3D Surveying Methods and Digital Information Management for Archaeological Heritage

BAR Publishing, 2022

3D Surveying Methods and Digital Information Management for Archaeological Heritage analyses in detail the methods and developments in 3D survey, with reference to the different areas of archaeological research. It examines the transition from traditional applications to 3D surveying, highlighting their advantages and disadvantages. Three-dimensional acquisition methods using photogrammetry and laser scanning are explored, as well as the most widely used systems for 3D data management, such as 3D GIS and innovative Building Information Modelling for archaeology. The theoretical analysis is contextualised in different archaeological scenarios (field survey, valorisation, and maintenance), and it is enriched by case studies that explain the application potential. This text is primarily for scholars interested in three-dimensional survey issues for archaeological contexts and students approaching graphic documentation aspects.

COMPUTER VISION TOOLS FOR 3D MODELLING IN ARCHAEOLOGY

International Journal of Heritage in the Digital Era, 2012

In archaeological Cultural Heritage study 3D modelling has become a very useful process to obtain indispensable data for documentation and visualization. Nowadays the continuous request to achieve photorealistic 3D models has led to testing different techniques and methodologies to speed up both data acquisition and the data processing phase. There are many examples of surveys conducted with the use of range-based and image-based techniques, but, in the last few years, the scientific research has been increasingly moving towards automatic procedures using Computer Vision approach to reduce time during data processing. Computer Vision approach offers a great opportunity for archaeological survey since it can be very easily used by existing Computer Vision interfaces such as 3D web services and open source or low cost software. The aim of this work is to evaluate the performance offered by Computer Vision interfaces for 3D survey of archaeological ruins using some 3D web-service tools and a low cost software like PhotoScan package. Some tests have been performed to analyze the geometric accuracy of 3D models obtained by 3D web-service tools and PhotoScan package through the comparison with a 3D model achieved by laser scanning survey.

Rapid 3D Recording of Archaeological Sites Found During Construction Development

2004

SUMMARY Current archaeological research in Greece is greatly enhanced from urban construction development that results in new archaeological finds. Whilst these findings are very important, financial pressures from during urban development result in either being destroyed or reburied to facilitate the construction of new structures. Invariably, valuable knowledge from such sites is lost forever. This paper discusses how modern surveying techniques can be used as foundation for preservation of cultural heritage. Specifically, the use of terrestrial laser scanning and digital photogrammetry to rapidly record detailed and definitive three-dimensional information from an early Helladic period (circa 2300BC) settlement in the southern area of Athens is discussed. The specific site has been exposed but will be completely destroyed due to a major road construction. The data capturing procedure during excavation is described and processing strategies are discussed. Finally, virtual models o...
