摘要
为弥补场景图在增强现实装配应用中的不足,提出一种将层次着色Petri网与图灵机模型结合的方法,建立了增强现实装配环境系统模型。该模型借鉴图灵机的思想,以虚拟手的手势代号及位姿矩阵作为输入,输出具体操作事件更新场景图,记录系统的当前内部状态并根据用户输入给出下一步的操作响应。相对于单一的碰撞检测方法,该方法能更好地满足增强现实装配系统的动态实时响应等性能要求。开发建立了该模型的原型系统,并通过网络状态生成图分析验证了模型实时响应的能力。
To address the limitations of cene graph structure in augmented asssembly application,a method combined Hierarchy Colored Petri Net（HCPN） with turing machine model was proposed to establish the system model of augmented reality assembly environment.Based on turing machine,the gesture code and pose matrix of virtual hand were taken as input,outputs concrete processing events to update the scene graph.This model was able to record the current internal states of the system and the responses of next operations was given out according to users＇ inputs.Compared to the method of single collision detection,this model could satisfy the dynamic response requirements of real-time and concurrence of augmented reality assembly system.The prototype system was developed,and the ability of this model＇s real-time response was verified by analyzing occurrence gragh of the net.
