摘要

摘要: 反射线法目前在曲面品质分析领域广泛应用。针对现有反射线算法效率低下，反射线易失真和基准光源相关性太强等缺陷，通过优化距离函数模型，提出以入射光线与光源平面交点至基准光源线距离作为构建距离曲面的基础，确保了反射线法的准确性和基准光源无关性，根据等值线算法，优化了网格曲面上反射点分类追踪算法，并通过计算机编程实现了反射线的高效生成，通过若干分析实例验证了新算法的优越性，说明了该反射线优化算法可作为分析曲面品质的有效工具。

Abstract: Reflection line method is now widely applied to the field of surface interrogation. Considering the low efficiency of existing algorithm, the distortion of reflection lines and strong correlation of reference light source, this paper constructed the distance surface basing on the distance between the reference light line and the intersection point of each incident light and light source plane by optimizing the distance function model. Then the reflection points were worked out by classified tracing algorithm of grid surfaces based on the contour algorithm. The reflection lines were generated with high computational efficiency by computer programming. Finally, the advantages of the new algorithms were verified by several analysis cases of surface interrogation, and it also verified that the proposed optimization algorithm of reflection line is an effective tool for analyzing the surface quality.
