  • Radiometric correction and alignment techniques for thermal imager with non-contact temperature sensor
    Patent number: 10598550
    Abstract: Various techniques are provided for calibrating a thermal imaging device using a non-contact temperature sensor. In one example, a method includes capturing a thermal image of a scene. The thermal image comprises a plurality of pixel values. The method also includes detecting, by a non-contact temperature sensor, a temperature value associated with a portion of the scene corresponding to a subset of the pixel values. The method also includes comparing the subset of pixel values with the detected temperature value. The method also includes generating a correction term based on the comparing. The method also includes applying the correction term to at least the subset of pixel values to radiometrically calibrate the subset of pixel values. Related systems and alignment processes are also provided.
