Abstract
High-speed, triangulation-based, 3-D method and system for inspecting manufactured parts and sorting the inspection parts are provided. A plurality of angularly-spaced, triangulation-based, sensor heads are located at an imaging station to simultaneously deliver focused lines of radiation onto a plurality of exterior side surfaces of the part during motion of the part relative to the focused lines to obtain corresponding arrays of reflected lines of radiation. The sensor heads simultaneously sense their corresponding arrays of reflected lines to obtain corresponding sets of 2-D profile signals. Each set of profile signals represent a 3-D view of one of the exterior side surfaces and the sets of 2-D profile signals represent a 360° panoramic composite 3-D view of the outer peripheral surface of the part.
