基于几何矩阵的增强虚拟现实

增强虚拟现实是组合真实场景和虚拟场景,以达到丰富真实场景的目的.针对摄像机相对景深做较小运动时所获得的视频,提出了一种基于几何矩阵的增强虚拟现实方法.摄像机在这种运动情况下,可以用一个几何矩阵来描述两帧之间的关系,这样就大大简化真实场景和虚拟场景的组合.同时,由于虚拟场景来自二维图像,因此,非常容易对准虚拟物体在视频中的位置.理论和真实视频实验表明,本文提出的增强虚拟现实方法具有计算量小和真实性强等优点.

Augmented Reality Based on Geometry Matrix

Augmented Reality(AR) aims at merging the real scene and the virtual scene in order to enrich a real environment with virtual information.We address an augmented reality method that operates in environments that the translation of the camera is very small compared with the distant to the 3-D scene.This is a special case of the general problem,which significantly simplifies merging the real and the virtual,because a geometry matrix can describe the image motion between two frames of a video sequence.At the same time,the virtual can be obtained from images,so the alignment of the real and virtual coordinate methods is rather simple.The theory and experiments with real video sequence show that the proposed AR method is very simple and efficient.
