在本研究中,使用光学运动捕捉系统 (Vicon) 评估 3D EMA(电磁关节记录)系统 Carstens AG500 的测量精度。定制的容器固定了 EMA 传感器和光学标记的位置,并记录了容器在 EMA 测量场内的一系列移动。结果表明,(a) 静态位置测量的非常小的误差并不能反映系统在动态测量中的行为,以及 (b) 在动态测量中,误差的大小在三个空间维度上变化很大。
In this study the measurement accuracy of the 3D EMA (Electromagnetic Articulograhy) system Carstens AG500 was evaluated using an optical motion capture system (Vicon). A custom-built container fixed the positions of the EMA sensors and the optical markers and a series of movements of the container within the EMA measurement field was recorded. The results show that (a) the very small error of static position measurements does not reflect the behaviour of the system in dynamic measurements and (b) that in dynamic measurements the magnitude of the error varies substantially across the three spatial dimensions.
