Scottish National Portrait Gallery
One of the major advantages of multi-image photogrammetry is that it can be applied to subjects of any scale. Using exactly the same camera and workflow we applied for the Lewis Chessman we carried out a rapid survey of the Scottish National Portrait Gallery, next door to our Edinburgh office.
The survey was conducted in less than ten minutes on the 25th October 2013, using a compact handheld camera and processed on a Wessex Archaeology geomatics workstation. The technique is faster and more accurate than traditional rectified photography and can be used to create accurate orthographic projections in less time and for a lower cost than laser scans.
