Device and method for self-alighning position reference system
First Claim
1. A positioning system for a moveable platform comprising:
- at least one active array comprised of at least one light emitting element for transmitting a binary encoded identification positioned at a known location;
at least one camera for acquiring an image of said at least one active array;
means for receiving said binary encoded identification from said image;
means for processing said image to determine the position of said active array with respect to said moveable platform; and
means for combining said received binary encoded identification and said determined position to calculate a position of said moveable platform.

Abstract
A positioning system for a moveable platform comprising at least one active array comprised of at least one light emitting element for transmitting a binary encoded identification, where the encoding may be spatial or temporal, positioned at a known location, at least one camera for acquiring an image of the at least one active array, component for receiving the binary encoded identification from the image, component for processing the image to determine the position of the active array with respect to the moveable platform, and component for combining the received binary encoded identification and the determined position to calculate a position of the moveable platform.

6. A method for determining a position of a moveable platform comprising the steps of:
-
providing a plurality of active arrays at fixed positions each active array comprising at least one light emitting element for transmitting a binary encoded identification;
affixing at least one camera to a moveable platform;
imaging at least one of said plurality of active arrays with said at least one camera to produce an image;
performing image processing on said image to receive said binary coded identification and to determine a position with respect to said moveable platform; and
combining said binary coded identification with said position of said active array to determine a location of said moveable platform.
