Computer vision localization based on pseudo-satellites

In following the ¿Signals of Opportunity¿ theme of the NAECON '09 Grand Challenge, we explore using computer-vision techniques for localization and orientation techniques to complement navigation via the pseudo-satellite technique proposed in. The proposed approach is not affected by the strength of the microwave, and is more accurate than the conventional time of arrival approaches. Methods based on limited and varying information of markers is discussed. Simple applications and experimentation based on augmenting a motorized wheelchair for vision applications is discussed.
