摘要： PROBLEM TO BE SOLVED: To provide a camera system that automatically compensates for a flange focal distance error regardless of the type of lens.SOLUTION: The present invention provides a method and camera assembly using a machine vision system. The camera assembly comprises: a support structure forming a mounting flange that is configured for coupling with any of a plurality of exchangeable electrically controllable adjustable focal length lens assemblies; a two dimensional image sensor supported by the support structure and forming a two-dimensional sensor plane separated from the mounting flange by a flange focal distance; and a processor programmed with a flange focal distance error and to use the flange focal distance error to generate lens control signals to compensate for the flange focal distance error when a lens is mounted on the mounting flange.
