Navigation using self-describing fiducials
First Claim
Patent Images
1. A self-describing fiducial comprising:
- a communication element that is configured to optically communicate navigation state estimation aiding information to one or more navigating objects in the vicinity of the self-describing fiducial for state estimation;
wherein the navigation-aiding information comprises a geographic position of the self-describing fiducial with respect to one or more coordinate systems.

Abstract
In one embodiment, a self-describing fiducial includes a communication element that optically communicates navigation-aiding information. The navigation-aiding information may include a position of the self-describing fiducial with respect to one or more coordinate systems and the communication element communicates the navigation-aiding information to one or more navigating objects in the vicinity of the self-describing fiducial.

17. A method for navigating comprising:
-
taking an image with a camera mounted on a navigating object; identifying a self-describing fiducial within the image; acquiring an optically communicated geographic position of the self-describing fiducial; and processing the optically communicated location to estimate at least one navigational state of the navigating object. - View Dependent Claims (18, 19, 20)
