Abstract
Abstract. The research presented here is part of an on-going research focused on the 3D documentation of rock-cut Underground Built Heritage with a complex morphology and characterised by narrow spaces, the Hypogeum of Calaforno (province of Ragusa, Sicily). It is one of the most interesting prehistoric monuments in Sicily in terms of size and unique rock-cut architecture. Various digital techniques have been tested over the years on the site, to represent its spatiality, such as Laser Scanner and Structure from Motion. The proposed methodological approach for the knowledge and the documentation of this archaeological site is based on an interdisciplinary approach involving archaeological and engineering disciplines. This paper focuses on the use of expeditious techniques such as iMMS (indoor Mobile Mapping Systems) based on SLAM (Simultaneous Localization and Mapping) and on the comparison of different surveying equipment in order to verify data quality and accuracy, as well as the inherent advantages of using one technology over another in relation to the characteristics of the site. Through the global verification of TLS and SLAM model reliability, we maintain that such research can contribute to enriching the protocols surrounding the archaeological investigation of sites characterized by complex morphology, irregular surfaces, narrow spaces, specific chromatic features, scarce or total lack of lighting, and physical obstacles.
Highlights
The knowledge and documentation of complex archaeological heritage requires detailed and analytical metric investigation, which integrated digital surveying techniques have greatly improved
This paper focuses on the use and reliability of a recent expeditious technique, the indoor Mobile Mapping Systems based on Simultaneous Localization and Mapping (SLAM) technology
The experimentation aims primarily to evaluate the effectiveness and critical issues of the Mobile Laser Scanner mapping system based on Simultaneous Localization and Mapping (SLAM) BLK2GO by Leica Geosystem
Summary
The knowledge and documentation of complex archaeological heritage requires detailed and analytical metric investigation, which integrated digital surveying techniques have greatly improved. A multitude of 3D metric acquisition techniques and equipment are available, which differ in terms of function, size, acquisition time, accuracy level, and quality of the output model. For these reasons, it is important to understand their potential, limits, and applicability in relation to specific contexts and characteristics (Di Stefano et al, 2021). This research intends to contribute to the experimentation and comparison of different 3D survey techniques applied to a complex rock-cut architecture; an interesting case study with special morphological attributes.
