We are pleased to be able to share some of our recent work in Monmouthshire. We were asked by Cadw to undertake a photogrammetric survey at Tintern Abbey (SAMMm102). The aim of the survey was to produce accurate, measured 3D photogrammetric modelling of the east wall of the Chapter House and east facing elevation of the Monk’s Dortor/Day Room. The survey areas were situated adjacent (east) to the mid-12th century cloister and forms part of challenging restoration work being carried out by IBEX Technical Access LTD. We also had time to take a quick drone video during lunch, you can view the video here.
The Monk’s Day Room survey created a dense point cloud of over 18 million points with a mean RMS error of 0.8cm. The Ground Sampling Distance (GSD) achieved was a great 0.43cm/pixel. The 3D model of the Monk’s Day Room can be viewed here.
The Chapter House survey created a dense point cloud of over 36 million points with a mean RMS error of 0.8cm. The Ground Sampling Distance (GSD) achieved was a great 0.38cm/pixel. The 3D model of the Chapter House can be viewed here.
