摘要： A method and system for appearance inspection of a core of a heat exchanger provided with fins and tubes, performing averaging and dynamic binarization on the imaging data to extract an image of only a tube, then calculating, with respect to the extracted tube image, a center axis across a long direction of the tube comprised of the center coordinates of the tube width direction, comparing the discovered center axis with a reference value to find the maximum displacement across the long direction of the tube, and judging the tube is a defect when the maximum displacement is greater than a predetermined threshold.

摘要： For non-contact measurement of the quantity of movement, such as the quantity of injection from a car diesel injection pump, a slit plate having a plurality of slits different in shape from each other is provided so as to be movable in predetermined directions with the movement of a position detection target portion. A measurement wave is radiated toward the slit plate, and the presence of reception of the measurement wave passing through the slits is detected on a receiving surface wider than the width of the slits in a direction of movement. The distance between a reception boundary and an end portion of the receiving surface is measured. A slit through which the measurement wave is passing is specified. The relation of the quantity of movement of the reception boundary from a reference position is calculated for every slit in advance, and the quantity of movement from the reference position is detected on the basis of the measured distance of the reception boundary and the specified slit.
