Abstract:
In this study, a 2-D hybrid markerless technique is proposed to estimate the lower limb joint kinematics
from data recorded using a video camcorder. The presented markerless methodology is defined as
hybrid because garments like high-cut underwear and ankle socks were used as “segmental markers”.
High-cut underwear contributed in defining the pelvis segment and ankle socks are used for the
definition of the foot segment. The method was applied to a video sequence acquired with a video
camcorder. The method was validated by using a stereophotogrammetric marker-based system.
Correlation and Root Mean Square Deviation (RMSD) of the joint kinematics estimates obtained with
the two techniques were found to be similar. The proposed hybrid technique can be considered as an
easy-to-configure and affordable alternative to marker-based photogrammetric systems for the
estimation of the lower limb joint kinematics.
