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.
Types of photogrammetry
There are two primary types of photogrammetry: aerial and close-range.
Close-range photogrammetry is when images are captured using a handheld camera or with a camera mounted to a tripod. The output of this method is not to create topographic maps, but rather to make 3D models of a smaller object.
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.
How is photogrammetry software used?
Building design and renovation
ATFF used ReCap for accurate site capture, project visualisation and BIM creation for this Aiguilles hospital renovation project.
ReCap Photo is our cloud-connected solution tailored for drone/UAV photo capturing workflows. Using ReCap Photo, you can create textured meshes, point clouds with geolocation and high-resolution orthographic views with level maps.
