Protocols and Assisted Tools for Effective Image-Based Modeling of Architectural Elements

International audienceDomains related to documentation, conservation, restoration and enhancement of heritage objects use more and more digital 3D surveying. Image-based methods, due to their low-cost and accessibility, constitute an interesting alternative to traditional laser scanning surveys. However, these tools, often based on computer vision methods, are either difficult to use or not sufficiently accurate for scientific purposes. Within this context, this paper presents a photogrammetric pipeline in order to prove every heritage agent with a suitable and efficient solution for digitizing architectural and archaeological elements, taking into account the entire process, from the acquisition to the 3D result
