Abstract
Systems and methods are described for creating three dimensional models of building objects by creating a point cloud from a plurality of input images, defining edges of the building object's surfaces represented by the point cloud, creating simplified geometries of the building object's surfaces and constructing a building model based on the simplified geometries. Input images may include ground, orthographic, or oblique images. The resultant model may be scaled according to correlation with select image types and textured.

-17. (canceled)
One or more non-transitory computer readable medium storing instructions that, when executed, cause a processor to execute operations comprising:
- receiving a plurality of ground-level images of a building object captured by a wireless capture device circumnavigating a building object;
- creating a point cloud with data points from the received ground-level images;
- selecting a plurality of vertices defining edges of at least one single planar surface within the point cloud;
- outlining the at least one single planar surface based on the selected plurality of vertices;
- creating a simplified facade geometry for the at least one single planar surface based on the outlined single planar surface;
- correlating data points within the point cloud to the outlined single planar surface;
- averaging a planar fit for the outlined single planar surface based on the correlated data points;
- and
- adjusting a position of the simplified façade geometry based on the average planar fit.
