Comparison IMU vs Optotrak

This is a dataset of IMU and optical motion capture data recorded on 16 healthy subjects while performing a series of upper body movements and exercises. A detailed explanation of the setup and experimental protocol is provided within the folder. In short, the goal of this experiment was to assess the accuracy and precision of a series of IMU calibration protocols against a gold standard optical system.

本数据集为16名健康受试者完成一系列上肢动作与练习时采集的惯性测量单元（Inertial Measurement Unit, IMU）与光学动作捕捉数据。该数据集文件夹中提供了实验装置与实验流程的详细说明。简言之，本实验旨在以金标准光学运动捕捉系统为参照，评估一系列IMU标定方案的准确度与精密度。
