Abstract

This paper made the edge reconstruction of the aircraft engine. First, collected rough point cloud data by using visual measuring equipment. Then, smoothed and filtered the point cloud data, took the reasonable simplification, finished pre-processing the point cloud data. Finally, non-uniform B-spline wavelet algorithm was used for acquisition feature point of blades´ edge, and took the digital model. The results proved that this method reduced modeling and machining time, and improved smoothness of the model.
