Mobile augmented reality system for Design Drawing visualization

This paper suggests 3D Model Visualization System of Design Drawing based on Mobile Augmented Reality which supports information needed in real environment, which is made with adding virtual 3D objects to the 2D drawing by applying technology of augmented reality. The proposed visual system makes those who don't have any specialized knowledge understand the drawing easily, because 3D model is augmented over the drawing through camera of smart phone was added without any marker. Recognition time of suggested 3D model visualization system is reduced roughly 4 to 33 % compared with the existing method by extracting and matching feature point only in ROI, and recognition rate shows improvement of 5 to 15% Performance testing on the Android phone of the proposed system shows display of video faster over 7 to 8 frame per second compared to the existing method.
