基于线特征的增强现实注册算法

Augmented Reality Registration Algorithm Based on Line Features

提出了基于线特征的增强现实系统注册算法实现框架,将复杂的增强现实无标志注册问题分解为特征提取、特征匹配、三维重建、虚实融合4个可操作的具体阶段,针对每个阶段的关键技术给出了相应的解决方法,为进行无标志点增强现实系统注册算法的研究提供了理论模型;利用从运动中恢复结构的技术,通过跟踪图像序列的线特征,实现了基于线特征的增强现实注册算法,实验结果验证了该方法的有效性.

A system model of markerless registration with line feature is presented. The complicated registration problem is divided into four steps： feature extraction, matching, 3D reconstruction, and merge of virtual and real scenes. Key techniques and theories in each step are discussed. Using the technique of structure from motion, AR markerless registration is achieved by 3 D line tracking. Experimental results indicate that the proposed algorithm is effective.
