ABSTRACT:
A system for creating a image of the surface contours of a metal workpiece, such as a continuous cast slab, is provided including a sheet of single frequency, planar light is directed to strike a surface of the workpiece, and a video camera positioned to view the surface where the light strikes, such that when the surface of the workpiece is flat, a straight line is sensed by the video camera, when the surface is irregular, the video camera senses a nonlinear line, the video camera creates a two dimensional image of the sensed light and supplies this signal to a processor, which then creates an image of the workpieces which is displayed by a video monitor and a printer. The processor extracts a variety of quantitative parameter values from the images.
