"photogrammetry"的定义和意义

What is "photogrammetry"?

Photogrammetry is the process of making precise measurements and creating maps or three-dimensional models from photographs, usually taken from the air or ground. By analyzing multiple photos of the same object or area from different angles, photogrammetry can determine the exact positions, shapes, and sizes of objects. This technique is widely used in fields like cartography, architecture, engineering, and archaeology to create accurate representations of landscapes, buildings, and other structures. It helps in tasks like surveying land, reconstructing historical sites, and even in virtual reality applications.
