增强现实环境下的CPS虚拟装配系统研究与实现

基于双目视觉原理,利用Unity3D游戏引擎开发了一种增强现实环境下的信息物理融合(cyber-physical systems, CPS)虚拟装配系统。通过研究快速定位算法识别特征标记点建立虚拟模型与实物装配单元的配准关系,融合虚拟模型投影图像与实物装配体图像实现虚拟装配仿真,实时输出在视频眼镜结构中显示。经过试验验证,该系统满足CPS实时性、稳定性以及信息世界与物理世界融合的要求。

Research and implementation of virtual assemble system based on CPS under environment of augmented reality

Based on the principle of binocular vision, a virtual assembly system of cyber-physical systems (CPS) in augmented reality environment was developed by using Unity3D game engine. The registration relationship between virtual model and real assembly unit was established by studying the fast location algorithm through identifying the feature marker points. The virtual assembly simulation was realized by fusing the projection image of virtual model and the real assembly image, and the real-time output was displayed by the video glasses. The experimental results show that the system meets the requirements of real-time CPS, stability and integration of information world and physical world.
