DM04 – The analyse of the various methods for location of Data Matrix codes in images


Keeping in mind the end goal to enhance the proficiency and viability of 2D standardized tag identification calculation under complex foundation, discovery calculation for Data Matrix 2D standardized tag in view of territorial highlights examination furthermore, finding technique for line Snake calculation is introduced in this paper. Right off the bat, the district which contains “Ltype” standardized tag fringe is chosen by breaking down the highlights of every area.

Also, the standardized identification fringe is situated by utilizing line Snake calculation, and the four vertices of the scanner tag are fitted. At long last, the standardized identification is redressed by utilizing transmission move. Examinations demonstrate that the identification calculation of 2D standardized tag has great execution, and it is superior to customary standardized identification recognition calculation. It has solid enemy of obstruction limit, and can fulfill the requirements of ongoing on mobile phone.


Information Matrix standardized identification is a sort of two-dimensional lattice. The size and measure of information in the standardized tag are commonly free. The base size of Data Matrix is littlest in the majority of the two-measurement standardized identifications. So it is especially appropriate for stamping of little things. In the meantime, it utilizes Reed-Solomon coding to include blunder amendment encoding. So the standardized tag picture can be recognized precisely if no less than 20 percent picture can be perused even through the most scanner tag picture is harmed.


Going for the highly contrasting 2D scanner tag under complex foundation, a sort of standardized tag location calculation joining the provincial element investigation with situating through the line Snake calculation is proposed in this paper. In this technique, the primary district of scanner tag with “L-type” edge will be chosen through territorial element examination. At that point the scanner tag area is fitted as per the “L-type” edge. The four edges of scanner tag can be situated precisely by line Snake calculation. At long last, the standardized identification is amended through projective change utilizing the four vertices. Trials demonstrate that the calculation can fragment the 2D standardized tag from complex foundation well. In the real standardized tag pictures caught by versatile camera, it has great location viable. It runs quick and expends less space. It can well meet the constant necessity on the portable terminal.
