AI Technical Summary
Technical Problem
Existing automatic labeling technology lacks adaptive matching capability on curved instrument housings, resulting in problems such as label lifting or local gaps during installation.
Method used
By acquiring the contour point data of the workpiece to be mounted, a forward and reverse index sequence is established, the direction of contour point change is identified, the change interval is merged, the constraint source interval is expanded, a set of closed segments is generated, and the mounting path is adjusted to match the surface shape.
Benefits of technology
It achieves precise attachment to curved instrument housings, ensuring a tight fit between the label and the housing, avoiding lifting or gaps, and improving the adaptability and consistency of automatic labeling.

Abstract
本发明提供一种用于自动贴标的弧度匹配方法及系统，涉及数据处理技术领域，所述方法包括：将各轮廓点按照正向顺序和反向顺序建立索引序列，识别轮廓点的变化方向并将相同变化方向的轮廓点合并为变化区间，将相同变化方向的变化区间合并为区段，识别闭合区段沿贴附方向的偏移程度，得到区段形态偏移值，提取相邻闭合区段之间的边界轮廓点，将各闭合区段之间的边界连接关系进行串联组合，识别不同闭合区段之间的衔接一致程度，得到整体轮廓耦合值，根据区段形态偏移值和整体轮廓耦合值对预设贴附路径进行修正调整，得到目标贴附路径数据。本发明能够实现贴附路径对工件实际曲面轮廓的适配，使贴附路径能够随轮廓变化进行调整。
