1. A method for defining a unique cuboid, comprising the steps of: imaging a cuboid employing first and second images; defining one or more of the cuboid object's vertices; matching the one or more defined vertices across multiple viewpoints to extract a three-dimensional vector for each of the one or more defined vertex combinations; extracting a diagonal connecting a first vertex of the one or more defined vertices and a second vertex of the cuboid; orthogonally projecting a first vertex of the cuboid and its associated edges to a canonical position; orthogonally projecting the extracted three-dimensional vector associated with the second vertex also into the canonical space; extracting a z-component of one or more of the sides defining the first vertex of the cuboid; orthogonally projecting the extracted diagonal to the canonical position; extracting one or more geometric relationships between one or more sides and the diagonal of the cuboid; and dimensioning the cuboid object in accordance with at least the one or more extracted angular relationships and the extracted diagonal.
