摘要:
针对整个模型统一尺度规划和曲面间的衔接处理困难问题，提出“曲面模型-三角网格模型-截面线-点集-测点集”的规划策略，实现基于曲率特性的自适应测点规划。通过将数字化设计模型转换成统一粒度的密集三角网格模型，实现复杂型面的一致性描述；进而利用三角网格的拓扑信息，提取截面线；在截面线曲率估算的基础上，通过均分曲线质量进行测量点的自适应规划。结果表明,该研究能以较少的测点反映加工误差。
Abstract:
For the problem of uniform scale planning and convergence processing among multiple surfaces, a planning strategy of “curved surface model-triangular mesh model-section line-point set-measuring point set” was proposed to implement adaptive measure point planning based on curvature characteristics. The digital design model was transformed into a uniform granular dense triangular mesh model to achieve a consistent description of the complex surface. The section line was extracted by using the topological information of the triangular mesh. Based on the estimation of the curvature of the section lines, the adaptive measure point planning was performed with an equal division of the curves’ mass. The results of the simulation show that the method can reflect the machining errors with fewer measuring points.
