To meet the needs of fast blade surface inspection,investigates the technique for analysis of airfoil deviation by using optical scanning data.The principles of optimal scanning and the data collection process are described in detail.Then feature-point based pre-registration and the SVD-ICP algorithm are used to perform registration from the measured model to the theoretical CAD model.Further,statistical analysis of deviation is presented by doing deviation calculation of cross-section data obtained by UG/API functions.Meanwhile,considering that the tolerance requirements differ in different parts of a cross section,a contour parameterization based method for tolerance zone design is proposed,which can satisfy practical needs.Based on the above algorithms,programming tools such as VC+ +,UG/API and VTK are used to develop a software for deviation analysis of blade surfaces,and this has significant implications for achieving fast blade surface inspection.
