Abstract
A radiometric camera and method for obtaining accurate radiometric readings of objects in a scene captured by a radiometric camera. The method comprises estimating a gamma drift coefficient based on an input thermal image, wherein the thermal image is captured by an infrared sensor; performing, based on the gamma drift coefficient and the input thermal image, a sensor temperature stabilization to provide an ambient-stabilized thermal image, wherein the ambient-stabilized thermal image is invariant to temperature changes of the infrared sensor; performing ambient calibration to estimate a scene temperature based on the ambient-stabilized thermal image; and measuring, based on the estimated scene temperature and a calibrated attenuation factor, a temperature of each of at least one object shown in the input thermal image, where the temperature of each of the at least one object is measured independently of the ambient temperature of the radiometric camera.
