当弯曲板在造船过程中的成型操作中发生变形时，需要反复测量变形形状并与设计形状进行比较。由于存在大量不同尺寸和形状的大型曲面板，因此高效的测量和比较过程对于快速、准确地检查变形板的质量至关重要，从而提高整个制造过程的生产率。目前，变形板是使用传统模板来测量和检查的。这种做法不仅耗时，而且容易出现人为错误。因此，需要提出一种简化测量和比较过程的新方法。本文介绍了一种用于弯曲板测量和比较的有效算法。构建了全尺寸测量机及其控制软件，并实现了比较系统的算法。集成算法通过许多不同尺寸和形状的弯曲件进行了验证。
When a curved plate is subject to deformation during the forming operation in the shipbuilding process, the deformed shape is repeatedly measured and compared to the designed shape. Because there are a number of large curved plates of different sizes and shapes, efficient measuring and comparison processes are essential to examine the quality of deformed plates rapidly and accurately, and consequently to enhance productivity in the whole manufacturing process. Currently, deformed plates are measured and examined using traditional templates. This practice is not only time-consuming but prone to human errors. Therefore, a new approach to streamlining the measurement and comparison processes needs to be proposed. In this paper, an efficient algorithm for the measurement and comparison of curved plates is introduced. A full-scale measurement machine with its control software is constructed, and an algorithm for the comparison system is implemented. The integrated algorithm is verified with many curved pieces of different sizes and shapes.
