Technologies and methods for 3D reconstruction in archaeology

Abstract

Digital Modeling of archaeological sites and the inherent cultural heritage has proved to be a tool of great importance not only for discovery of data but also for recovery and understanding of data from the archaeological site remains. The irreversible and destructive nature of excavation can be mitigated by using the techniques of 3D digital modeling using the available hardware and methodologies of computer vision and reconstruction. The widespread adoption of 3D technologies have facilitated not only timely and accurate recording methods but also storage and reusability of data that can be further used for collaborative and reconstructive tasks. This allows for preservation of the excavated objects, artefacts and landscapes and also for inter-disciplinary research. In this work we have put forth the numerous techniques that are used for 3D reconstruction of objects and artefacts, creation of virtual environments of heritage sites and underwater excavation incorporating not only unearth artefacts but also maps and location information to form a virtual and immersive environment.
