Abstract: Facing the questions including hierarchical clustering method and point cloud
sampling of the reverse engineering, the classification definitions are conducted and the
characteristics of hierarchical clustering method are studied. The key technology including the
surface variation and BSP construction are studied, and then the flowchart of algorithm realization
are constructed. The blade of hydraulic turbine belonged to a certain Factory is carried on
sampling and reverse modeling using this algorithm and Geomagic software. The feasibility of the
algorithm is verified by this example.

Key words: reverse engineering, hierarchical clustering method, point cloud sampling;
