（5）设备情况：人体下肢运动信息采集分别由HIKVISION网络摄像头与自制的人体姿态传感器实现；人体下肢运动分别在荷兰Tacx骑行台与跑步机上实现。

This dataset is developed for the analysis of relevant indicators associated with human lower limb movement.
(1) Data Content: Primarily includes raw data, research analysis data, and other files or content derived from the datasets of human lower limb movement information indicators, including joint angle, step length, stride length, foot swing speed, and range of motion (ROM).
(2) Collection Protocol:
Volunteer Selection: Volunteers are selected from postgraduate and undergraduate students.
Collection Process:
1) Volunteers arrive at the test site, read and sign the informed consent form;
2) Conduct tests on lower limb movement information indicators;
3) Save the test results.
(3) Collection Location: Biomedical Engineering Research Center, Chongqing University of Posts and Telecommunications.
(4) Collection Period: January 2021 to June 2022.
(5) Equipment Setup: Human lower limb movement information is collected using HIKVISION network cameras and self-made human posture sensors. The human lower limb movement tests are conducted on a Dutch Tacx cycling trainer and a treadmill, respectively.
