Data Matrix Codes (DMC) are established by these days in many areas of industrial manufacturing thanks to their concentration of information on small spaces. In today's usually order-related industry, where increased tracing requirements prevail, they offer further advantages over other identification systems. This underlines in an impressive way the necessity of a robust code reading system for detecting DMC on the components in factories. This paper provides a solution for the Data Matrix Codes recognition. Using the Mean Shift Algorithm, the main information of the DMC pattern are computed and based on these, a virtual identification pattern is constructed. Seeking and matching over the image, the Data Matrix Code is located. We concentrate on Data Matrix Codes in industrial environment, punched, milled, lasered or etched on different materials in arbitrary orientation.
