Research on Key Technologies of Mobile Augmented Reality System

介绍了移动增强现实系统技术原理,并对移动增强现实系统标识物检测识别、特征点描述、标识物注册、高效渲染等关键技术进行了研究。采用SURF算子对展板标识物的特征点进行检测与描述,以特征点为中心构建标识物的SURF特征点坐标系,通过矩阵变换实现标识物的跟踪注册,基于OpenGL ES 2.0技术对增强现实内容进行高效渲染。实验结果表明,基于以上关键技术的移动增强现实系统具备较好的鲁棒性、稳定性和实时性。

This paper introduces the technology principle of mobile augmented reality (MAR) system. The key technologies such as detection and recognition of mobile augmented reality system identifiers, description of feature points, registration of signatures and efficient rendering are studied. The system detects and describes the feature points through SURF and constructs coordinates of SURF feature points, and realizes the tracking registration of the marker by matrix transformation,and render the augmented reality content with the OpenGL ES 2.0 which has high performance. Experimental results show the robustness, stability and real-time of the MAR system.
