Photogrammetry is a technique used to extract three-dimensional (3D) informa on from two-dimensional (2D) photographs. It involves taking mulPple overlapping photographs of an object, structure, or space, and then using computer so ware to generate a 3D model. This model can be a 3D mesh, point cloud, or other digital representa ons of the object. Photogrammetry works on the principle of triangula on—calcula ng the di erent angles of sight from mulµple camera shots to determine the 3D loca on of points in the scene.
Photogrammetry is a technique that extracts three-dimensional (3D) information from two-dimensional (2D) photographs by capturing multiple overlapping images and processing them with specialized software based on the principle of triangulation to calculate the 3D location of points in a scene. This method creates accurate digital outputs such as 3D meshes, point clouds, and elevation models, making it highly valuable across various fields. It is used in archaeology and heritage preservation to document and model historical sites, in forensics to analyse crime scenes and reconstruct events, and in automotive and aerospace engineering to study vehicle dynamics and create 3D simulations. Additionally, engineering and construction industries rely on it for design, analysis, and visualization of structures, while mapping and surveying professionals use it to produce topographic maps, digital elevation models (DEMs), and orthophotographs.
