风扇叶片的非接触测量和三维建模研究
摘要: 随着计算机技术的迅速发展,计算机三维造型技术特别是逆向工程技术在工业
上已经得到了广泛的应用。为了解决风扇叶片难以精确测量的问题,本文研究了风扇叶
片外形的逆向工程造型方法,并对逆向工程概念、方法进行系统的阐述。通过光学扫描
仪的非接触测量获取风扇叶片表面的云状数据,并利用Imageware和geomagic软件对测
量数据进行处理,且基于NURBS曲面重构理论进行叶片造型表面重构,最终实现了风扇的
曲面重构,产生风扇的三维模型及二维图。与传统的正向设计方法相比,该方法提高了
工作效率,缩短了新产品的开发周期。

Fan Blade non-contact measurement and 3D Modeling 
Abstract: With the rapid development puter technology, Three-dimensional
computer modeling technology, especially the reverse engineering technology in the industry,
has been widely used. Fan Blade difficult to solve the issue of accurate measurement, This
paper studies the shape of the fan blade reverse engineering modeling method, And reverse
engineering concepts, methods and systematic elaboration.  By optical scanners access to the
non-contact measurement of the fan blade surface cloud of data, with Imageware and
geomagic, the measurement data is processed and NURBS surface reconstruction based on
the theory blade shape surface reconstruction, The ultimate realization of a fan surface
reconstruction,  Being designed with the traditional method, The method improves the
working efficiency, Shorten the development cycle of new products.
Key words: Reverse Engineering;   Non-contact measurement;  Point Cloud; Modeling
