Deerhurst Photogrammetry

Project Description

Share

Archaeovision were used to digitise the South Cloister Wall at St Mary’s Priory Church in Deerhurst, Gloucestershire through photogrammetry. The church dates it’s origins back to 804 AD and is one of the finest and most complete buildings in England to survive from before the Norman Conquest. Its architectural history is complex and is still very much debated, but a substantial part of the building is now considered to belong to the first half of the 9th century.

Photogrammetry was used to create an accurate survey from which a scaled drawing of the stone detail present in the complex wall was completed. In total 1153 overlapping photographs were taken of the wall through a combination of a panoramic motorised tripod head and handheld photography. These were processed in Agisoft Photoscan and a scaled three dimensional model was produced for the production of a CAD drawing. Whilst on site we were able to identify new architectural features through our background in recording buildings and our understanding in their formation over time. These new areas were again found in the digitisation process. The CAD model produced is the most complete and most precise drawing of any part of the building
