Abstract

Method has the following steps: measurement of the distance profile of the objects in a measurement plane (5) from a fixed point measurement device (1) that is to one side of the object palette (2). The distance profile yields a contour line of the objects from the measurement point that is then used for computer fitting to circle shapes. The center of each circle is used to determine object location. An Independent claim is made for an optical device for determination of cylindrical object position. The distance measurement device is a CCD triangulation sensor.
