Sistema para el análisis de movimiento en dos dimensiones Cinemed II

Abstract

This paper describes the development of the second phase of the human movement analysis system called CineMED. It is based on videogrammetry methods and image processing in order to record the human movement. We used a digital camcorder, which was located to four meters of the person, capturing its gait in the Sagittal Plane. Also, we developed a kinematic model of lower limbs; this model takes the position data of the bony landmarks and calculates the joint angle of the hip, knee and ankle, besides the pelvic tilt during gait. In the second phase we enhance the results of the system and modified the digitalization module in order to acquire the kinematics data in an automatic manner. The software uses the kinematics data of an optical arrange and kinetics data of a force platform and applies a dynamic inverse method in order to compute the net reaction joint force. Finally, we carry out experiments to measurement the performance of the system. © Springer-Verlag Berlin Heidelberg 2007.
