Abstract
Determining the scale of building objects within collected imagery is determined by identifying architectural elements within stored building object imagery, determining dimensional ratios for the identified architectural elements, matching the identified architectural element to a known industry standard architectural element based on dimensional ratio comparisons and determining a scaling factor of the building object imagery based on relative error to the determined scale of the identified architectural elements. A three dimensional model of the building object constructed from said building object imagery may be scaled by the scaling factor, and dimensions such as measurements for its components determined.
