浇包出液口液柱图像特征参数构建方法研究

Research on the Construction Method of Characteristic Parameters of the Liquid Column from the Ladle Outlet

视觉浇注系统浇包出液口处图像经处理后提取的特征可以为后续浇口杯钢水液位识别和浇包塞杆启动控制提供判断依据。本文对比了单摄像头和垂直双摄像头两种方式获取的图像利用全局阈值分割和形态学算法去噪等预处理后构建出特征参数的情况,通过对比分析双摄像头方式构造的参数可以更好的为液位识别提供依据。

The molten steel volume of ladle is an important parameter for auto-pouring sys- tem based on machine vision. It is the fundamental of judging the level of sprue cup and the stopper rod start-stop time. By comparing the images obtained by single camera and binocu- lar camera, the global threshold image segment algorithm and the morphological image de- noising algorithm are applied to creat the characteristic parameters. Simulation results show that it is a more optimal way of judging sprue cup leve by binocular camera image.
