摘要

介绍了形态学中开操作和闭操作在曲面去噪中的应用,在所设计的原始曲面上随机设置噪声,对含噪声的原始曲面型值点数据进行开操作和闭操作,减少或消除噪声。应用Unigraphics软件中的NURBS完成曲面重构,并对曲面重构的精度和效率进行了分析、验证。
The application of the open and close operation in morphology in the de-noising of surface was presented.The noises are filtered from the constructed original surface by using open and close operation,and then the surface is reconstructed by NURBS of Unigraphics.The precision and efficiency of the reconstruction were analyzed and validated.
