1. Resolution and detail recognition: The higher the pixels of the thermal imager, the higher the image resolution, and the richer and clearer the details that can be recognized and displayed. It is generally used for long-distance target recognition and tracking, with 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 the thermal signals of targets behind or far away from the occlusion. Typical thermal sensitivity is 50mK or below.
3. Image noise: The lower the image noise, the clearer and smoother the image, and the higher the recognizable details. High-quality thermal imagers can effectively control and reduce image noise and ensure image quality.
4. Image inhomogeneity: The performance of each part of the image should be consistent, without obvious image blur, dark area or distorted area. High-quality thermal imagers can provide uniform and consistent images.
5. Accessories quality: High-quality thermal lenses, window materials, image processing software and other accessories help maximize the performance of the thermal imager and obtain clear and realistic thermal image images.
6. Imaging effect: Whether the final thermal image effect is clear, smooth and real. High-quality thermal imaging systems 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 short, judging thermal image quality mainly considers pixel resolution, thermal sensitivity, image noise, image inhomogeneity, accessory quality 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 provide
