Abstract: A high-resolution imaging and processing method and system for increasing the range of a geometric dimension of a part that can be determined are provided. The method includes directing at least one plane of collimated radiation at a surface of the part. Each of the planes is occluded by the part to create unobstructed first and second planar portions of the plane of radiation. Each of the first and second planar portions has a width and contains an amount of radiation which is representative of a respective geometric dimension of the supported part to be determined. The method includes increasing the width and decreasing the intensity of the first and second planar portions imaged on a plurality of predetermined measuring areas to obtain respective elongated planar portions and to produce respective electrical signals. The electrical signals are processed to determine the geometric dimension with enhanced accuracy.

Abstract: An optical method and system for generating calibration data are provided. The calibration data is for use in calibrating a part inspection system. The method includes supporting a calibration device having a central axis and a plurality of regions which are rotationally symmetric about the axis.

Each of the unobstructed planar portions contains an amount of radiation which is representative of a respective geometric dimension of the device. The method still further includes measuring the amount of radiation present in each of the unobstructed planar portions to obtain measurement signals. The method includes processing the measurement signals to obtain calibration data for calibrating the system. The calibration data is capable of converting raw data to calibrated data.

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.

Abstract: High-speed method and system for optically measuring a geometric dimension of manufactured parts such as cartridge cases are provided. The parts are consecutively transferred so that the parts travel along a first path which extends to a vision station at which each part has a predetermined position and orientation for optical measuring. An annular, interior side surface of a part which at least partially defines a pocket such as a primer pocket is illuminated when the part is located at the vision station to generate corresponding reflected radiation signals. An optical image of the illuminated interior side surface is formed from the reflected radiation signals at a single image plane. The optical image is detected at the image plane and the detected optical image is processed to determine the geometric dimension which may be primer product diameter.
