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。数据集涵盖行走、坐姿放松、站立、仰卧躺卧、跳跃及深蹲等基础活动的相关数据，同时收录主动坐姿膝关节屈伸、辅助坐姿膝关节屈伸以及足跟滑动训练的采集数据。本次数据采集的采样频率为50Hz，通过Xsens（https://www.xsens.com/）与NGIMU（https://x-io.co.uk/ngimu/）两款软件导出为CSV（逗号分隔值）文件；关节角度通过MoJoXlab软件计算得到，该软件利用四元数（quaternion）值估算传感器的姿态。本数据集同时收录15名受试者使用Xsens与NGIMU两套传感器系统完成各项下肢运动时采集的时序数据，采样频率为50Hz，导出格式为CSV文件。数据集包含各部位姿态的四元数值，具体覆盖左侧大腿（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，传感器布局遵循Xsens下肢传感器协议推荐的方案。列标题包含姿态相关参数（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位置的采集数据。本数据集面向致力于研究人体运动、开发关节角度估计算法的科研人员与从业者，可用于对比、验证不同传感器系统与关节角度估计算法，同时可用于开发及测试新型算法。本数据集可用于非商业性研究用途，但需正确标注作者及数据源。
