Correlating video-captured 3D foot model with foot loading during walking

The intensity of research to study the functioning of the human foot and the body-weight loading impact on its performance has increased considerably in the last five years. This type of research is particularly important for injured or deformed foot. Low-cost HD video cameras are becoming popular for capturing accurate three-dimensional (3D) model of the human body parts and they have shown to be useful for the study of the human foot during walking. A research was carried out to determine whether continuous capture of the 3D models of the foot during walking can assist in the understanding of the loading characteristics of the foot. This paper provides discussion on the methods used to correlate the video-captured 3D model of the foot and the force plate recording of the foot-loading during walking. The discussion covers the test methods and the results of the study. The studies show that the techniques developed produce precise correlation between foot loading and the video-captured 3D models and these data could be used for the mentioned applications.
