Abstract
Techniques are disclosed for providing vehicular radiometric calibration systems and methods. In one example, a method includes capturing, by an array of infrared sensors mounted on a vehicle, a thermal image of a scene during navigation of the vehicle and/or while the vehicle is stationary. The thermal image comprises a plurality of pixel values. Each infrared sensor of the array is associated with a respective one of the plurality of pixel values. The method further includes determining temperature data associated with a portion of the scene, where the portion is associated with a subset of the plurality of pixel values. The method further includes generating a correction value based on the thermal image and the temperature data. Related systems, vehicles, and devices are also provided.
