Abstract

PURPOSE:To extract a shape precisely in detecting the shape by extracting data on external circumference edges from the radiant light distribution of a red- heated steel plate, by using three kinds of windows which conform to the external circumference shape in processing the shape by track arithmetic. CONSTITUTION:Radiant light from a red-heated steel plate is detected to obtain the digital value of each part of the steel plate which corresponds to temperature distribution, and this data is processed by temperature histogram arithmetic to eliminate a blur due to the scattering, etc., of the external circumference part of the steel plate. Then, the edge parts of the external circumference are emphasized by spatial differential arithmetic and the edges are processed by track arithmetic to detect the deformation of the front and rear end parts of the steel plate. Then, the representative front end parts A-C of the steel plate are divided into three areas P-R and three kinds of windows M1-M3 which have directional weight coefficients W1-W4 (W1>...>W4) correspondingly are set, thereby tracking the edge parts. The windows have the maximum weight coefficient W1 in the advance direction, so tracking is facilitated.
