摘　　要：The worldwide research status of head tracking is introduced and the works made in the research of the predictive algorithm and in the exploration of the rule of the head tracking are set forth. A time delay model for the telerobotic scout system is built. In respect of eliminating error caused by time delay and making reasonable prediction to the data stream, many methods are experimented in order to realize the aim of real time tracking. The application of extrapolation algorithm and auto recursive algorithm in the orientation tracking is described in detail. These two algorithms are realized in Matlab environment. Through analysis of the curves generated by using these two predictive algorithms, an appropriate method was applied in the telerobotic scout system. The effect is satisfying.介绍了头部跟踪技术的研究动态 ,阐述了对头部跟踪规律的探索以及在预测算法的设计上所做的工作 .针对遥操作控制系统 ,建立了具有时间延迟的系统模型 .在消除时间上的延迟所造成的误差以及对这些数据流进行合理的预测等方面 ,采用了多种解决方案 ,以达到实时跟踪的目的 .详细描述了外插法和自回归法两种预测算法在姿态跟踪中的应用 ,并对这两种算法用Matlab进行了软件实现 .通过对两种预测算法下头部跟踪曲线的分析 ,选择了适合的方法应用在该遥操作系统中 。
