1. A method of deriving at least one camera model, for security surveillance in at least one underlying terrain and georeferencing pixel coordinates in a camera view of a single security surveillance camera, the camera view being deficient of located landmarks in sufficient number or desired dispersion to produce the at least one camera model, said method comprising the steps of: a) obtaining, from the single security surveillance camera, a principal camera image comprising a principal view of the at least one underlying terrain, the principal view comprising at least two located landmarks; b) for each one of the at least two located landmarks of the principal view, producing, by at least one computer processor, a principal node associating physical coordinates of the located landmark in the at least one underlying terrain to pixel coordinates in the principal camera image; c) generating, by at least one computer processor, a principal nodelist comprising all available principal nodes of the principal view; d) obtaining from the single security surveillance camera, at least one auxiliary camera image comprising at least one auxiliary view of the at least one underlying terrain, the at least one auxiliary view comprising a plurality of located landmarks; e) for each one of the plurality of located landmarks of the at least one auxiliary view, producing, by at least one computer processor, an auxiliary node associating physical coordinates of the located landmark in the at least one underlying terrain to pixel coordinates in the at least one auxiliary camera image; f) generating, by at least one computer processor, at least one auxiliary nodelist comprising all available auxiliary nodes of the at least one auxiliary view; g) deriving, by at least one computer processor, from both the principal nodelist and the at least one auxiliary nodelist, at least two alignment nodes, each one of the at least two alignment nodes exhibiting respectively the same pixel coordinates in the at least one auxiliary camera image as the pixel coordinates in the principal camera image; h) geometrically aligning, by at least one computer processor, the principal view to the at least one auxiliary view through pairing of the at least two alignment nodes of the principal nodelist and the at least one auxiliary nodelist; i) generating, by at least one computer processor, an augmented principal nodelist by adding the nodes of the at least one auxiliary nodelist to the principal nodelist using a first set of geometrical computations, wherein the augmented principal nodelist comprises at least one enlarged set of located landmarks associated with the principal view; and j) using the augmented principal nodelist, obtaining, by at least one computer processor, the at least one camera model by at least one second set of geometrical computations; k) wherein the at least one camera model is utilized in security surveillance in the at least one underlying terrain.
