In 2003, we undertook a little experiment with a Callidus 3D laser scanner and attempted, in a single day, to completely scan Knowlton Henge and church. This was generally regarded as being a bit of a foolish thing to try, but, as usual with all things Archaeoptics, we managed it quite comfortably (apart from the sunburn).

Perspective view of the Knowlton Henge 3D laser scan

Ably assisted by Tom Goskar of Wessex Archaeology, we collected just under 20 million points from the henge and church and produced a highly accurate fully-meshed 3D model.

This presentation was written for the April 2004 conference held at Creswell on Palaeolithic Rock Art as relating to the recent discoveries in Church Hole, Creswell Crags.

The presentation discusses, firstly, theory and suitability of the use of 3D scanners to record rock art, secondly, some results of Archaeoptics’ use of this technology in recording rock art at Creswell Crags.

This presentation was written for the October 2002 RSP Society conference on 3D acquisition technologies at Keyworth.

The presentation discusses many of the claims made by manufacturers on aspects of processing 3D data acquired by laser scanners with regards to alignment, merging and delivering high-quality 3D datasets.

This presentation was written for the M3 conference that ran simultaneously with the World of Geometics exhibition at Telford, May 2003.

The presentation discusses why 3D scanning is hard, contrary to advertised belief, and discusses the reasons why it is hard. Some solutions are presented and a bit of crystal ball gazing is also indulged in.

This paper was presented at the Remote Sensing and Photogrammetry Conference, November 2004. It discusses 3D laser scanning with respect to acquiring high-quality 3D datasets in difficult environmental conditions typically relating to archaeology and sculptural recording in the field.

The presentation contains many case studies generated from work undertaken over the years by Archaeoptics including Wemyss Caves, St. Paul’s Cathedral, Hermes of Praxiteles and Grimes Graves.

Recent advances in laser scanning technology allow for fast and efficient 3D documentation of cultural heritage artefacts and statues. The advantages are more evident when the objects are of large size and comprise complex surfaces and fine details. There is therefore a need to address clearly all the practical difficulties and issues that one has to consider when using this technology for the documentation of large archaeological statues. This paper describes a number of specific issues, from data capturing procedures to data management and processing, raised in a project aimed in producing a geometrically accurate 3D model of the ancient statue of Hermes by Praxiteles. Finally, results from the 3D solid model of the statue are also provided.

This paper was presented at the Computer Applications and Archaeology UK Conference, January 2005. It discusses research in the field of 3D laser scanning with respect to archaeology undertaken by Archaeoptics over the last 5 years.

The presentation contains many never seen before images generated from work undertaken over the years including Govan Old Parish Church, St. Paul’s Cathedral, Seahenge, Fylingdales Moor, Wemyss Caves and the Nesperrennub Mummy.
