Abstract

In this presentation, the image processing technology is applied to measure the dimensions in the section of hot- rolled section steel which is traveling on the rolling line. With a light sheet intersecting the workpiece, a bright section outline can appear on its outer surface. The entire image of this outline if formed by four TV cameras which image the outline in four directions respectively. The method that how to use this image to get the measured dimensions is discussed in detail. Four kinds of rolled section steel have been measured by this method, and results in the laboratory show that uncertainty is about 0.2 mm in the measurement range of 100 mm.
