1. A method for registering a first sensor and a second sensor in a measurement system, the method comprising the steps of:

  • sensing with the first sensor a first set of measurements from a first plurality of objects;

    sensing with the second sensor a second set of measurements from a second plurality of objects;

    generating a likelihood function associating a data element from the first set of measurements with a data element from the second set of measurements;

    generating a systematic error function based at least in part on the likelihood function;

    minimizing the systematic error function; and

    ,assigning an object from the first plurality of objects to an object from the second plurality of objects, based at least in part on the minimized systematic error function.
