Detecting the Shape of Hot Strip Head Area with Linear CCD

Linear CCD used in detecting the shape of hot strip head area is discussed in this paper. The idea of three dimensions coordinate corresponding to the strip shape and temperature as well as how to select the relative parameters about two value image is described.According to specifiity of hot strip a digital filter is designed. The whole systerm has good result in laboratory,and make it easier that linear CCD used in head catting of hot strip optimally.
