XSENS Inertial Sensor Dataset

This dataset contains time series data of human joint angles collected using MoJoXlab sensor systems during various activities such as walking, jumping, squatting, and leg exercises. The dataset includes data for basic activities such as walking, sitting and relaxing, standing, lying down (supine position), jumping, and squatting. Additionally, it includes data for seated active and assisted knee extension/flexion and heel slide exercises. The data were collected at a sampling frequency of 50 Hz and exported as CSV files from both Xsens (https://www.xsens.com/) and NGIMU (https://x-io.co.uk/ngimu/) software. The joint angles were calculated using MoJoXlab software, which utilizes quaternion values to estimate the orientation of the sensors. The dataset consists of time series data collected from 15 participants using two sensor systems, Xsens and NGIMU, during various lower limb movements. The data were collected at a sampling frequency of 50 Hz and exported as CSV files. The dataset includes quaternion values for orientation, specifically for the left thigh (LT), right thigh (RT), left shank (LS), right shank (RS), left foot (LF), right foot (RF), and pelvis. The sensor positions are recommended by Xsens lower limb protocol. The column headers indicate the orientation (i.e., W, X, Y, Z and q0, q1, q2, q3), and P01_LT denotes participant 1 data for the left thigh sensor position. The dataset is useful for researchers and practitioners interested in studying human movement and developing algorithms for joint angle estimation. The data can be used to compare and validate different sensor systems and algorithms for estimating joint angles and develop and test new algorithms. The data can be downloaded and used for non-commercial research purposes with proper attribution to the authors and the data source.本数据集包含采用MoJoXlab传感器系统采集的人体关节角度时序数据，采集场景涵盖行走、跳跃、深蹲及腿部训练等多种活动。本数据集涵盖行走、静坐放松、站立、仰卧躺卧、跳跃及深蹲等基础活动的相关数据，此外还包含坐姿主动与辅助式膝关节屈伸、足跟滑移训练的相关数据。本次数据采集采样频率为50 Hz，可通过Xsens（https://www.xsens.com/）与NGIMU（https://x-io.co.uk/ngimu/）两款软件导出为CSV格式文件。关节角度数据通过MoJoXlab软件计算得到，该软件借助四元数（quaternion）值估算传感器的姿态。本数据集包含15名受试者在多种下肢运动过程中，通过Xsens与NGIMU两套传感器系统采集得到的时序数据，其采样频率同样为50 Hz，导出格式亦为CSV文件。本数据集包含姿态估计所需的四元数值，具体涵盖左侧大腿（LT）、右侧大腿（RT）、左侧小腿（LS）、右侧小腿（RS）、左侧足部（LF）、右侧足部（RF）及骨盆部位的四元数数据。传感器布局遵循Xsens下肢运动采集协议推荐的位置方案。数据列标题用于标识姿态分量（即W、X、Y、Z与q0、q1、q2、q3），其中P01_LT代表1号受试者左侧大腿传感器的采集数据。本数据集可供致力于人体运动研究、关节角度估计算法开发的科研人员与行业从业者使用，可用于对比、验证不同传感器系统与关节角度估计算法，亦可用于开发及测试新型算法。使用者可下载该数据集用于非商业性研究，但需注明原作者与数据集来源。
