Building 3D Mesh Extraction from Google Earth via Gaussian Splatting
A pipeline that produces the 3D surface mesh of a single building from Google Earth Studio multi-view imagery specified by name, address, or coordinates. It uses text-prompted foundation-model segmentation (GroundingDINO plus SAM2) with morphological mask refinement and contour simplification to isolate the building across views, then fits a 2D Gaussian Splatting model of its geometry and radiance and converts it to a mesh, requiring no labeled training data.
