Digital photogrammetry is a field of photogrammetry in which aerial and ground photographs, obtained either directly from digital cameras or from scans of photogrammetric photographs. These photographs are processed by special software. Digital photogrammetry is an important step in the development of this field, because of the application of computers. Photogrammetric methods make working with an object more comfortable, as no direct contact with the object is required. Methods and solutions employed by todays photogrammetry have become very useful in many engineering and industrial aspects (measurements of deformations, surveying measurements).
