Measurement of a Walker’s Movement Parameters by a Monocular Camera

Abstract

This article elaborates on the theory of monocular measurement for a walker and uses experiments to validate this approach. This new monocular approach for measuring the movement parameters of a walker allows for the 3-D pose and position of the walker to be obtained using at least two endpoints on the target, the walker’s vertex and heel, and then other point’s position on the walker can be calculated. If the walker’s stature is not known, there is a coefficient of proportionality between the measured result and the true result. When the walker’s stature is known, the movement parameters of the walker can be measured in this way by a monocular camera, which can be used to study a person’s movement or to monitor person’s action in public places by monitor video.
