Abstract
A high-speed, high-resolution, triangulation-based, 3-D method and system for inspecting manufactured parts and sorting the inspected parts are provided. The method includes consecutively transferring the parts so that the parts move along a path which extends from a supply of parts and through an imaging station. A triangulation-based sensor head is supported at the imaging station. The sensor head is configured to generate focused lines of radiation and to sense corresponding reflected lines of radiation. The focused lines are delivered onto an end surface of each part to obtain a corresponding array of reflected lines of radiation. The sensor head senses the array of reflected lines to obtain a corresponding set of 2-D profile signals. The set of profile signals represent a 3-D view of the end surface. The set of 2-D profile signals of each part is processed to identify parts having an unacceptable defect.
