基于NURBS的报废汽车挡风玻璃边缘轮廓拟合方法研究

摘要

For the sake of disassembling windshield of ELV automatically, the fitting method for trajectory of cut⁃ting windshield is presented. The basic theory of NURBS is introduced, the feasibility of apply NURBS theory in⁃to fitting of edge profiles of windshield is researched. The process of fitting of windshield contour of ELV base on NURBS is presented. The properties of fitting curve, high fairness and similarity to real contour of wind⁃shield, are validated.%　　针对报废汽车挡风玻璃自动化拆卸的需要，对NURBS理论在报废汽车挡风玻璃边缘轮廓曲线拟合中应用的可行性进行了研究，并进行了验证。提出了利用NURBS理论进行挡风玻璃边缘轮廓曲线拟合的流程，通过实例验证了基于NURBS理论的边缘轮廓拟合曲线具有光顺性好、与实际曲线相接近的特点。
