ABSTRACT:
A method is provided for correlating imprecise source data in a local coordinate system to a precise global eyepoint position for a global coordinate system within which the local coordinate system is located. The method includes the step of identifying key correlation points for the local coordinate system which has modeling inaccuracies. Global coordinates are also identified for each of the key correlation points. Another step is computing delta values for each of the key correlation points that represent the difference between key correlation points' local system coordinates and the global coordinate system's coordinate values for the key correlation points. An additional step is modifying the global eyepoint position based on delta values for selected key correlation points as the global eyepoint position moves in relation to the local coordinate system within the global coordinate system.
