3 Scans of a Welsh castle

Castle Coch, just outside Cardiff was scanned using three scan positions in around 3 hours on site (including surveying BS/OBS coordinates and explaining to members of the public what we were doing). Two scans were outside and one 360 degree of the inner courtyard were made and coloured using the internal camera of the GLS-1000.
In addition to the scan, some digital photographs were acquired using a calibrated Canon EOS 5D camera to demonstrate point cloud colouring and dynamic photo interpolation in Topcon’s Imagemaster Pro. Dynamic interpolation effectively enables digitization of building detail in between scan points using localized automated photogrammetry.
