针对高炉布料过程操作者无法直接观察炉内料流轨迹、料面形状等信息,利用光学原理,提出极坐标激光栅格测试技术,对料面进行标定测量.引入模式识别中的双目视觉技术进行轨迹检测,对布料轨迹图像采用边缘分析算子,优化算子阈值,获得布料过程中料流信息,重现料流轨迹的动态图像,为高炉布料模型提供数据支撑. In view of the fact that the operator of the blast furnace cloth process can not directly observe the flow track and the shape of the material surface in the furnace, a polar laser grating test technique is proposed by using the optical principle to calibrate the surface of the material. The binocular vision technology The edge detection operator is used to detect the trajectory of the cloth, and the operator threshold is optimized to obtain the stream information in the cloth course and reproduce the dynamic image of the stream path, which provides the data support for the blast furnace cloth model.
