열화상 기술이란?

 

가시광선 스펙트럼은 실제로 물질을 투과하는 감지 가능한 대형 신호 대역 또는 파형의 일부에 불과합니다. 전자기 스펙트럼은 각각 고유한 파장을 가지고 있는 다양한 비가시파 유형의 방사선을 포함합니다. 적외선 방사(IR)는 이러한 특성 중 하나로 가시광선보다 파장이 길기 때문에 일반적으로 육안으로 확인이 불가능합니다. 

절대 0도보다 높은 온도의 물체는 감지 가능한 양의 IR을 방출합니다. 물체의 온도가 높을수록 IR이 더 많이 방출됩니다. 열화상 카메라는 물체 사이의 온도 차이를 활용하여 보이지 않는 IR을 열 영역 이미지의 형태로 "보이게" 합니다.

ADVANTAGES OF THERMAL IMAGING

Unrivalled Adaptability

The image reproduction of thermal cameras is not affected by lighting conditions - either extremely low light or even no light at all. And compared with imaging with visible light, thermal cameras are much less impacted by weather conditions such as fog, smog, rain and snow, so that they can work in virtually any environment, anytime.

 

Video Content Analysis

Thermal imaging has an intrinsic advantage for video content analysis (VCA) – it renders objects with clear outlines that stand out pretty well against the background, even at great distances. Users can easily set up VCA rules to detect actions such as line crossing, intrusion, region entrance, and region exit with high accuracy.

APPLICATION SCENARIOS OF THERMAL IMAGING
Perimeter Defense
  • Superior Environmental Adaptability
    Thermal products are capable of capturing images all day and night, regardless of environmental factors such as darkness, bright light, backlight, fog, and haze.
  • Extended Distances
    Compared to optical cameras, thermal detection covers much longer distances and requires fewer devices to install.
  • Better Visuals
    With thermal cameras, you can easily discover objects and potential risks otherwise invisible to normal cameras. In addition to thermal images, the built-in visible-light module can provide supplementary recorded evidence – lowering costs for installation.
Fire Detection
  • Temperature Anomaly Detection
    Thermal cameras can detect abnormal temperature in key areas and trigger alarms in the first place to prevent fires.
  • Dynamic Fire Detection
    If an area’s temperature is undetectable or fire already starts, thermal cameras can also detect fire at early stages by a dynamic fire detection algorithm.
Temperature Measurement
  • Heat Distribution Display
    Thermal cameras transform invisible infrared radiation of target objects into a visible, heat-distribution image in real time, which helps users locate problematic areas easily.
  • Non-Contact Temperature Measurement
    By evaluating the intensity of infrared radiation emitted from objects, thermal cameras perform non-contact temperature measurement. Users can keep their operating equipment up and running throughout the inspection process, which helps technicians work safer and more efficiently.

FUTURE TRENDS

Diversified Applications

 

Rapid technological changes in thermal imaging recently has led to a decline in the cost of thermal products along with a rapid expansion in their applications across industries. Thermal imaging has gone from niche to public markets in a relatively short period.

Thermal imaging is rapidly expanding from its conventional applications in military, law enforcement and temperature measurement to new domains such as forest fire prevention, crop burning monitoring, indoor fire prevention, perimeter defense, border defense, coast defense, and intelligent transportation. Full use of its environmental adaptability and long-range detection capabilities is coming into focus.

This booming market is benefiting from a full range of technological innovations – such as detectors, lenses, and SoCs – along with innovations in the manufacturing processes. Now, miniaturized, intelligent thermal products are rolling out for industrial temperature measurement, handheld temperature measurement, driving assistance, medical services, or as peripherals of drones and smart phones. Some industries even see disruptive innovations in the application of thermal technology. The diversification of applications will continue to expand the market for thermal imaging and accelerate continuous growth in this specialized industry.

Intelligent Products

 

The popularization of AI technology in recent years has also promoted technological advances in thermal imaging, as more and more deep-learning-based thermal applications become a part of people’s everyday life.

Creating deep-learning algorithms for behavior analysis, smoke and fire detection, and vessel identification, Hikvision is pioneering the fusion of thermal imaging and AI technologies to significantly improve alarm accuracy in areas such as forest fire prevention and perimeter defense. We believe that front-end intelligent diagnosis, traffic event detection and other thermal-based technologies will be applied in fields like industrial temperature measurement, human body temperature measurement, handheld temperature measurement, intelligent transportation, driving assistance, and drones.

Fused Technologies and Smart Linkage

 

When it comes to rendering images of a given resolution, infrared detectors are much more costly than the CMOS or CCD sensors. The lower pixel count transmitted from infrared detectors usually means reduced image detail. However, Hikvision’s signature thermal technology – bi-spectrum image fusion – combines features from both thermal and optical images to create a unique hybrid image that provides extra details for users in the pursuit of high resolutions and smart applications.

Adding to image fusion within a bi-spectrum thermal camera, the smart linkage of thermal cameras with IP cameras puts the advantages of both into one system. Thermal cameras provide high-precision video analytics that are unhindered by weather conditions, and IP cameras offer HD video footage and facial recognition functions to facilitate event investigation.
