实现了在Android平台上快速图像匹配的增强现实。针对目前基于自然特征的增强现实效率低和智能手机的普遍性，提出ORB算法在Android平台上的实时注册方法。提取基准图像与视频帧中的特征点及描述子，使用汉明距离匹配，计算摄像机的位姿，将三维虚拟物体叠加到真实场景中，达到虚实结合的效果。在基准图像部分被遮挡及不同尺度角度的情况下，ORB在Android平台上跟踪定位准确度高并且速度可达到实时要求。

This paper implements rapid image matches on Android platform for augmented reality.Aiming at the low efficiency of augmented reality-based natural features and smart phones universality, the algorithm of ORB is proposed on the Android platform for real-time registration method.Reference picture and video frames extract feature points and descriptors,by matching Hamming distance,calculating the position and orientation of the camera, the three-dimensional virtual objects superimposed into the real scene for the actual situation with the results.In the case of the reference image partially is blocked and angles of different scales,ORB on Android can achieve real-time requirements in tracking accuracy and speed.
