About the research centre or Inria department
The Inria centre at Université Côte d'Azur includes 37 research teams and 8 support services. The centre's staff (about 500 people) is made up of scientists of different nationalities, engineers, technicians and administrative staff. The teams are mainly located on the university campuses of Sophia Antipolis and Nice as well as Montpellier, in close collaboration with research and higher education laboratories and establishments (Université Côte d'Azur, CNRS, INRAE, INSERM ...), but also with the regiona economic players.
With a presence in the fields of computational neuroscience and biology, data science and modeling, software engineering and certification, as well as collaborative robotics, the Inria Centre at Université Côte d'Azur is a major player in terms of scientific excellence through its results and collaborations at both European and international levels.
Context
The job environment is the one of the CP4SC project, a collaborative effort that focuses on developing a cloud platform for smart cities. We will collaborate with Oslandia on C++ software components for urban reconstruction from 3D point clouds and GIS (Geographical Information Systems) data, based on the CGAL library and SFCGAL (a wrapper around CGAL that implement 2D and 3D operations on OGC (open geospatial consortium) standards models).
Assignment
We will explore the automated generation of 3D urban models, either from measurement data such as 3D point clouds or from GIS data. This requires a pipeline of algorithms ranging from analysis to processing of large-scale data, through semantic classification and reconstruction of 3D meshes from data that are possibly heterogeneous, incomplete and defect-laden. Measurement data such as 3D point clouds may be acquired on a building, a city block or an entire city. The reconstruction algorithms must generate adjustable levels of detail with fine-grain and adjustable balance between complexity, resolution and approximation. The CGAL library already offers components for the aforementioned pipeline, and the SFCGAL library provides a wrapper around some of the CGAL components. The objective is to complement the pipeline for urban reconstruction and to extend the SFCGAL library.
