二维平面内的增强现实虚实配准问题研究

Virtual-real registration research in 2D planar augmented reality application

增强现实是把计算机产生的虚拟物体或其它信息合成到用户看到的真实世界中的一种技术。实现虚拟信息与真实景象的正确匹配或有机结合是每个增强现实实用系统都必须完成的一项重要任务。文中在对二维平面内增强现实应用研究分析的基础上 ,重点讨论了图像分析技术在虚实配准问题中的应用 ,提出了一种基于数值背景表达的快速虚实配准策略 ,以提高虚实配准过程中场景特征点提取的精度和速度。

Augmented reality is the merging of synthetic sensory information into user's perception of a real environment. One of the most important tasks for every augmented reality application is to merge the virtual scene and real scene correctly and make it be an organic whole. Based on the analysis of 2D planar augmented reality application, the application of image analysis technology in virtual-real registration is investigated. A numerical background expression method is put forward to facilitate the feature point extraction in the virtual-real registration process. \;
