Building Reconstruction From High-Resolution Multiview Aerial Imagery

In this letter, we propose a novel method to reconstruct accurate building structures from high-resolution multiview aerial imagery, using layered contour fitting (LCF) with a density-based clustering algorithm. Initially, the complicated 3-D scene is reconstructed by a probabilistic volumetric modeling algorithm. Subsequently, the reconstructed 3-D scene model is projected into layer images based on the height information. At last, we combine an extended layered density-based clustering approach with a generative LCF approach to remove noise and extract accurate building contours in every layer image at the same time. The final accurate 3-D building model is generated from these contours in layer images with a smoothing operation. Experiments on the aerial image sets demonstrate effectiveness and precision of our method.
