3D surface Approximation of the Entire Bayeux Tapestry for Improved Pedagogical Access
Résumé
The Bayeux Tapestry is an exceptional cultural heritage masterpiece by its size and the finesse of its details. Digitizing it raises a challenge, knowing that it is extremely fragile and thus lasers or invasive techniques are out of scope. In this work, we address this 3D-reconstruction challenge by introducing a pipeline to generate a high-resolution panorama of the Tapestry's geometry. It is based on a deep learning architecture that converts the RGB images of a pre-existing 2D panorama into a 2.5D normal map panorama. With a view to facilitating the Tapestry inclusive accessibility, we further show that coupling our 3D-reconstruction pipeline with a segmentation method allows the affordable and rapid creation of 3D-printed bas-reliefs, which can be explored tactilely by visually impaired people.
