3D Reconstruction Modeling Construction of Aeroengine Blades Based on Reverse Engineering
In order to accurately control the surface data of aeroengine blades,and meet practical application requirements of en-gine blades,this paper studies the 3D reconstruction model construction method for aeroengine blades based on reverse engineering.According to the principle of reverse engineering,collect the 3D data samples,and define the 3D data topological relationship with en-gine blades according to the error correction conditions,so as to analyze the neighborhood form of the 3D data samples and realize the 3D data neighborhood construction of aeroengine blades.Implement the 3D data point cloud splicing processing,follow the 3D fitting principle,extract the complete engine blade boundary,determine the range of the reconstructed quaternion according to the 3D recon-struction node configuration requirements,derive the specific reconstruction model expression,and complete the 3D reconstruction model of the aeroengine blades based on reverse engineering.Experimental results show that the coordinate error of the above model between the landmarks during modeling and the landmarks after the 3D reconstruction does not exceed 0.5 mm,which meets actual application requirements for precise construction of aeroengine blades.
