| 摘 要： | 采用计算机视觉的方法对水火弯板的线位移进行测量，旨在找出板材在水火弯曲成形加工中的变形规律，为实现水火弯板的机械化和自动化提供数字参考。然测量精度的高低直接决定着这些数据的可靠性，而在影响视觉测量精度的诸多因素中，标定块的尺寸精度是一个重要的内容。相对真值可通过损失函数的分析来认定。

| Abstract: | Computer Vision is takn as means to measure the linear transfiguration in line heating and provide correct data for quantitative analysis. The measurement precision is essential, which determines the reliability of the measurement results. The size precision of the calibrating board is one of the important factors which affects the measurement accuracy. The relative true value could be decided through the analysis of the loss function. |
