ABSTRACT:
A method and apparatus are disclosed for determining the spatial coordinates of a workpiece including: a planar light source for illuminating the workpiece; an electronic imaging device adapted to view the intersection of the planar light and the workpiece; pulse signals including pulses representative of said intersections; and a device for determining the centroid of the pulse by integrating the pulse signal over a selected interval including the pulse, integrating the result of the first integration in like manner and dividing the result of the second integration by the result of the first integration.
