摘　　要：面向实物的逆向工程技术是近几年来研究和发展的热点,已广泛应用于产品设计、文物保护和零件修复等领域。报告了对模型的残缺表面数据进行曲面和实体重构的研究现状,以及结合正向和逆向建模软件进行实体模型重构的局限性。介绍了应用软件Geomagic Design Direct进行实体模型重构的优势以及对残缺表面数据实体模型重构的一般流程。提出了基于软件Geomagic Design Direct的特征识别与提取功能,对残缺表面数据进行实体重构的解决方案,并以某一零部件的残缺表面数据为例进行实体重构验证了该方案的可行性和便利性。Reverse engineering technology of real model is a hot research field in recent years,which was widely applied in product design,cultural relics protection and parts repairing. This paper researched the study status of surface and solid reconstruction of incomplete surface data,and the limitation of applying forward and reverse modeling software for solid model reconstruction. Introduced the advantages of applied Geomagic Design Direct for solid model reconstruction,and the general process of solid model reconstruction for incomplete surface data. The solution for the solid model reconstruction of incomplete surface data was proposed,based on the capability of identification and recognition of feature by Geomagic Design Direct,and an example of part＇s incomplete surface data was taken to validated the feasibility and convenience of the solution.
