 摘  要
 随着计算机技术的迅速发展，特别是逆向工程技术在工业上已经得到了广泛的应用。为了解决手机外形设计周期长的困难，本文研究了手机外形的逆向工程造型方法，并对逆向工程进行系统的阐述。Imageware主要用来做逆向工程，是最著名的逆向工程软件,广泛应用于设计与制造领域。本文通过imageware软件详细介绍对手机外形进行逆向工程的步骤，对手机外壳点云进行分割，提取特征曲线，形成拟合曲面，对拟合曲面进行误差分析、调整，得到合适的曲面，最后进行曲面构建，进行误差分析。

Abstract
 Along with the rapid development of computer technology, especially the reverse engineering in the industry has been widely used. In order to solve the phone shape design cycle long difficulties, this paper studies the appearance of mobile phones in reverse engineering, modelling methods, and reverse engineering systems. Do Imageware mainly used in reverse engineering, is the most famous reverse engineering software, widely used in designing and manufacturing. Based on a detailed introduction imageware software for mobile appearance of reverse engineering, cell phone casing point cloud, extracting characteristic curve, the formation of surface fitting, surface fitting for error analysis, adjust the surface, suitable for construction, and finally, error analysis.
Key words:　 Reverse engineering    Imageware software   cell phone casing point cloud
