Structure from Motion and Archaeological Excavation: Experiences of the Via Consolare Project in Pompeii

The last decade of advances in Image-Based Modeling (IBM) data acquisition based on Structure from Motion (SfM) have made it possible as never before to record excavated archaeological deposits, historical architectural remains, artifacts, and geographical surroundings the field. Armed only with digital cameras low-cost or open-source software, researchers can now produce accurate point clouds millions points, capturing information high-resolution detail. But what changes will IBM really bring standards, requirements, expectations practical field methodology for projects operating shoe-string budgets? Since 2010, Via Consolare Project, a small research project State level University, has employed an entirely “free academic use” pipeline variety features Insula VII 6 “Villa delle Colonne mosaico” Pompeii. Ranging surviving architecture, rubble fill layers, interiors inaccessible cisterns drains, this work been carried out preparation eventual coordination these into 3D GIS all recorded stratigraphy. Rarely were sufficient resources available dedicated equipment personnel be devoted task. While implementation, even low-budget excavation environment, confirmed that technology indeed augment documentation provide investigation opportunities would otherwise impossible, failed replace traditional handdrafted recording techniques was found present significant challenges number hidden costs. This emphasizes need appropriate cautious planning especially limited means.
