El Mustapha Mouaddib received the Ph.D. degree in robotics and the Habilitation degree from the Université de Picardie Jules Verne, Amiens, France, in 1256 1991 and 1999, respectively. Since 2001, he has been a Full Professor with the same university. From 1995 to 2022, he was the Head of the Robotic Perception Group, and he was involved in research projects on omnidirectional vision and structured light. Since 2010, he has been the Leader of E-Cathedral, a multidisciplinary research initiative on digital heritage. He has served as an Associate Editor for the Conference Board of IEEE ICRA and IEEE/RSJ IROS, and for the IEEE Robotics and Automation Letters (2015–2018). His main research interests include computer vision and artificial perception for mobile robotics.

What can 3D do for architectural heritage? The case of Notre-Dame de Paris and Amiens cathedrals.

Beyond traditional arguments such conservation and cultural mediation, this talk will show special using of the 3D models for two major and big architectural buildings, Notre-Dame de Paris and Amiens cathedrals. The first example, by its nature after 2019 fire, forced us to work with existant data (acquired before fire) in order to help the diagnosis of this cathedral. The second one is different in the sense that there is no urgency and we can acquire 3D data as needed. In these two examples, special tools had to be developed to be able to exploit the 3D models. This task remains a difficult problem because of the 3D models size and the needed accuracy. We will explain these developed tools and the needed collaboration with art historians which is essential to fully exploit these tools.
