1. An imaging system comprising:
a memory storing instructions which, when executed by processing circuitry, cause the processing circuitry to perform operations comprising:
receiving first image information including an image of an object, using a first camera calibrated using a first group of photometric parameters;
determining, using the first camera, first luminance information associated with the first image information;
receiving, using a radar unit, radar information indicating the object;
determining based upon the radar information, a speed to associate with the object; and
adjusting one or more values of the first group of photometric parameters based upon the first luminance information and the speed of the object.
