%X Calculating methods of normal vector, principal curvatures and principal directions at each triangular mesh vertexes are researched. Types of vertexes on surface are analyzed. A method for mosaicing broken objects based on fractured faces matching is presented. Directed feature vectors and undirected feature vectors used in surface matching are consisted of directed footprints and undirected footprints respectively. Directed features similarity of pair of matching points is measured through mapping direction of matching points based on undirected features matching. Calculating for matching fractured face is completed. Based on fractured face matching, broken objects mosaicing are realized through mapping direction of pairs of matching points. Experimental results show that presented algorithm can mosaic broken objects reliably.
