3D building analyzer
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.

determining a scaling factor of the building object imagery based on a relative error to the determined scale of the selected architectural element for the identified architectural elements within the building object imagery;
constructing and scaling a multi-dimensional building model based on the building object imagery and the scaling factor; and
determining dimensions of a plurality of features of the multi-dimensional building model, the dimensions based on the scaling factor.
