Abstract

A method for acquiring gait parameters of an individual is disclosed. The method includes capturing calibration images from foot marker placed on feet or shoes of an individual while an individual is standing still, the calibration images are obtained from a camera worn by the individual, capturing subsequent time-varying images from the foot markers while the individual is walking, and comparing the calibration images to the subsequent time-varying images by a processing unit that is coupled to the camera to determine changes between the initial relative image size of the foot markers and the time-varying images of the foot markers as a function of time to analyze gait of the individual.
