Efficient 3D design drawing visualization based on mobile augmented reality

Recently, in manufacturing, machinery, construction and shipbuilding industry, diversified researches of visualizing design drawings without difficulty utilizing augmented reality technology have been performed. In this paper, we propose efficient 3D design drawing visualization technique based on mobile augmented reality. Proposed technique first recognizes design drawing region, and only performs image tracking in its region. Through performance analysis, it could be seen that in technique being suggested in this paper, drawing recognition time was reduced by 4-33%, drawing matching recognition rate was increased by 5-15% and number of output frame per second was increased by 7-8 frames per second.
