Patent ID: 7539595

Claim:
A method for determining coordinates of a workpiece ( 9 ) fastened to a movable structure, said movable structure having a reference object fastened thereto, comprising: measuring, using a first coordinate measuring device ( 3 ), first coordinates of said workpiece ( 9 ) in a first coordinate system; measuring, using said first coordinate measuring device ( 3 ), first coordinates of said reference object; measuring, using a second coordinate measuring device ( 5 ), second coordinates of said workpiece ( 9 ) in a second coordinate system; measuring, using said second coordinate measuring device ( 5 ), second coordinates of said reference object in said second coordinate system; and determining, using at least said first coordinates of said reference object and said second coordinates of said reference object, a set of coordinates for said workpiece ( 9 ) including coordinate values derived from said first coordinates of said workpiece ( 9 ) and said second coordinates of said workpiece ( 9 ).
