An evaluation of Deep Learning based stereo dense matching dataset shift from aerial images and a large scale stereo dataset

1 code implementation19 Feb 2024 Teng Wu, Bruno Vallet, Marc Pierrot-Deseilligny, Ewelina Rupnik

To address this challenge, we propose a method for generating ground-truth disparity maps directly from Light Detection and Ranging (LiDAR) and images to produce a large and diverse dataset for six aerial datasets across four different areas and two areas with different resolution images.

However it has two drawbacks: 1) the old data may be of higher quality (resolution, precision) than the new and 2) the coverage of the scene might be different in various acquisitions, including varying occlusions.

Learning Multi-View Aggregation In the Wild for Large-Scale 3D Semantic Segmentation

1 code implementation CVPR 2022 Damien Robert, Bruno Vallet, Loic Landrieu

Recent works on 3D semantic segmentation propose to exploit the synergy between images and point clouds by processing each modality with a dedicated network and projecting learned 2D features onto 3D points.

Deep Surface Reconstruction from Point Clouds with Visibility Information

1 code implementation3 Feb 2022 Raphael Sulzer, Loic Landrieu, Alexandre Boulch, Renaud Marlet, Bruno Vallet

Most current neural networks for reconstructing surfaces from point clouds ignore sensor poses and only operate on raw point locations.

Scalable Surface Reconstruction with Delaunay-Graph Neural Networks

1 code implementation13 Jul 2021 Raphael Sulzer, Loic Landrieu, Renaud Marlet, Bruno Vallet

We introduce a novel learning-based, visibility-aware, surface reconstruction method for large-scale, defect-laden point clouds.

A Synergistic Approach for Recovering Occlusion-Free Textured 3D Maps of Urban Facades from Heterogeneous Cartographic Data

no code implementations29 Aug 2013 Karim Hammoudi, Fadi Dornaika, Bahman Soheilian, Bruno Vallet, John McDonald, Nicolas Paparoditis

In this paper we present a practical approach for generating an occlusion-free textured 3D map of urban facades by the synergistic use of terrestrial images, 3D point clouds and area-based information.
