摘要
介绍了钢坯在线测宽测厚系统的基本原理和系统组成。同传统的接触式测量相比,本系统利用红外热成像,通过计算和寻找梯度最大值进行钢坯边缘检测,根据梯度对边缘进行亚像素细分,对钢坯宽度和左右厚度尺寸进行实时测量。提出了非接触式钢坯尺寸测量中一种新的边缘检测方法,并从理论和生产实践上证明了该方法的可行性和正确性。
The basic theory and elements of the blooming melt of TSICO steel billet on-line measurement system is presented. The on-line non-contact measurement system adopts the infrared imaging technology. The program detects the steel billet's edge by computing the grads and searching the maximum grads, then subdivides the edge according to the grads. A new image processing technology is particularly presented, which is applied to this non-contact measurement system. With the mathematic analysis and test result, the new image processing technology is demonstrated to be practical and robust.
