Abstract
The present disclosure relates to a method and apparatus for determining the misalignment between a device and a pedestrian, wherein the pedestrian can carry, hold, or use the device in different orientations in a constrained or unconstrained manner, and wherein the device includes an optical sensor or camera. The optical sensors have a corresponding frame for the optical sensors' axes. The misalignment between the device and the pedestrian means the misalignment between the frame of the optical sensor assembly or camera in the device and the frame of the pedestrian. The present method and apparatus can work whether in the presence or in the absence of absolute navigational information updates (such as, for example, Global Navigation Satellite System (GNSS) or WiFi positioning).
