrared area) of thermal infrared is transparent, it is difficult to make in the clouds are gathering of traditional cameras captured under the environment of clear images, while thermal imaging camera can effectively penetrate the atmosphere, clouds and other shoot the clear image of the environment.
Infrared thermal imaging camera can show the object temperature field, the human eye cannot see directly target surface temperature distribution, become the representative of the human eye can identify the target surface temperature distribution of thermal images. In acquiring the thermal image of the object at the same time, through the thermal imaging system intelligent temperature measurement algorithm for non-contact detect infrared heat energy quantization and calculation, can be the object surface temperature, relatively accurate measurement can be used for temperature early warning surveillance occasions, prevent fire caused by the change in temperature, such as electric power, petrochemical industry, forest fire prevention, etc.
Smart city burst point
Infrared thermal imaging have made a good performance in many areas, but the thermal imaging technology in the security industry has not emerged, with the advent of intelligent city, the situation may be changing.
First of all, the wisdom city dependence on monitoring will reach a new level, the traditional optical camera rely on natural or environmental light for video monitoring, it is difficult to meet the full range of intelligent city, all-weather image information needs, and the thermal imager without any light, rely on the object of infrared heat radiation can enlarge the advantages will be further clear imaging, day or night can clearly target detection and discovery, the real wisdom city smooth running 24 hours a day.
Secondly, the fusion of thermal imaging technology and many new technologies will also reach a new height and better service smart city construction. Such as the combination of thermal imaging and unmanned aerial vehicles, it can be used more widely in disaster relief, catching criminals, power patrol, scientific shooting, industrial and agricultural production, etc. Combining with intelligent transportation, it can effectively relieve road traffic pressure, and can provide real-time road traffic information to assist driverless cars on the road. It can also be widely used in urban public place monitoring to effectively identify hidden targets of dark and shade environments and reduce the probability of public safety incidents. It can be said that thermal imaging is like a big umbrella for smart cities, escorting smart cities and providing shelter for urban residents.
