Modeling and Calibration of Variable-Parameter Camera Systems

Camera systems with adjustable lenses are inherently more useful than those with fixed lenses. Adjustable lenses enable us to produce better images by matching the camera’s sensing characteristics to the conditions in a scene. They also allow us to make measurements by noting how the scene’s image changes as the lens settings are varied. The reason adjustable lenses are not more commonly used in machine vision is that they are difficult to model.
