摘　　要：柱面轮廓的数字化测量及数据处理是其反求工程的关键技术,将直接影响曲面重构的精度。采用了接触式测量方式获取工件数据。这种测量方式配合测量软件可快速准确地测量出物体的基本几何形状,如面、圆、圆柱、圆锥、圆球。针对复杂曲面的数字化测量和数据处理,提出了建立形状不规则零件测量坐标系的新方法和最佳测量规划,对测量数据进行高精度的处理,得到了反求工程中曲面重构的"点云"数据。Digital measure and data processing are the key technology of cylinder outline in reverse engineering(RE),they will directly affect the precision of surface reconstruction.The key to measure the cylinder outline is to gain the surface data quickly and accurately,so we adopted the contact type.Matched with software,we can measure the object shape quickly and accurately,such as the circle,cylinder,cone, round ball.The paper presented the new method of abnormity part measuring coordinate,the best measuring layout and higher precision data processing for the processing of complex surface.The “point” data for surface reconstruction of RE were obtained.
