基于改进DenseNet网络的转炉吹炼时期识别

Recognition of Converter Blowing Periods Based on Improved DenseNet Network


摘要(Abstract):

针对炼钢生产中采用人工经验判断转炉吹炼时期准确率较低的问题,利用某钢厂转炉炉口火焰图像数据,提出一种基于深度学习的改进DenseNet网络转炉吹炼时期识别算法;该算法以DenseNet-121网络结构为基础进行裁剪,同时在分类层引入Center损失函数,并在100次模型训练中选取精度较高、拟合性较好的一次进行测试。结果表明:该算法通过特征复用,保证了分类精度,裁剪后的网络结构能够提升运算速度;在分类层引入Center损失函数能够改进相邻转炉吹炼时期分类模糊的情况,缩短了平均识别时间,分类的平均精度提高至91.75%。
