A New Method of Strip Velocity Detection Based on Linear CCD Image Process

This paper gives a new method to measure the speed of strip based on linear CCD. For the surface of any strip, the image signal collected by linear CCD can be seen as image with strip feature by accumulating for a while, and the directivity of the strip relate to the speed of the strip. The power spectrum of the strip image can reflect the degree of thickness and the directivity of the strip. So the speed of the strip can be obtained though analyzing the power spectrum of the strip image.
