Multi-View Stereo (MVS)-based 3D reconstruction is a major topic in computer vision for which a vast number of methods have been proposed over the last decades showing impressive visual results. Long-since, benchmarks like Middlebury [32] numerically rank the individual methods considering accuracy and completeness as quality attributes. While the Middlebury benchmark provides low-resolution images only, the recently published ETH3D [31] and Tanks and Temples [19] benchmarks allow for an evaluation of high-resolution and large-scale MVS from natural camera configurations. This benchmarking reveals that still only few methods can be used for the reconstruction of largescale models. We present an effective pipeline for large-scale 3D reconstruction which extends existing methods in several ways: (i) We introduce an outlier filtering considering the MVS geometry. (ii) To avoid incomplete models from local matching methods we propose a plane completion method based on growing superpixels allowing a generic generation of high-quality 3D models. (iii) Finally, we use deep learning for a subsequent filtering of outliers in segmented sky areas. We give experimental evidence on benchmarks that our contributions improve the quality of the 3D model and our method is state-of-the-art in high-quality 3D reconstruction from high-resolution images or large image sets.
