Undercliffe and Photogrammetry

Real Virtual Worlds

 Students from Bradford Visualisation, a research centre in the School of Archaeological & Forensic Sciences, University of Bradford have been learning about photogrammetry and how it can complement traditional surveying techniques.

Photogrammetry is  the science of taking measurements from photographs, especially for recovering the exact positions of surface points. Photogrammetry dates to the mid-19th century and the simplest example is,  the distance between two points, that lie on a plane parallel to the photographic image plane, can be determined by measuring their distance on the image, if the scale of the image is known.

Led by Tom Sparrow, Research Fellow the first year  students visited Undercliffe Cemetery . Containing  a wide variety of monument types in terms of shape, size,  and materials, meant there were  a variety of problems associated with recording them.  The cemetery makes an ideal testing ground for different surveying and imaging methods.
