摘要
A级曲面重构是车身外覆盖件设计的关键环节,针对传统方法重构复杂自由曲面效率低下、灵活性差、曲面质量不高的状况,提出一种基于NURBS面片的A级曲面重构方法,曲面调整灵活、直观,有效提高了A级曲面重构的效率和质量。
Class_A surface reconstruction is a key part in body exterior design. Because traditional method has some disadvantages like low efficiency, bad flexibility and low surface quality in complicated surface reconstruction, this paper presents a method of Class_A surface reconstruction from point clouds based on NURBS patch, which makes surface design more flexible and direct, improve the reconstruction efficiency and surface quality.
