Gain switching techniques for thermal cameras

Abstract:

Described herein are systems and computer-implemented methods for controlling a gain state of a thermal camera. According to an example method, a processor can obtain, from a thermal camera, temperature readings for respective pixels of a plurality of pixels of an image captured by the thermal camera, and the processor can determine respective weights for the temperature readings using a weight function. The method can also involve the processor determining a weighted average of the temperature readings using the temperature readings and the respective weights for the temperature readings. Further, the method can involve the processor determining based at least on the weighted average, a gain state for the thermal camera, and the processor causing the thermal camera to operate in the gain state.
