1. A video augmented orientation sensor comprising:

  • a base sensor adapted to measure and provide orientation information;

    a processor coupled to said base sensor, and adapted to;

    receive a current set of orientation information from said base sensor;

    receive a first captured image from an image sensor at a known orientation to said base sensor;

    identify at least two reference image components in said first image;

    receive a subsequently captured image;

    compute displacement of said reference image components between said first and subsequent images;

    using said displacement, compute and update said current orientation information; and

    ,upon reception of a subsequent set of orientation information from said base sensor, utilizing data from said subsequent set to correct or replace said current orientation information.
