Titus ZAHARIA<\/strong>, Professor, T\u00e9l\u00e9com SudParis, FRANCE – Directeur de these R\u00e9sum\u00e9 :<\/strong><\/p>\n\n\n\n Cette th\u00e8se aborde les d\u00e9fis relatifs \u00e0 la mise en \u0153uvre du placement et de l’alignement du contenu virtuel sans marqueurs pour la R\u00e9alit\u00e9 Augment\u00e9e (RA) dans des environnements industriels d’assemblage de chaudi\u00e8res. Malgr\u00e9 les potentiels b\u00e9n\u00e9fices de la RA pour l’industrie, incluant une production accrue ainsi qu’une formation interactive et plus efficiente des op\u00e9rateurs, son utilisation reste limit\u00e9e dans les environnements de production complexes. Une des limitations technologiques r\u00e9side dans l’incapacit\u00e9 des approches traditionnelles d’alignement du contenu virtuel, tirant parti de marqueurs physiques, \u00e0 op\u00e9rer sur des lignes de production enti\u00e8res, notamment, lorsqu’elles sont compos\u00e9es d’objets d’int\u00e9r\u00eat ou de structures d’assemblage mobiles. \u00c0 travers l’investigation de diverses approches de vision par ordinateur, notre travail aboutit au d\u00e9veloppement d’une pipeline innovante combinant les Neural Radiance Fields et les m\u00e9thodes d’estimation de position 6D dites \u00ab zero-shot \u00bb. Cette solution permet l’alignement du contenu virtuel sans marqueurs et sans n\u00e9cessiter de donn\u00e9es d’entra\u00eenement labellis\u00e9es ni de mod\u00e8les CAD pr\u00e9existants. L’approche propos\u00e9e d\u00e9montre des performances robustes sur diff\u00e9rents mod\u00e8les de chaudi\u00e8res et \u00e9tapes d’assemblage. Nos contributions vont au-del\u00e0 de la mise en \u0153uvre technique pour inclure des id\u00e9es concernant le d\u00e9ploiement pratique de solutions de vision par ordinateur dans des environnements industriels, ouvrant la voie \u00e0 une adoption plus g\u00e9n\u00e9ralis\u00e9e de la RA dans le contexte de l’industrie 4.0. Abstract :<\/strong><\/p>\n\n\n\n This thesis addresses the challenge of implementing markerless Augmented Reality (AR) in manufacturing environments, focusing on boiler assembly lines. While AR technology shows great promise for improving industrial efficiency through operator training and assistance, its adoption has been limited by difficulties in handling complex production environments. Traditional approaches using markers become impractical when scaling across entire production lines, especially with dynamic objects and assembly structures. Through systematic investigation of various computer vision approaches, from lightweight neural networks to advanced 3D reconstruction techniques, our work culminates in an innovative end-to-end pipeline that combines neural rendering and zero-shot pose estimation techniques. This solution enables markerless AR without requiring extensive manual annotations or pre-existing 3D models, addressing key barriers to industrial AR adoption. The proposed approach demonstrates robust performance across different boiler models and assembly stages, achieving remarkable results in real production conditions. Our contributions extend beyond technical implementation to include valuable insights for deploying computer vision solutions in industrial settings, paving the way for more widespread adoption of AR technology in Industry 4.0 manufacturing environments.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale : Ecole Doctorale de l’Institut Polytechnique de Paris et le Laboratoire de
