3D Modelling Through Photogrammetry in Cultural Heritage
- 481 Downloads
Photogrammetry is a technique for estimating the exact position of surface points of an object by using multiple photographs. Aerial photogrammetry is based on the acquisition of photographs of a certain area from the sky, commonly by placing cameras on a plane, drone, or even a satellite, to create a topographical map or terrain model. Terrestrial photogrammetry aims at taking 3D measurements of an object, using photographs of that object taken from a camera positioned on the surface of the earth. Terrestrial photogrammetry is also referred to as close-range photogrammetry when the photographs of the object are taken at a close range.
Photogrammetry is a manual process which requires in-depth understanding since it involves several aspects; for instance, the focal length and position of the camera when taking each photograph will impact the quality of the end result. However, recent technological advancements...
