This paper proposes a fracture surface matching algorithm based on integral invariants.Through comparing feature point's multi-scale volume integral invariants,it obtains initial matching point pairs and discard outliers.According to the similarity of surface patches based on compatibility constraint,it gets small and efficient matching point pairs.It calculates every 3D space transformation set which makes the normal vectors to the same one.A two level voting scheme based geometric hash is employed to find out optimal transformation.Experimental results show this algorithm can realize full and partial matching of fracture surface.
