摘要
文中设计了一款适用于智能手机的混合现实盒子,用于书画临摹训练。它通过一块半透半反镜将手机屏幕上的立体视差图像反射到观察者眼中,同时借助手机后置摄像头捕捉周围环境,借助特征点匹配方法监测手机位置的变化,进而改变所显示的虚拟立体景物的位置,使之与周围真实环境的空间关系维持不变。实验表明,文中提出的基于特征点匹配的方法可以较好地解决MR中的空间对准难题。
A mixed reality box for smartphones is designed for training in calligraphy and painting. It reflects the stereo disparity images on the screen of the phone into the viewer’s eye through a half-transmitting-half-reflecting mirror. At the same time,the mobile phone’s rear camera captures the surrounding environment by means of rear camera of the phone,and monitors the change of the position by means of the feature point matching method. Then the position of the displayed virtual three-dimensional scene is changed so that its spatial relationship with the surrounding real environment remains unchanged. Experiments show that the proposed method based on feature point matching can solve the problem of spatial alignment in MR.
