Abstract
Systems for monitoring an inventory condition of objects based on captured images are described. An exemplary system includes at least one storage drawer, each storage drawer including a plurality of storage locations for storing objects, wherein each drawer is associated with an identifier with known color attributes; and an image sensing device configured to capture an image of one of the storage drawers along with the associated identifier. A data storage device of the system stores, for each storage drawer, information of the known color attributes of the associated identifier. A data processor of the system is configured to access information of the known color attributes of the identifier associated with the drawer corresponding to the captured image; determine color attributes of the identifier in the captured image; determine a correction factor based on the color attributes of the identifier in the captured image and the known color attributes of the identifier; and apply the correction factor to subsequent images captured by the image sensing device.
