| 中文摘要 |
| 高炉炉喉煤气流分布是表征高炉生产状况的重要因素且无法直接检测; 本文提出一种基于炉顶摄像检测 的高炉炉喉煤气流形态三维模型重建方法. 首先建立检测系统的硬件结构, 其次对煤气流形态图像预处理后, 采用 边缘检测算法提取图像特征, 并提出基于方向链码的边缘跟踪算法, 计算煤气流形态的图像坐标; 最后结合摄像机 内部参数并利用坐标系三维变化关系以及坐标映射关系, 计算煤气流形态在三维空间的坐标, 从而重建煤气流形态 的三维模型. 通过仿真对比高炉布料后煤气流形态发展的4个阶段的三维模型变化, 估计气流形态的变化, 从而估 计高炉内部的煤气流分布状况, 对指导高炉布料操作以及高炉稳顺运行奠定了基础. |
| 英文摘要 |
| Because of the importance of the gas flow distribution in testing the production status and the undetectable nature of it, we propose a 3D model reconstruction method based on the top camera for simulating the gas flow distribution in the blast furnace throat. First, we build the hardware architecture of the detection system. Next, the edge detection algorithm is applied to extract the feature points after preprocessing the generated image. The shape of gas flow is drawn by the edge detection algorithm based on the director chain code. Then, combining the camera internal parameters, we obtained the coordinates for the gas flow in 3D model by using the relations of coordinate 3D transform and coordinate mapping. The 3D model for the gas flow distribution is built eventually. The change of the gas flow distribution after the blast furnace burdening can be inferred in simulation by comparing the variations of 3D models in four development stages of the gas flow distribution, resulting in the internal gas flow distribution of the blast furnace. This distribution will be used as the basis for guiding the operation of furnace burdening as well as making the blast furnace to run steadily. |
