Abstract
An optical sensing system includes at least one electro-optical sensor having an adjustable field of view and at least one reflective member including a diffuse reflector surface positioned within the field of view of the at least one electro-optical sensor. The system also includes at least one controller configured to generate calibration parameters for the at least one electro-optical sensor based on data for at least one exposure detected by the electro-optical sensor when the diffuse reflector surface is within the field of view of the at least one electro-optical sensor. Methods for calculating the calibration parameters and for directly measuring reflectivity of objects in a scene with at least one electro-optical sensor are also disclosed herein.
