Abstract
A method for analyzing the stride of a walking pedestrian. It includes steps of: (a) acquiring, during a recording period, measurements of a motion of a lower limb of the pedestrian, (b) determining each stride made by the pedestrian, (c) dividing the recording period into recording sub-periods, (d) estimating a characteristic quantity of the stride for several detected strides, (e) selecting at least one characteristic stride quantity in a predetermined range of percentiles within a set formed by the estimated characteristic stride quantities, ordered by increasing values and occurring during a recording sub-period, (f) repeating step (e) for several recording sub-periods. The invention also concerns an equipment for analyzing the stride of a walking pedestrian, and a computer program product.
