What is Photogrammetry?
Photogrammetry can be used to create highly accurate maps and 3D models of terrain, and other features on the earth's surface. Photogrammetry can also be used to create accurate models of buildings, bridges, and other structures, allowing engineers and architects to design and plan construction projects more effectively.
Photogrammetry can be performed on a variety of images, including aerial photographs, satellite images, and ground-based photographs. The process typically involves the following steps:
Image acquisition: Photographs of the object or area of interest are taken using a camera or other imaging device. Multiple images are usually taken from different angles to ensure adequate coverage of the subject.
Image processing: The photographs are processed using specialized software to extract key features and create a 3D model or map. This can involve stitching together multiple images, identifying common features between images, and using mathematical algorithms to calculate the location and shape of the object or area.
Data analysis: The 3D model or map created from the photographs is analyzed to extract useful information. This can include measurements of size, volume, and distance, as well as information about the shape and topography of the object or area.
