Photogrammetry is a method of using photographs to measure and analyze objects or landscapes. It involves taking multiple photographs of an object or scene from different angles and then using specialized software to analyze the photographs and create a 3D model or map of the object or landscape.
This technique is often used in fields such as surveying, architecture, and archaeology to create accurate, high-resolution 3D models or maps. It can also be used in film and video game production to create realistic 3D environments.
In this case, the object we wished to scan was within a large body of water and it is usually not visible or accessible due to the water level. During a period of low water, we were able to access the location and generate our 3d model. This model allows us to study the site even when it is lost below the water of the Loch where it lies.
