Abstract:

To improve the reverse modeling efficiency of aeroengine pipelines, a region-growing segmentation algorithm for aeroengine pipeline point cloud data is proposed based on geometric attributes. The method maps respectively the geometric attribute value of measurement points to surface shape index paps of Koenderink, principal curvature coordinate system and gaussian sphere. Searches are performed for recognizing seed regions of point cloud data based on the characteristics of pipeline feature surfaces in the above geometric attribute mappings.
