What factors affect the accuracy of thermal imaging cameras?

Several factors affect the accuracy of an infrared thermal imaging camera. Key influences include ambient temperature, humidity, and emissivity of the surface being measured. Reflections from shiny surfaces, camera calibration, and distance from the target also impact accuracy. Environmental conditions like wind and airborne particles can cause variations. The sensor quality, lens type, and software algorithms used for processing thermal data play crucial roles. Regular maintenance and recalibration are essential for ensuring consistent performance and precise temperature readings.
