Statistical point pattern matching technique

A microprocessor based statistical method of point pattern matching in a point pattern matching computation machine, the method comprising:

• selecting a first subset of points identified from an orthogonal view of a structure;
• calculating an origin for an orthogonal point pattern that corresponds to the first subset of points;
• calculating an origin for an oblique point pattern that corresponds to a set of points identified from an oblique view of the structure;
• geometrically transforming the orthogonal point pattern to an oblique image plane, taking into account one or more camera orientations;
• repeating the acts of calculating an origin for the orthogonal point pattern and geometrically transforming, on a trial basis to generate point matching statistical data in an iterative fashion, in which each trial includes a different subset of points identified from the orthogonal view.

A point pattern matching computation engine, coupled to a networked microprocessor, for practicing embodiments of a statistical method of point pattern matching, the computation engine comprising:

• a non-transitory computer-readable memory having microprocessor-executable instructions stored thereon that, when executed by the microprocessor, cause the microprocessor to:
• acquire digital images from a plurality of different perspective views of a structure from an image source computing system via the network;
• perform the statistical method of point pattern matching using data from the digital images as input;
• create a 3D model of the structure from the digital image;
• and
• generate a report that contains the model of the structure.
