Abstract: An apparatus for generating 3D geographical models includes a processor and memory storing executable computer program code causing the apparatus to at least perform operations including removing 3D points of a cloud depicting vertical structures in a geographic area responsive to analyzing a set of 3D points of the cloud. The points include data indicating geocoordinates of the geographic area. The computer program code further causes the apparatus to segment rooftops of vertical structures responsive to analyzing the set. The computer program code further causes the apparatus to delineate points of segmented rooftops responsive to extracting a boundary and a portion of rooftops. The computer program code further causes the apparatus to generate 3D geographic models depicting the geographic area based on connecting delineating points to a base including a height lower than heights of delineating points. Corresponding methods and computer program products are also provided.

Abstract: 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.

Abstract: An apparatus for generating 3D geographical models includes a processor and memory storing executable computer program code causing the apparatus to at least perform operations including removing points of a cloud depicting vertical structures in meshes of triangles detected in an area corresponding to a set of 3D points responsive to identifying triangles on vertical structures. The triangles include vertices corresponding to geocoordinates. The program code further causes the apparatus to interpolate non-vertical structures of triangles to generate a dense cloud of points. The program code further causes the apparatus to downward project delineated points of segmented rooftops to closest points of a ground to generate 3D polygonal models depicting geographical objects. The program code further causes the apparatus to generate texturized objects responsive to mapping triangle locations to the 3D polygonal models and assign texture to vertical structures and rooftops.
