Photogrammetry is the art of making measurements from photographs. The input being photographs, and the output is typically an orthographic map, orthographically projected elevation (to scale) or a 3D model of a building, structure, sculpture – anything really!
By stiching together photographs taken from the ground and sky we can cover almost all eventuality.
See the example set out below of the Day Mark at Kingswear. This was created using a series of 24 photographs taken from the ground. We then processed the images using out photogrammetry software, aligned them and went on to create a 3D point cloud and 3D mesh, along with orthographic images of the elevations. This was done as an exercise to test out new equipment, but could be utilised to create libraries of statues/sculptures/scheduled ancient monuments – orthographic imagery of listed buildings or buildings of specific interest.
