IMU and motion capture dataset for hip joint range-of-motion analysis

This dataset contains all experimental data from 16 subjects, with a total size of approximately 1.65 GB.The data content includes 4 folders:Merged dataset files (16 CSV files) where each subject has completed decoding, synchronization, and annotation;Original IMU data files (16 TXT files) and corresponding decoding program files (1 ipynb file) for each subject;16 CSV files of lower limb joint angles calculated based on optical motion capture system;Three dimensional kinematic data of lateral knee landmarks, including position, velocity, and acceleration information (16 CSV files).The dataset file integrates multi-sensor signals, joint angles, and action labels, making it easy to directly use for subsequent modeling and analysis. Each Px_dataset.csv file has a unified field, including timestamp, acceleration and angular velocity of 8 IMUs, quaternion and attitude angle, 6 angles of bilateral hip joints in 3 anatomical planes, and hip joint action labels. All files have passed integrity checks to ensure complete fields and continuous timestamps.
