| Abstract: | In three-coordinate measurement,measuring path optimization is a basis for automatic measurement of free-form.In this paper,several typical methods for measuring path planning are presented and analysed,and a cubic spline interpolation based on the polynomial method is developed.According to this method,a entity had been measured and the data been compared with which was acquired using the polynomial method.Validation test shows that this method can enhance the metrical precision and efficiency. |
