摘　　要：为了有效避免带钢振动引起的测量误差,提出了一种基于改进的激光三角测量法的动态板形图像处理方法。该方法从钢板矫直的实际应用出发,利用数字图像处理技术完成了板形图像获取、板形图像特征曲线提取以及板形延伸率计算,较好地消除了由于振动带来的延伸率测量误差,延伸率计算结果满足工厂实际应用要求。In order to avoid errors in measurement caused by the strip steel vibration, this paper ward a dynamic flatness image processing method based on improved laser triangular detection puts formethod. From the practical application of strip steel straightening, the digital image processing technology is used to complete the flatness image capture, image feature curve extraction and calculation of flatness elongation. Finally, the method eliminates the errors in elongation measurement caused by the vibration; and the results of the calculation of elongation rate can satisfy the actual application in factories.
