摘　　要： 提出了一种基于磁跟踪装置的自适应区域基准的三维注册算法并应用于增强现实车间布局中.该算法的基本思路是把磁跟踪发射器的半球空间划分为N个区域,每个区域都有相应的基准,当磁接受器到达每个区域时,自动地利用该区域的基准来注册定位.为验证所提出的算法,开发了一种网络环境下支持多用户协同设计的车间布局原型系统.系统运行及误差分析结果表明,此方法相对于直接使用跟踪装置的注册算法而言,精度及鲁棒性均有所提高,能较好的满足大环境下车间布局的精度和广度的要求. This paper proposes a adaptive region＇s three dimensional registration algorithm based on magnetic tracking device and uses this algorithm in workshop layout for augmented reality.The algorithm＇s main idea is to divide hemisphere space of the magnetic transmitter into N regions,each region has a corresponding benchmark,when the magnetic receiver reaches each region,the region＇s benchmark will automatically calculate the space coordinate position.To verify the algorithm,we developed a workshop layout prototype system which supports multi-user collaborative design in network environment.The system operation and error analysis show that the accuracy and robustness are improved and better meet to the accuracy and scope requirements of workshop layout in the larger environment by using this method than the registration algorithm which directly use of tracking devices.
