Photogrammetry is the art and science of extracting 3D information from photographs. The process involves taking overlapping photographs of an object, structure or space and converting them into 2D or 3D digital models.
Photogrammetry is often used by surveyors, architects, engineers and contractors to create topographic maps, meshes, point clouds or drawings based on the real world.
There are two primary types of photogrammetry: aerial and close-range.
The process of utilising aircrafts to produce aerial photography that can be turned into a 3D model or mapped digitally. Now, it’s possible to do the same work with a drone. Drones have made it easier to safely capture hard-to-access or inaccessible areas where traditional surveying could be dangerous or impractical.
Close-range photogrammetry is when images are captured using a handheld camera or with a camera mounted to a tripod. The goal of this method is not to create topographic maps, but rather to make 3D models of a smaller object.
ATFF used ReCap for accurate site capture, project visualisation and BIM creation for this Aiguilles hospital renovation project.
U.S. Bureau of Reclamation used ReCap and 3D modelling to help manage and protect the Glen Canyon Dam for generations to come.
Autodesk, Case Technologies and the Volterra-Detroit Foundation scanned key historical and archaeological sites in the ancient city of Volterra in Italy.
