3D photogrammetry is a technique used to create three-dimensional models of objects or environments through the analysis of photographs. By capturing a series of overlapping images of a subject from different viewpoints, specialized software processes the images to identify common features and calculate their spatial positions in a 3D space. 3D photogrammetry finds applications in various fields such as mapping, surveying, cultural heritage preservation, archaeology, industrial measurement, and virtual reality content creation, providing detailed and accurate representations of physical spaces and objects.
