摘　　要：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 the process of blast furnace bell-less top charging,it is difficult for operators to directly observe the burden surface profile and burden trajectory.Based on the principle of optics,a polar coordinate laser grid measurement technology is proposed to measure the burden surface and burden trajectory.Dual CCD stereoscopic vision calibration with high precision is introduced to create the detailed computer images of the burden trajectory with a boundary operator,acquire information about the burden trajectory in charging,and reconstruct the process of blast furnace bell-less top charging.
