摘要： A method of and apparatus for discriminating sharp edge transitions produced during optical scanning, as by a CCD or the like, of differently reflective regions of a surface, such as copper conductors and resist background on printed circuit boards and similar applications, through delaying N successive sampling signals defining the edge transition of the desired edge transition regions slope and amplitude from unwanted reflections from other regions, subtracting each camera scan sampling signal from the previous Nth sample signal to produce a large difference signal only for the edge transitions, and adding such difference to the camera output signals to provide a distinctive boost to the edge transition signals which are then thresholded in a manner to insure rejection of signals from unwanted or spurious reflection regions into binary output signals unambiguously indentifying the edge transitions.

摘要： A first linear sensor tracks the movement of an object through an inspection station and a second linear sensor views the object transverse to the object path to acquire a line image of the object, and a synchronizing arrangement responds to the sensed position of the object to trigger the second sensor at spaced object positions to obtain a plurality of line images which cummulatively represent the object image. The image is compared, line-by-line, as acquired with a stored model of the object to determine the correlation between the object and the model.

摘要： An apparatus and method is shown for measuring the shoe length of a video disc stylus and displaying a digital representation of the measured value in standard units of length for viewing by a human observer. The apparatus utilizes a video slicer for providing a selectively positionable sampling line on the screen of a monitor which displays an image of the part to be measured. The sampling line is positioned directly over the part to be measured and a signal is generated having a pulse amplitude corresponding to the brightness of the image only along the sampling line, and having a pulse width corresponding to the length of the image along the sampling line.

摘要： The invention proposes an electro-optical measurement system to be used to measure the width and possibly also the thickness of a strip 14 being rolled. The strip is imaged onto an electro-optical transducer each of which views the whole width of the strip. To compensate for inaccuracies resulting from the imaging system, a calibration of the imaging system is effected by means of a grid of known dimensions. The calibration results are recorded during a setting up process and used by a digital or analogue computer to correct any measurements taken by the imaging system during operation. There is also disclosed an improved technique for edge detection and for processing video data in real time.
