Patent ID: 8494614

Claim:
A method of correlating a first coordinate system of a first tracking system and a second coordinate system of a second tracking system, comprising: determining a registration of the first coordinate system of the first tracking system and the second coordinate system of the second tracking system based on determining a first position with the first tracking system and determining a second position with the second tracking system; determining a vector displacement between the determined first position of the first tracking system and the determined second position of the second tracking system; transforming the determined first position with the first tracking system relative to the determined second position with the second tracking system; collecting a first set of position data with the first tracking system and a second set of position data with the second tracking system; determining a plurality of vectors, wherein one vector is determined between each synchronously related position data in the first set and the second set; interpolating position data collected with the first tracking system to register the first coordinate system to the second coordinate system of the second tracking system; and translating a determined third position of the first tracking system relative to a selected position of the second tracking system based on the determined vector displacement.
