运动捕获技术很少基于取向测量，这主要有两个原因：（1）光学运动捕获系统被设计用于跟踪对象位置而不是它们的取向（其可以从若干跟踪器推导出），（2）已知的动画技术，如逆运动学或几何算法，不断地需要位置目标，但仅偶尔需要取向输入。我们提出了一个完整的人体运动捕捉技术的基础上，基本上是方向测量。位置测量仅用于恢复表演者的全局位置。该方法允许快速跟踪用于交互式应用的人类手势以及高速率记录。几个动作捕捉优化，包括多关节技术，提高姿态的真实感。这项工作非常适合基于磁的系统，它更多地依赖于方向配准（在我们的环境中），而不是需要困难的系统校准的位置测量。
Motion-capture techniques are rarely based on orientation measurements for two main reasons: (1) optical motion-capture systems are designed for tracking object position rather than their orientation (which can be deduced from several trackers), (2) known animation techniques, like inverse kinematics or geometric algorithms, require position targets constantly, but orientation inputs only occasionally. We propose a complete human motion-capture technique based essentially on orientation measurements. The position measurement is used only for recovering the global position of the performer. This method allows fast tracking of human gestures for interactive applications as well as high rate recording. Several motion-capture optimizations, including the multijoint technique, improve the posture realism. This work is well suited for magnetic-based systems that rely more on orientation registration (in our environment) than position measurements that necessitate difficult system calibration.
