摘要

介绍了热轧带钢激光测形仪的图像处理系统。在生产过程中，由于带钢温度波动引起的图像背景灰度变化，对在线稳定的形状测量产生了不利影响。为此，提出了一种寻找自适应阈值的图像分割方法。根据自适应原理，借助于对区域图像直方图的在线分析，得到自适应阈值。

The adaptive threshold for image segmentation in shape metering of hot-rolling strip steel

An image processing system in laser shape-meter for hot-rolling strip steel is introduced. During production, a grey's variation of image background caused by the strip's temperature fluctuation has an adverse effect on the steady shape measurement online. For this reason, a method to seek an adaptive threshold for image segmentation is presented. According to the adaptive principle, with the help of the online analysis on histogram of the regional images, the adaptive threshold is obtained.
