ZRG: A High Resolution 3D Residential Rooftop Geometry Dataset for Machine Learning

Abstract

In this paper we present the Zeitview Rooftop Geometry (ZRG) dataset. ZRG contains thousands of samples of high resolution orthomosaics of aerial imagery of residential rooftops with corresponding digital surface models (DSM), 3D rooftop wireframes, and multiview imagery generated point clouds for the purpose of residential rooftop geometry and scene understanding. We perform thorough benchmarks to illustrate the numerous applications unlocked by this dataset and provide baselines for the tasks of roof outline extraction, monocular height estimation, and planar roof structure extraction
