Abstract:
A visual inspection system (100, 200) for optical fibers (150) includes at least a pattern source (120, 220A, 220B, 220C, 520); at least a first illumination source (130, 230A, 230B, 230C, 510, 522) to direct light towards an optical fiber (150); and at least a first camera (140, 240A, 240B, 240C, 40) positioned at an opposite side of the fiber (150) from the pattern source (120, 220A, 220B, 220C, 520). At least one image (170, 180, 190) of the optical fiber (150) is taken and a pattern visible through the optical fiber (150) in the image (170, 180, 190) may be analyzed to detect distortions in the pattern.
Abstract:
A detection system including a target object having a target object coordinate system, a tracking unit configured to monitor a position and/or an orientation of the target object and generate a target object position signal indicative of the position and/or the orientation of the target object, a camera positioned to capture an image of the target object, an orienting mechanism connected to the camera to control an orientation of the camera relative to the target object, and a processor configured to analyze the image to detect a discrepancy in the image and, when the discrepancy is present in the image, determine a location of the discrepancy relative to the target object coordinate system based at least upon the target object position signal and the orientation of the camera, and then orient the camera and laser to aim at and point out the discrepancy.
Abstract:
A covered mandrel that includes a mandrel and a covering. The mandrel has an outer surface and comprises a first material. The covering is engaged to the outer surface of the mandrel and comprises a second material different than the first material. At least a portion of the covered mandrel is configured to scatter light.
Abstract:
A computer vision inspection system disclosed for use in inspecting of rotary parts like pulley gear or bearing product with internal slots or rails to determine the fabrication quality of the functional dimension of the slots or rails with the help of inspection balls (11 ) and ball followers (43). The apparatus includes a vision system with camera (30), lens (32), lighting (35), control computer, the image capturing and imaging processing computer program, and the fixture (40) and jig system for the rotary parts and inspection balls (11 ) and ball followers (43) to ensure the inspection balls are fully engaged into the ball slots (12) or ball rail of the part during inspection. When the checking balls and followers are well engaged to the ball slot or rail of the rotary part, vision image of the inspecting field covering the rotary part and the checking ball or probe, and the fiducial mark (22) on the ball follower (43) or probe head, is captured and transferred to computer program, and then doing the image processing of the captured image to calculate out the functional dimension for the part inspected. The calculated functional dimension value for each part is further recorded into a computer database or factory information system and present into a graph and comparing to the top and bottom limit for easy product quality control.
Abstract:
A method and an apparatus for inspection of at least one surface of an object (2) having an elongated shape in a direction (X) where an illuminating device(ID), that may comprise at least two illuminators (1a, 1b) or a non-discrete light array, is arranged in the vicinity of the object. At least one image digitization device (20) is arranged for capturing images of said surface. The illuminating device is further aligned in a manner with regard to the direction (X), thereby illuminating a part of the surface of said object (2) at an angle (α, α') in a dark field and/or bright field condition, whereby defects in the said surface can be visualized and imaged. In particular 3D defects, pressure lines, dents, dielines etc. in extruded products can be detected. An image processing unit can compare captured data with stored threshold data for quality inspection and grading. If rejection is necessary, a manipulator can be controlled in accordance to this and remove rejected objects. The object and/or apparatus can be arranged for movement along direction (X).
