摘　　要：探讨了基于反求工程技术的管线三维反求建模策略,提出了基于Hough变换技术的管线平面、圆柱面特征的识别方法,以及管线的CSG模型构建技术,进而实现了对航空发动机管线的三维反求建模。经实践证明,该方法可以精确、有效地实现对航空发动机管线测量数据的反求建模。In this article the new methods based on reverse engineering technology have been presented which can be used for more efficient semiautomatic recon- struction of aeroengine pipelines from point clouds. The key technologies are investigated and developed, including extensions of Hough transform for the automatic detection of planes and cylinders, CSG fitting for model reconstruc- tion in the point clouds of aeroengine pipelines. The test- ing results show that the presented system is accurate and efficient in reverse modeling of aeroengine pipeline.
