摘要
基于照片影像的反求工程和三维立体重建是企业新产品开发的重要途径之一。这里对照片影像反求设计方法作了较深入的探讨。在此基础上,研制开发了基于照片影像的反求设计及三维仿真的CAD平台。该平台的设计是在AutoCAD平台上,应用VisualLisp程序设计语言开发出“透视图布局”、“点反求”和“立体三维重建”等程序,并用AutoCAD的菜单定制技术为平台定制新增命令和帮助文件。应用实例证明该平台系统能够快速准确、半自动化地完成以平面体为主而组合的产品照片的反求设计与三维仿真。
Reverse engineering and 3D surface reconstruction based on the photo image are one of important approach that the business enterprises develop new products. This paper propose a method of reverse design for photograph image , and develop a CAD platform with reverse design and 3D surface reconstruction. Development of the platform is applied Visual Lisp program design language to program such us ＂perspective layout＂, ＂point reverse ＂, ＂3D surface reconstruction＂ and so on, and the help files and the menu is custom- made for the CAD system . The experiments proof that Reverse engineering and 3D surface reconstruction for the products photograph which are made up mostly fiat solids can be completed quickly, accurately and semi - automatically by means of the platform.
