摘    要：利用保护渣熔化过程中颗粒数量不断减少,完全熔化后颗粒完全消失的特征,提出了一种基于辐射图像处理技术的保护渣熔化速度测量方法。该方法采用机器视觉和图像处理技术,实现了保护渣熔化速度在线测量,并利用机器视觉库OpenCV实现了保护渣辐射图像中的中值滤波、图像分割、边缘检测和颗粒统计等图像处理功能并开发了测试软件。现场应用表明,以保护渣颗粒为检测信息的熔化速度测试理论及技术是可行的,与传统检测方法相比,新方法能定量检测保护渣的熔化速度并能实现熔化过程可视化监控。

Abstract: Particle number of protection slag is decreased with melting time,and disappeared after it is completely melted.According to this change,a new measurement method for melting speed of protection slag based on image processing technique was proposed.In this method,machine vision and image processing were used,and realtime measurement of protection slag melting speed was realized.Measurement software was developed utilizing Microsoft OpenCV software development kits to achieve a series of protection slag image processing,such as median filtering,image segmentation,edge detection and particle statistics.Field application shows that principle and method of the measurement were feasible,and new method can quantitatively measure melting speed of protection slag and achieve visible monitoring of melting process.
