20130200157 | SYSTEM AND METHOD FOR EXPANSION OF FIELD OF VIEW IN A VISION SYSTEM - This invention provides a system and method for expanding the field of view of a vision system camera assembly such that the field of view is generally free of loss of normal resolution across the entire expanded field. A field of view expander includes outer mirrors that receive light from different portions of a scene. The outer mirrors direct light to tilted inner mirrors of a beam splitter that directs the light aligned with a camera axis to avoid image distortion. The inner mirrors each direct the light from each outer mirror into a strip on the sensor, and the system searches features. The adjacent fields of view include overlap regions sized and arranged to ensure a centralized feature appears fully in at least one strip. Alternatively, a moving mirror changes position between acquired image frames so that a full width of the scene is imaged in successive frames. | 08-08-2013 |
