ABSTRACT:
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.
