Method and system for geometry extraction, 3D visualization and analysis using arbitrary oblique imagery

A non-transitory computer-readable medium having a set of instructions stored therein which when executed cause a machine to perform a set of operations comprising:

• receiving a set of tie points for a first image;
• iterating through sets of camera parameters for the first image;
• calculating a least squares fit value for each of the sets plurality of camera parameters;
• selecting a set of camera parameters from the sets with a least error in the least squares fit value;
• and
• calculating two-dimensional coordinates for the pixel of the first image based on an overlapping area of an orthorectified image;
• calculating a geo-location for a pixel of the first image using the selected set of camera parameters;
• wherein the first image is an oblique image.
