    Abstract: A method for inspecting garments for holes includes front-lighting the garment against a contrasting background and forming a pixel image thereof, isolating garment pixels from background pixels by automatically selecting an optimum binarization threshold grey level, binarizing the image at that level, determining the garment boundary, testing for consistency of grey level within the garment boundary on the binarized image along rows and columns of pixels within the garment boundary and noting inconsistent pixels, and identifying as holes only pixels which have been noted as inconsistent in both horizontal and vertical tests.

    Abstract: A part scanning and part calibration apparatus and mechanism for the inspection of printed circuit boards and integrated circuits include a camera and two rotating mirrors to scan an image of a pattern mask retical upon which a precise pattern has been deposited. Small parts are placed upon the retical to be inspected. The third overhead mirror is provided to view the part under inspection from another perspective. The scene of the part is triangulated and the dimensions of the system can thus be calibrated. A precise retical mask is provided with dot patterns which provide an additional set of information needed for calibration. By scanning more then one dot pattern the missing state values can be resolved using an iterative trigonomic solution.

    Abstract: As an object moves along a conveyor (A), a position sensor (B) generates a trigger signal. The trigger signal causes a strobe (14) to emit a high intensity flash of light into an examination region. A lens (20) of a CCD camera (C) focuses light from the examination region both before and during the flash on an image section (24) of a CCD array (22). Subsequent to the flash, a trigger signal delay circuit (16) causes a control circuit (D) to shift the lines of pixel values from the image section into a storage section (26), from the storage section to shift registers (32), and serially from the shift register as a video signal. A video signal channel (52) refines the video signal which is transferred to a computer system (E) which implements a preselected quality control algorithm selected in accordance with a product to be examined. The control circuit includes a pulse generator (74), which provides the appropriate clocking pulses to transfer the data among the image section, the storage section, and the shift registers. A line counter (80 ) counts the lines of pixel values transferred from the image section. When the count corresponds to one field of a video image, the counter causes gates (96, 98) to stop passing clock pulses to the image and storage sections for transferring pixel values therebetween.

    Abstract: An optical inspection system for tubular products utilizes a feeler for engaging the internal surface of the tube to be inspected and a miniature charge coupled device video camera for viewing the interface between the feeler and the tube. An image processing computer responsive to the output of the video camera produces information for rapidly assessing damage or distortion of the tube. The camera is pulled or pushed through the tube while continuously monitoring the optical contrast between the feeler and the tube wall. The camera image of the tube ID is fed to the image processing computer to determine and record changes in ID contour is a function of the axial position of the camera and feeler. These data in turn can be used in tubing life prediction considerations. The data may be analyzed manually if desired.

    Abstract: Automated inspection of solder bumps (18--18) on a major surface (14) of a chip carrier (10) is accomplished by placing the chip carrier on a platform (22) beneath a ring light (28) which is in registration with a television camera (30). Light from the ring light, which is directed at an angle towards all sides (12--12) of the chip carrier, is only reflected upwardly into the television camera by the solder bumps. The output signal of the television camera, which varies with the intensity of the light reflected from the solder bumps, is processed by a vision system (32) to obtain a one-dimensional plot of the light intensity. The one-dimensional intensity plot is analyzed automatically by the vision system to detect for missing, bridged or excessive solder bumps on the chip carrier.
