THREE-DIMENSIONAL BUILDING MODEL GENERATION BASED ON CLASSIFICATION OF IMAGE ELEMENTS

Methods, storage media, and systems for three-dimensional building model generation based on classification of image elements. An example method includes obtaining images depicting a building, with individual images being taken at individual positions about an exterior of the building, and with the images being associated with camera properties reflecting extrinsic and/or intrinsic camera parameters. Semantic labels are determined for the images via a machine learning model, with the labels being associated with elements of the building, and with the semantic labels being associated with two-dimensional positions in the images. Three-dimensional positions associated with the plurality of elements are estimated, with estimating being based on one or more epipolar constraints. A three-dimensional representation of at least a portion of the building is generated, with the portion including a roof of the building.
