Abstract
A system and method for creating enhanced floor plans. The method includes converting visual multimedia content into a plurality of frames, wherein the visual multimedia content shows a site, wherein each frame is a two-dimensional (2D) image showing a portion of the site; generating, based on the plurality of frames, a sparse three-dimensional (3D) model of the site, wherein the sparse 3D model includes a point cloud; geo-localizing the sparse 3D model with respect to a site layout model by identifying a plurality of matching features of the site layout model with respect to the sparse 3D model; and creating an enhanced floor plan based on the geo-localization, wherein the enhanced floor plan includes a plurality of floor plan points of the site layout model associated with respective portions of the sparse 3D model.
