Claim One:
1. A method for calibrating image data from non-overlapping cameras, the method comprising: a processing unit tracking each of a plurality of individual objects distinguished within scenes of image data from each of plurality of non-overlapping cameras, wherein scenes of the images of different ones of the non-overlapping cameras are geographically remote and distinct from each other and do not overlap so that an object visible within any one scene cannot be visible within a scene from another camera at the same time; performing iterative across-camera image-matching to track the movements of objects distinguished from frame data of scenes of initial ones of the cameras to subsequent-in-time frame data of scenes of other, ending ones of the cameras, wherein the initial and ending cameras are defined by tracks of the objects moving from the initial camera scene to the ending camera scene; determining for pairings of the initial and ending cameras each of at least one path of motion of the tracked objects through each of the scenes of the initial and ending cameras, wherein the paths through the scenes are each defined by different respective scene entry and exit points; for each of the determined pairings of the initial and ending cameras, selecting a combination of one of the at least one paths through the initial camera scene and a path of one of the at least one paths through the ending camera scene as a path connection combination, in response to the selected combination having a highest total number of tracked movements of objects along the selected combination of the paths relative to a total number of tracked movements of objects along all other combinations of one of the at least one paths through the initial camera scene and one of the at least one paths of motion of the tracked objects through the ending camera scene; and for each of the determined pairings of the initial and ending cameras, determining a path connection of the initial camera scene to the ending camera scene as the scene exit point of the path connection combination path through the initial camera scene of the each pairing, and the scene entry point of the path connection combination path through the ending camera scene of the each pairing.
