With the miniaturization of smart device hardware modules, thermal imaging products can be applied to smart buildings, even smart phones, in addition to drones.
After several decades of development, infrared thermal imaging technology has been widely used in military, medical, industrial production, fire protection and other fields, and in recent years, the development trend of civilization has been opened. For security, the emergence of thermal imaging technology has increased the role of night vision and perspective for video surveillance in the absence of light, playing a vital role in the development of the entire security industry. With the continuous innovation of technology, nowadays, thermal imaging technology is constantly developing towards new applications and new fields. Today we will talk about the sparks of the combination of thermal imaging technology and drones and intelligence.
The principle and development of infrared imaging All objects in the natural world, as long as the temperature is higher than the absolute zero (-273.16 ° C), will emit infrared rays, using infrared detectors and optical imaging objectives to detect, you can the infrared radiation energy of the measured object The distribution pattern is reflected on the photosensitive elements of the infrared detector to obtain an infrared thermogram that converts the invisible infrared energy emitted by the object into a visible thermal image.
At the beginning of the 19th century, British physicists discovered infrared radiation from mercury thermometers. Until the twentieth century, infrared detection technology was continuously improved. Throughout the history of infrared thermal imaging technology, it has completed the detection of chilled infrared by photon Danyuan. The development of focal plane array imaging to non-cooled infrared imaging. And its application as early as the beginning of the Second World War, thermal imaging technology has been applied to the military, using thermal radiation to detect the enemy's whereabouts. Later, with the advent and popularity of thermal imagers, they were gradually used in medical, industrial production, and daily life.
Thermal imaging + drone 　 As the hottest technology single product, drones have already set off a wave of “UAV+†in all walks of life. At one time, Internet giants such as Google, Amazon, and Facebook have entered the hottest high-profile. The machine industry has formed a batch of drone products. Domestic drone manufacturers headed by Dajiang have already occupied an important position in the global market. After the professional-grade drones were exhibited in the security industry in Shenzhen last year, major security brands have also been The technical development of the machine is eager to try, and the security industry is also deeply immersed in the "UAV+" trend.
Like the Internet, drones can determine the functions they have based on the equipment they are equipped with, opening up a channel for cross-border cooperation with traditional industries, and as the number of applications for drones continues to increase, the technical requirements are constantly Intensified, infrared thermal imaging technology has become an important technical guarantee for drones in disaster relief, arresting criminals, power line inspection, scientific shooting, industrial and agricultural production. The cooperation mode of drone + infrared thermal imaging also makes infrared thermal imaging technology more stereoscopic and diversified.
Based on the technical integration of thermal imaging technology and drones and broad application prospects, DJI announced that it has cooperated with FLIR, the global leader in thermal imaging, to launch night vision drone products. A model of cross-border cooperation between man-machine + thermal imaging. As a domestic thermal imaging brand enterprise, Dali Technology, Wuhan Gaode, Guangzhou Kate, Shanghai Giant, Shenzhen Jingyang, etc. have also begun to explore the drone.
Along with the maturity of the electronics industry, materials science, control and communication technology, UAV + thermal imaging will be widely used in various industries, opening up a period of rapid development of the industry. The drone can be equipped with a visible light camera and an infrared camera for aerial photography. It is not limited by space and geographical location. The thermal imager can detect the temperature distribution of the scene by detecting the infrared rays emitted by the object itself, which can be low in visibility and dangerous. Position detection, the overlap of the two technologies can be used for night vision tracking, search and rescue, equipment inspection, agriculture, forestry, animal husbandry and fishery, etc., especially in some disaster prevention and monitoring, but also play an important role.
Thermal imaging + intelligent video surveillance has gone through the development process from human duty, identification analysis to automatic machine analysis. It has completed the gradual transition from after-the-fact retrieval to automated and intelligent identity transformation. The intelligent analysis technology enables the monitoring equipment to have the capability of self-awareness, image recognition and deep learning, and extends the after-the-fact forensics of security monitoring to pre-warning, rapid handling of the matter, and retrieval of the evidence chain after the massive data, thus greatly improving the monitoring. effectiveness. Adding intelligent analysis function to the infrared camera, the manpower is liberated to the utmost extent. At present, it not only realizes the efficient analysis and fusion application of event results, but also forms the output of the internal law of the event, assists scientific decision-making, and quickly solves the actual problem. problem.
To combine thermal imaging with artificial intelligence to extend the scalability of thermal imaging technology, FLIR integrates its world-leading Long Wave Infrared (LWIR) technology with Movidius' industry-leading vision processing unit (VPU) into a thermal imaging core. It enables advanced image processing at low power consumption, bringing artificial intelligence to its thermal imaging products.
In China, many infrared thermal imaging cameras have added the function of intelligent analysis. Compared with the traditional visible light camera, Dahua Wang Kaifeng believes that "infrared thermal imaging cameras have strong penetrating ability, long detection range, and can be recognized and hidden. Advantages such as target, temperature detection and day and night visibility have formed an indispensable complementary relationship with visible light cameras in the field of security surveillance. Infrared thermal imaging cameras based on image and temperature algorithms have greatly improved the accuracy of alarms and security systems. Operational efficiency, which is steadily promoted in perimeter security, airport security, and railways, the front-end intelligence has become the future and trend of the entire industry."
In addition to intelligent analysis, the future of thermal imaging will be more intelligent development, achieving the goal of "professional intelligence" such as intelligent perception, intelligent recognition, intelligent analysis, intelligent tracking, intelligent linkage, intelligent integration, intelligent assistance, and intelligent control.
With the miniaturization of smart device hardware modules, thermal imaging products can be applied to smart buildings, even smart phones, in addition to drones. With the development of civilization, it is believed that more military technologies will fully penetrate into the civilian market and support core technological breakthroughs.
