| 摘 要： | 提出一种自由曲面的非接触自动测量方法。测量系统由三坐标测量机、ＰＨ１０回转体和激光三角测头组成。ＰＨ１０回转体带动激光测头回转实现对空间任意自由曲面的测量。利用激光测头在工作距离之外无信号输出这一特点进行曲面边缘提取，基于边界曲线在空间内均匀划分扫描网格，采取仿形跟踪措施实现测头的跟踪。实验证明该系统能自动完整快速测量四边曲面，测量精度优于６０μｍ。

| Abstract: | Traditionally, contact measurement or simple non-contact measurement based on Coodinate Measuring Machine are used for the measurement of free-form surface with high accuracy. The defects of these methods are of lower efficiency and automation. On the basis of a thoroughgoing study of the above methods, a non-contact method for measuring free-form surface automatically is given, some key techniques are also described. |
