3D models feature point extraction is currently operating efficiency and reliability issues,a new algorithm for extracting model's feature points based on macro characteristics is proposed.In the foundation of traditional feature point extraction algorithm macro feature point detection is added,this can optimize the extraction of feature points.Experimental results show that using the feature point extraction algorithm can improve the accuracy and reliability,and has better results for the model which has lots of noises.
