Abstract

A method of acquiring dimensional and gauge data of objects and work pieces, such as forgings or the like, uses two image producing sensors, each being up and down tiltable about a horizontal axis and swivable from side to side about a vertical axis. At least one of the sensors is directed initially towards the object for acquiring position data on a particular point of the object such as a point of intersection of two contrast lines. One of these sensors is then positioned, including tilting and/or swiveling until a particular image field point coincides with the intersection point whereupon the other sensor has a particular image field point trained on that same particular intersection point. Finally, dimensional and guage data of the object is derived from angular position data of multiple points as so acquired by the two sensors.
