Abstract

A method for determining an absolute orientation in a global coordinate system is provided. In each grid position an image capturing device is directed to a selected object located in a scene. The method comprises: (A) reconstructing a scale model of the scene using point, line and/or region correspondences in multiple views of the scene obtained by the image capturing device placed in at least three grid positions; (B) obtaining location coordinates of at least three grid positions in the global coordinate system; and (C) determining a similarity transform from a photogrammetric coordinate system to the global coordinate system by determining rotation, translation and scale of the image capturing device for each grid position.
