1. A method for tracking an object-of-interest over a global map formed as a composite of a plurality of camera-specific regions including a first region and a second region, the method comprising:
- generating, within a first three-dimensional camera, first image data depicting the object-of-interest within the first region and first non-image data representing the object-of-interest within the first region;
determining that the object-of-interest depicted in the first image data is corresponding to a same instance of the object-of-interest represented in the first non-image data by correlating the first image and first non-image data;
deriving first region coordinates of the instance of the object-of-interest from at least one of the first image and first non-image data;
employing a location of the first region and the first region coordinates to calculate first global coordinates of the instance of the object-of-interest;
generating, within a second three-dimensional camera, second image data depicting the object-of-interest within the second region and second non-image data representing the object-of-interest within the second region;
determining that the object-of-interest depicted in the second image data is corresponding to a same second instance of the object-of-interest represented in the second non-image data by correlating the second image and second non-image data;
deriving second region coordinates of the second instance of the object-of-interest from at least one of the second image and second non-image data; and
employing a location of the second region and the second region coordinates to calculate second global coordinates of the second instance of the object-of-interest, andwherein the object-of-interest is tracked over the global map as having moved from one of the first and second global coordinates to the other of the first and second global coordinates.
