2022 Virtual Keynote Speaker Series
Bruno Vallet
Creating digital twins of cities: from data acquisition to 3D modeling
Friday, 01.04.2022 at 14:00 CEST
ABSTRACT
The talk will adress various technical aspects of 3D city modeling from remote sensing data, with a focus on mobile mapping data.
First, the mobile mapping technique will be presented, then the issue of precise geolocalization and registration of such data will be adressed.
The talk will then focus on processing this data to analyse and reconstruct 3D city models: object detection, semantic analysis, 3D object, surface and structured reconstruction, texturing and change detection, with an emphasis on scaling.
Finally the talk will present a broad range of applications to these techniques.
BIOGRAPHY
Bruno Vallet graduated from école polytechnique and TelecomParisTech in 2004, and obtained a masters in artificial intelligence and shape recognition from Pierre et Marie Curie university. He completed his PhD in the Alice team of INRIA Nancy under the supervision of Bruno Lévy in the field of geometry processing. After obtaining his PhD in 2008, he joined IGN as a full-time researcher. Bruno Vallet successfully defended his research direction habilitation (HDR) from Université Paris Est in 2016. Since 2008, he has participated in several french and european research projects. Since 2019, Bruno Vallet coordinates the ACTE research team of the Lastig lab at IGN with areas of intert ranging from data acquisition, calibration and registration to 3D scene reconstruction and analysis, with a strong emphasis on mobile mapping. Finally, Bruno Vallet is co-chair of the International Society for Photogrammetry and Remote Sensing (ISPRS) Working Group II/4 on 3D Scene Reconstruction and Analysis.
