BRAVO M., D.A.; RENGIFO R., C.F. y AGREDO R., W.. Comparison of two Motion Capture Systems by means of joint Trajectories of human gait. Rev. mex. ing. bioméd [online]. 2016, vol.37, n.2, pp.149-160. ISSN 2395-9126. https://doi.org/10.17488/rmib.37.2.2.
Currently, the most common methods for proper capture of human movement in three dimensions require a laboratory environment and setting markers, accessories or sensors to the body segments. However, the high cost of equipment is a limiting factor in diverse environments. Motion capture systems such as Microsoft KinectTM present an alternative approach to motion capture technology.
In this paper, two motion capture systems are compared by means of joint trajectories and anthropometric Currently, the most common methods for proper capture of human movement in three dimension measurements of a person in a normal gait cycle. The first is accurate trading system that uses markers (ViconTM), and the second is Microsoft KinectTM camera. Both systems were evaluated in order to compare the geometric difference and the RMS error between the joint trajectories for Kinct, although this system is inexpressive and easy to use and install, cannot be used for precise kinematic analysis of human walking.
