【摘要】 提出了一种通过对转炉炉口火焰纹理特征的分析，判断氧气顶吹转炉吹炼终点的方法和检测识别系统技术方案．主要工作包括火焰图像的采集，图像的预处理，纹理特征的提取与选择及特征参数的分析比较；同时编制了应用程序．实验结果表明，该方案避免了复杂机理建模的困难，对转炉炉口的大小没有要求，在费用上相对较为节省，适合中小转炉使用．更多还原

【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.更多还原
