摘要： 为解决移动设备多用户、大数据量目标的识别和跟踪问题，提出一种基于改进二维码的新型移动增强现实系统。通过C/S框架保证模型的更新，在客户端分离出识别和渲染过程，分析基于快速响应矩阵码的跟踪注册方法，针对其存在的跟踪范围小、跟踪不稳定的问题给出解决方案，从而完善系统。实验结果表明，与基于常规标志点和利用自然特征的方法相比，该系统方便实用、便于推广，且条码容易被手机使用，能识别出更多的信息。

Abstract: In this paper, a novel Mobile Augmented Reality(MAR) system based on improved two-dimensional code is presented, which uses C/S framework to keep the update of model. It isolates the identification and rendering process in the client, and analyses the existing tracing registration method of Quick Response Code(QRcode). According to the existing problem of it, such as small tracking range, unstable tracking, this paper gives the solution. Experimental results show that compared with the system using Artoolkit marker or nature feature, this system is flexible, efficient, and cell phone barcode is easy to deal with that can obtain more information.

Key words: Augmented Reality(AR), target tracking, Quick Response Code(QRcode), location symbol
