1. Resolution and detail recognition: The higher the number of pixels of the thermal imager, the higher the image resolution, and the richer and clearer the details that can be recognized and displayed. Thermal imagers generally used for long-distance target recognition and tracking have resolutions above 640x480 pixels.
2. Thermal sensitivity: The higher the thermal sensitivity, the smaller the temperature difference that the thermal imager can detect and display, and the more sensitive the image is to temperature changes, which is conducive to identifying thermal signals behind occluders or distant targets. Typical thermal sensitivities are at or below 50mK.
3. Image noise: The lower the image noise, the clearer and smoother the image, and the more recognizable details. A high-quality thermal imager can effectively control and reduce image noise to ensure image quality.
4. Image non-uniformity: The performance of each part of the image should be consistent, with no obvious image blur, dark or distorted areas. A high-quality thermal imager can provide an even and consistent image.
5. Quality of accessories: High-quality thermal imaging lenses, window materials, image processing software and other accessories help to maximize the performance of the thermal imager and obtain clear and real thermal imaging images.
6. Imaging effect: Whether the final thermal imaging image effect is clear, smooth and real. A high-quality thermal imaging system can provide clear and detailed thermal imaging videos and images, truly reflecting the thermal distribution of the scene and the thermal information of the target object.
In summary, judging the quality of thermal imaging images mainly considers pixel resolution, thermal sensitivity, image noise, image non-uniformity, quality of accessories, and final imaging effect. A thermal imaging system with high image resolution, high thermal sensitivity, low noise, uniform and clear images, and high-quality accessories can provid
