| Summary: | The high cost of commercially available motion analyzer systems results in only a few
hospitals, health agencies, and rehabilitation centers in Indonesia are able to afford the system,
even though it is very useful for obtaining quantitative data on patient’s gait. The Biomechanics
Research Team at ITB has developed gait motion capture systems, starting with a simple single
home-video camera based for 2D analysis, and later using two cameras for 3D gait motion
capture. However, the earlier 3D Motion Capture System developed only able to record gait
motion of one leg, and employed a mirroring system to obtain motion of the other leg. Hence,
it is necessary to develop the 3D Motion Capture System further to enable motion capture of
bipedal motion.
In this study, a system that could capture and analyze the 3D gait of the bipedal motion
was developed. The system utilizes 4 action cameras and designed to enable capture of motion
and process the acquired images to enable kinematic and kinetics analysis to obtain gait
parameters. Calibration of the cameras are based on a checkerboard method, modified for the
system. The use of action cameras enabled data retrieval because it has a high frequency of
image retrieval. In addition, the use of action cameras results in a more affordable, portable, and
more shock-resistant system.
Data and resulting parameters obtained from the developed system are in agreement to
those found in the literature. Therefore, it may be concluded that the developed system could
be used for further gait analysis. Furthermore, the hardware developed could be used to analyse
other types of motion, not only gait.
