An update on automatic 3D building reconstruction

Norbert Haala, Martin Kada
2010 ISPRS journal of photogrammetry and remote sensing (Print)  
From the beginning, fully automatic reconstruction systems were envisioned to fulfil the need for efficient data collection. However, research on automatic city modelling is still a very active area.  ...  For this purpose, airborne images or laser scans are used.  ...  Acknowledgement Martin Kada is indebted to the Baden-Württemberg Stiftung for the financial support of this research project by the Eliteprogramme for Postdocs.  ...

City-Scale Location Recognition

Grant Schindler, Matthew Brown, Richard Szeliski
2007 2007 IEEE Conference on Computer Vision and Pattern Recognition  
In particular we show that by carefully selecting the vocabulary using the most informative features, retrieval performance is significantly improved, allowing us to increase the number of database images  ...  This entails finding the location of a query image in a large dataset containing 3 × 10 4 streetside images of a city.  ...  Conclusion In addition to demonstrating a system for large-scale location recognition, we have shown two new results with respect to vocabulary trees.  ...

Extensive Exposure Mapping in Urban Areas through Deep Analysis of Street-Level Pictures for Floor Count Determination

Gianni Iannelli, Fabio Dell'Acqua
2017 Urban Science  
A specific algorithm allows attaching "number of floors" tags to the correct building in a dedicated GIS (Geographic Information System) layer, which is finally output by the system as an "exposure proxy  ...  In this paper, we leverage such methods to design a system for large-scale, systematic scanning of street-level pictures intended to map floor numbers in urban buildings.  ...  Fabio Dell'Acqua suggested training strategies and defined methods for building the GIS layers.  ...

Multi-View Stereo: A Tutorial

Yasutaka Furukawa, Carlos Hernández
2015 Foundations and Trends in Computer Graphics and Vision  
That is, for each pixel one has to do a 2D search in the other image.  ...  As for measures to tell how likely a candidate match is, there is a vast literature on how to build so called photo-consistency measures that estimate the likelihood of two pixels (or groups of pixels)  ...

Adaptive-Attentive Geolocalization from few queries: a hybrid approach [article]

Gabriele Moreno Berton, Valerio Paolicelli, Carlo Masone, Barbara Caputo
2020 arXiv   pre-print
We address the task of cross-domain visual place recognition, where the goal is to geolocalize a given query image against a labeled gallery, in the case where the query and the gallery belong to different  ...  To achieve this, we focus on building a domain robust deep network by leveraging over an attention mechanism combined with few-shot unsupervised domain adaptation techniques, where we use a small number  ...  This growth is confirmed by an increasing number of services that rely on visual place recognition systems, such as 3D reconstruction, consumer photography -"Where did I take these photos?"  ...

Visual and Object Geo-localization: A Comprehensive Survey [article]

Daniel Wilson, Xiaohan Zhang, Waqas Sultani, Safwan Wshah
2021 arXiv   pre-print
The concept of geo-localization refers to the process of determining where on earth some 'entity' is located, typically using Global Positioning System (GPS) coordinates.  ...  This paper provides a comprehensive survey of geo-localization involving images, which involves either determining from where an image has been captured (Image geo-localization) or geo-locating objects  ...  However, trigulation approaches use an Chaabane et al. [4] constructed a three-stage system that alternative method for condensing and geo-localizing repeat was mostly end-to-end trainable.  ...

2010 Multimedia tools and applications  
We show that the time is right for automating the geo-tagging process, and we show how this can work at large scale.  ...  Starting from an existing, geo-tagged dataset, we cluster images into sets of different views of the the same scene. This is a very efficient, scalable, and fully automated mining process.  ...  We end up with a total of 1, 146 images that we consider to be a single geo-cluster. The resulting visual clusters are 258.  ...
