A Shape Matching Method for Train Dust Collector Based on Geometrical Features

Sun Guodong;Yang Linjie;Mei Shuzheng;Zhao Daxing;Hubei University of Technology;  
Due to the problem of inaccurate positioning of the train dust collector,a shape matching method was proposed based on geometric features.Firstly,the contour points were sampled and initial location of critical points and mapping relations of point sets were determined based on polar radius and local curvature.Then taking centroid as a benchmark,dual descriptors with geometric features of angles and scales were generated and processed by standard quantification.Finally,the similarity of the descriptors was calculated with modified Manhattan distance.The experimental results show that the proposed shape matching method is harldy influenced by geometric transformation such as scale,rotation,and translation,which demonstrates its adaptability and robust.
