摘要
提出了利用超声波检测探头实现自由曲面的路径受控仿形测量方法。针对数据压缩处理引起的各截面曲线上数据点数的不同,提出了一种蒙皮B样条曲面插值方法,该方法在保持插值精度的情况下,减少了曲面重构所需的控制顶点。应用表明,算法计算效率较高。
The paper present a method of profiling measurement of path controlled based on ultrasonic inspection. Aimed at dealing with the problem of sectional curves with the different measurement data points arising from the data reduction, a new approach for lofted B-spline surface interpolation to sectional curves was presented, which reduced the number of control points while maintaining precise interpolation. Example results demonstrate the proposed approach is efficient in computation.
