摘要
针对基于人工标志的增强现实技术,提出了通过标志识别、顶点提取、三维注册和相机融合这4个步骤来实现的方案。重点研究了三维注册,采用针孔模型分析了标志顶点的图像二维坐标与三维坐标的关系,提出了通过多元线形方程组来求解三维坐标的算法。介绍了相机融合的过程及原理,验证了整个方案的可行性。
A method to realize augmented reality based on artificial marks is presented, including four steps: mark recognition, vertex abstraction, 3D-register and camera synthesis. The relationship of 2D-coordnates and 3D-coordnates of the vertexes is particularly analyzed. Propose an algorithm to calculate the 3D-coordnates by building a group of equations. Introduce the theory on camera-synthesis. Prove the feasibility of the method.
