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.
Claims20
A self-describing fiducial comprising:
- a communication element that optically communicates navigation-aiding information;
- wherein the navigation-aiding information comprises a position of the self-describing fiducial with respect to one or more coordinate systems;
- and
- wherein the communication element communicates the navigation-aiding information to one or more navigating objects in the vicinity of the self-describing fiducial.
A system of self-describing fiducials comprising a plurality of self-describing fiducials, each self-describing fiducial optically communicating its location and position covariance information related to its location.
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 location of the self-describing fiducial;
- and
- processing the optically communicated location to calculate at least one navigational parameter of the navigating object.
