中文摘要:

      基于标识点的增强现实系统中，计算机生成的虚拟物体需要正确地注册到相应的标识点上构成对现实环境的增强。针对增强现实三维注册过程中传统算法标识点匹配过程中误识率较高，匹配不够精确的不足，提出了将相对误差法进行改进实现增强现实中的三维注册，同时提出了将基于颜色直方图的图像匹配原理引入增强现实的三维注册过程中，通过实验验证与分析，改进后的匹配算法与传统算法相比减少了标识的误识率，提高了注册精度，已成功应用于增强现实系统的三维注册过程中。

英文摘要:

      In the system of augmented reality(AR) based on marker image,the virtual object generated by the computer needs to be registered to the corresponding point properly to enhance the reality.The insufficient of the traditional algorithm of the three-dimensional registration process in augmented reality is analyzed,a method to improve the registration in the augmented reality is put forward.Through experimental verification and analysis,this method reduces the error rate of the identification and improves the registration accuracy,which has been applied in the three-dimensional registration process successfully.
