An orientation sensor utilizing an inexpensive but relatively slow base orientation sensor, augmented by capture of a video images, identifying reference objects or regions therein, and calculating displacement of those objects to derive supplementary orientation information. Recurrent base orientation sensor results are used to correct drift of the video based technique. Augmenting the slow but accurate base orientation sensor with the consecutive images derived orientation data, provides a fast and inexpensive orientation sensor. |
