Barcodes have been wildly used in commercial retail and e-commerce field with the wide application of smart phones. In order to expand the direct part marking applications in industrial filed, the smart phone recognition characteristics of the laser marking barcodes on aluminum alloy surface were investigated by theoretical analysis and experimental verification. Due to different processing arts, the laser marking area may be in white, grey and black contrast colors. The conventional white barcodes recognition problem can be solved by the combination of complementary laser scanning and mirroring symmetry recognition condition, which has application value for the design of barcode recognition algorithm on smart phones and makes the high efficiency laser marking possible.

Abstract: Barcodes have been wildly used in commercial retail and e-commerce field with the wide application of smart phones. In order to expand the direct part marking applications in industrial filed, the smart phone recognition characteristics of the laser marking barcodes on aluminum alloy surface were investigated by theoretical analysis and experimental verification. Due to different processing arts, the laser marking area may be in white, grey and black contrast colors. The conventional white barcodes recognition problem can be solved by the combination of complementary laser scanning and mirroring symmetry recognition condition, which has application value for the design of barcode recognition algorithm on smart phones and makes the high efficiency laser marking possible.
