Abstract:
An improved mechanism for calibrating a local positioning system through the use of passive or retro-reflective markers is described herein. A plurality of imaging targets with the passive or retro-reflective markers may be attached or affixed on a surface of an object. The local positioning system may then capture a first image of the imaging targets in a non-illuminated state and further capture a second image of the imaging targets in an illuminated state. A difference image between the first and second captured images may be computed and then segmented. The local positioning system may then identify the plurality of imaging targets based on the segmented difference image and position itself to extract information. The extracted information may then be used to help calibrate the local positioning system.

Claim (Index 1):
A method of controlling a mobile platform having a local positioning system, comprising:\n capturing a first image of a plurality of imaging targets ( 130 - 132 ) in a first state of illumination from a location, wherein the imaging targets are on a surface of an object; capturing, from the location, a second image of the plurality of imaging targets ( 130 - 132 ) in a second state of illumination; locating a center point of each of the plurality of imaging targets based on a difference image ( 300 ) generated using the captured first image and the captured second image; acquiring a distance reading based on a distance measurement from the center point of each of the plurality of imaging targets ( 130 - 132 ) and a local positioning system ( 120 ) of the mobile platform; and controlling movement of the mobile platform at least in part based upon the acquired distance reading.
