1. A computer implemented method for automatically determining field of view overlap among multiple cameras as a function of the temporal overlap of object tracks, the method comprising executing on a processing unit the steps of:

  • determining values of similarity for potential pairings of each of a plurality of object tracks of movements of objects over time through a field-of-view of a first camera with each of a plurality of object tracks of movements of objects over time through a field-of-view of a second camera;

    assigning into pairs each of the object tracks within the first camera field-of-view to ones each of the object tracks within the second camera field-of-view that each have a highest determined similarity value of the similarity values determined for their respective potential pairings; and

    determining that the assigned object track pairs correspond to overlapping portions of the fields-of-view of the first and second paired cameras if portions of each of the assigned object track pairs have a temporally overlapping period of time.
