Designing a 3D human movement analysis system

Human movement is fast and complicated. Human movement analysis system is used in occupational biomechanics to have a better understanding of the kinematics of human movement. The purpose of the current research project is to create a low-cost portable human movement analysis system that can be used to investigate human movement for three-dimensional (3D) kinematics analysis using two cameras. This human movement analysis system performs image analysis with MATLAB. The design and development method has five major steps, which include (1) the design and calculation of XYZ coordinates, (2) the design and development of human movement analysis system, (3) the design and development of system calibration, (4) the determination of a 3D Cartesian system, and (5) the design and development of human movement tracking and recording systems. Findings indicate that the total costs of a human movement analysis system in the current are less than 1,500 USD. In addition, this human movement analysis system has many practical uses for outdoor research projects.
