To resolve the problem of the distortion of the 2-D barcode on the cylindrical surface,surface distortion model is setted up to correct the barcodes based on the automatic reading system of the two-dimensional barcode in the surface of tools.Moreover,considering some barcodes cannot display in one image,the missing barcode image based on image mosaic is recovered.First,the overlapped areas with related phase as the range of the feature collecting is estimated.Second,the SIFT points of related areas are collectted and the SIFT features with the algorithm of approximate nearest neighbor are matched.Third,the original images are revovered by using the step-in-step-out method.The experiments show that the algorithm improves the efficiency of the 2-D barcode reading.
