Structure Model Segmentation from a Three Dimensional Surface

摘要

Segmenting a three dimensional (3D) model of a structure may involve distinguishing vertically oriented surface elements from horizontally oriented surface elements of a three 3D surface representing a geographic area. The geographic area involves at least one structure. Segmenting a 3D model may also involve distinguishing ground surface elements from rooftop surface elements of the horizontally oriented surface elements of the 3D surface. Segmenting a 3D model may then involve associating the vertically oriented surface elements with the rooftop surface elements to form at least one segmented model of the at least one structure.

1. A method comprising:
identifying data indicative of a three dimensional (3D) surface representing a geographic area, the 3D surface comprising surface elements and the geographic area comprising a structure having a geographic footprint smaller than the geographic area; distinguishing, by a processor, vertically oriented surface elements from horizontally oriented surface elements of the 3D surface; distinguishing ground surface elements from rooftop surface elements of the horizontally oriented surface elements of the 3D surface; and associating the vertically oriented surface elements with the rooftop surface elements to form a segmented model of the structure.
