True Gigapixel RTI

The ACRG has always been an integral part within the recent development of RTI. ACRG's involvement began with the AHRC funded RTISAD project where we piloted the technique on inscribed ancient documents and archaeological artefacts. We likewise raised awareness of RTI in research and public communities in the UK. Continue reading →

Update on the Hoa Hakananai’a Statue

In 2012 ACRG members, James Miles and Hembo Pagi, completed a series of RTI captures and a photogrammetry model of the Easter Island Statue, Hoa Hakananai'a, which is currently housed in the British Museum. Since then, in collaboration with Mike Pitts, we have examined the results of these RTI files and compared them with the photogrammetry model. A brief discussion of this work can be seen in a previous blog post. Continue reading →

Netley Abbey

In January of this year myself and Dan Joyce completed a series of recording techniques at Netley Abbey, including time of flight and phase scanning, photogrammetry and Reflectance Transformation Imaging. The work was organised by Dan in collaboration with English Heritage for his individually negotiated topic for his masters degree. Continue reading →

The voice of Easter Island in the British Museum

Over the past year myself, Hembo Pagi and Graeme Earl from the ACRG have been working with Mike Pitts, editor of the British Archaeology Journal, on the Hoa Hakananai'a statue at the British Museum. The work included the production of a virtual model, through photogrammetry and a series of Reflectance Transformation Images to study the petroglyphs found on the statue. Continue reading →

Winchester Cathedral RTI Community Day

On the 1st February I hosted a community RTI (Reflectance transformation imaging) day at Winchester Cathedral. The day was based around the introduction of this useful technique to the Cathedral guides, the Master students based in the computing research group and the lifelong learning students that have taken recent evening classes at the University.

How to fix incorrectly aligned RTI images

Often, when capturing a RTI data set, especially when using a cable, the images captured can be out of place, resulting in an incomplete data set. The following is a how to guide to fix this problem using Photoshop. The first step is to load all of the files into Photoshop using the correct tool. This is done by clicking the file tab, then Scripts and then "Load files into Stack". Continue reading →

Royal Archaeological Institute meeting at the Society of Antiquaries of London

Yesterday myself, Hembo Pagi and Gareth Beale gave an hour's talk at the Royal Archaeological Institute meeting at the Society of Antiquaries of London. The talk was based on the recent work that the research group has completed and was arranged by their president Professor David Hinton. The talk was based on recent Computed Tomography scanning that ACRG and the MuVis centre has completed, triangulation and time of flight laser scanning and numerous examples of photogrammetric modelling.

Laser Scanning at Portus

In the past week myself and Gareth Beale have spent time capturing the subterranean areas of  the Imperial Palace at Portus. We have been trialing the use of the Leica Scan Station C10 for archaeological documentation and the results so far appear very impressive. All archaeological remains are subject to constant deterioration, this is especially true of substantial architectural remains such as the Imperial Palace. Continue reading →

GigaPan work at Bodiam Castle

Between the 4th and the 24th August I spent some time at Bodiam Castle and the surrounding area completing a geophysical and building survey of the castle and grounds. The work is a collaboration between North Western University, Chicago, USA (Prof Matthew Johnson) and Southampton (Kris Strutt) and has been used as a teaching aid to first, second and third years. I have spent three years working at this wonderful site and I have never taken a single photograph of the castle. Continue reading →

ACRG Collaboration with the Department of Classics, Cambridge

I have recently completed some work with Dr Rebecca Flemming in the hope of a future collaboration between ACRG and the department of Classics at the University of Cambridge. The work that I have completed relates to the laser scanning of Roman anatomical votive terracottas. The work is in its early stages but I have included some images of the three dimensional models that I have created from the recent laser scan work on objects that are similar in shape and size.
