Abstract: A new measuring method and a technical scheme of recognition system are proposed, which estimate the BOF final point by analysing the texture features of the flame images obtained from converter vessel mouth. Major work include the flame images collecting, preprocessing, computing and selecting the texture features, and analysing and comparing these features. An application program was also worked out. According to the data obtained from experiment, it is demonstrated that this method and technical scheme are feasible. The scheme avoids the difficulty of complicated mechanism modeling, has no request of the vessel mouth size, and costs comparatively low. It is suitable for medium or small size converters.
