摘要： An apparatus configured to measure at least one physical characteristic of a threaded surface (e.g., an internally threaded surface) of an object is provided. The apparatus uses optical triangulation to perform non-contact characterization of the threaded surface. The apparatus can be used to characterize various aspects of the threaded surface, including generating the measurements required to produce a longitudinal cross-sectional profile of the threaded surface.

摘要： A screw portion inspection apparatus for inspecting, by image processing, a screw portion provided in an object. The apparatus includes an imaging section for picking up an image of a region, including a screw portion, in an object along a direction inclined with respect to a center axis of the screw portion, and obtaining a two-dimensional image of the object; an image processing section for subjecting image data of the screw portion in the two-dimensional image obtained by the imaging section to a filtering process; and a thread judging section for judging whether a thread exists in the screw portion, based on output image data, of the screw portion, resulting from the filtering process. The filtering process performed by the image processing section includes an edge detection process, and the output image data of the screw portion includes edge data in the screw portion. The thread judging section judges whether the thread exists in the screw portion, based on an amount of information in the edge data resulting from the edge detection process.

摘要： A non-contact inspection system capable of evaluating spatial form parameters of a workpiece (22) to provide 100 % inspection of parts (22) in production. The system causes parts (22) to be sequentially loaded onto an inclined track (16) where they pass through a test section (18). The test section (18) includes a length detection array (40) for measuring the length of the workpiece (22), which includes a source (43) generating a sheet of light oriented in the longitudinal direction of the workpiece (22). The profile of the parts (22) are evaluated by one or more light sources also creating a sheet of light oriented transverse to the longitudinal axis of the parts (22). Single channel photodetectors are provided for each of the sources which provides an analog output of the extent to which each sheet of light is occluded by the part (22). These outputs are analyzed through appropriate signal processing hardware and software to generate length and profile data related to the workpiece geometry.

摘要： The present invention provides a method for measuring an end portion shape of a threaded pipe or tube P, the method including: a thread axis detection step; a laser light positioning step; a laser light image capture step; and a shape calculation step. In the laser light positioning step, the light source 1 and the image capture device 2 are moved together so that: the optical axis LA of the light source is located so as to pass through a measurement point D (X1, Y1, Z1) on the thread axis A, the measurement point being located in the measurement target region within a plane NP including the thread axis; and the laser light L extends in a slit-like form within the plane.
