For effectively reducing the amount of computation during the matching process,a method for two-dimensional fragments matching based on feature points is presented.The main idea of this method was effectively select the feature points by calculating the curvature after extract and de-noising the contour curve of the fragment.The ratio between arch length and chord length of the feature segment were used as a key to contour matching.Experimental result shows that this method improves computing efficiency and success rate of the matching.
