This method represents the virtual objects in Euclidean space instead of in affine space, which is consistent with the popular graphics rendering tools such as OpenGL and is more common in practice. A new classification based local and global tracking strategy to match features between the reference image and the currently frame directly is presented, which enables the augmented reality system working effectively even under large changes of viewing angles. A novel affine coordinate system definition method based on a collection of feature points is also proposed, which makes the tracking method effective even when not all the reference points are detected during the whole process, as long as there are at least four pairs of reference points correspondences.
该方法以仿射变换为桥梁来建立欧氏空间下的摄像机坐标系与世界坐标系之间的变换关系,它与OpenGL等当前流行的图形渲染工具一致,具有更强的通用性;采用基于分类的自然特征匹配策略,能够在视角和视点发生大幅度变化情况下依然正常工作;提出基于特征点集合的仿射坐标系定义方法,使增强现实系统在最小配置下只需4点追踪成功即可完成注册,比需要6点的透视投影方法具有更好的健壮性和精确性。
