Overview of Infrared Thermal Imaging Technology
Infrared thermal imaging technology converts invisible infrared radiation into visible thermal images, displaying the temperature differences of target objects. As a passive, non-contact detection technology, infrared thermal imaging offers advantages such as night vision, remote detection, darkness penetration, and resistance to interference, widely used in electric power inspection, security surveillance, gas leak detection, intelligent driving, and more.
However, due to environmental factors, infrared images often suffer from issues such as low contrast, blurry details, and high noise compared to visible light images. This requires the use of specialized image processing algorithms for correction and optimization.
Core Image Processing Algorithms
1. Non-Uniformity Correction (NUC)
Due to material and process differences, the thermal resistances of the infrared detector's focal plane units are often inconsistent, resulting in uneven imaging. Through non-uniformity correction algorithms, we can correct these discrepancies and improve the uniformity and quality of infrared images.
2. Adaptive Gain Control (AGC)
Dynamic range compression is one of the basic algorithms in infrared thermal imaging, automatically adjusting the brightness and contrast of the image based on different scenes, making the image's details clearer and easier to observe and analyze.
3. Dynamic Detail Enhancement (DDE)
DDE is a nonlinear image processing algorithm designed to preserve the details in high dynamic range images. It allows even in extreme temperature scenes, the details of target objects remain visible.
4. 3D Digital Noise Reduction (DNR)
3D DNR analyzes adjacent frames to automatically remove noise, significantly enhancing the image's clarity and delicacy. It is particularly useful in environments with significant noise, ensuring that infrared images remain pure and clear.
5. Isothermal Mode
Isothermal mode is an image processing technique in infrared thermal imaging that uses pseudo-color to highlight specific temperature ranges within the infrared image. This algorithm emphasizes the temperature differences, making it easier to quickly identify and analyze target areas. It is particularly suitable for applications requiring precise observation of temperature changes, such as high-temperature alarms and hotspot monitoring.

6. Area Analysis
Area analysis algorithms divide the infrared image into regions and automatically detect the temperature characteristics of each region. These algorithms calculate the maximum, minimum, cursor, and average temperatures of the area, providing detailed temperature information for further analysis. Additionally, when the temperature within a region exceeds a set threshold, the system will automatically trigger an alarm or start hotspot tracking, ensuring real-time monitoring of the target.
