\"photoscan\"<\/a><\/p>\n

Agisoft Photoscan is a stand-alone software product that performs photogrammetric processing of digital images and generates 3D spatial data<\/p>\n

Structure-from-motion photogrammetry is useful for many purposes including creating three-dimensional representations of surfaces, architectural features, excavation units, and portable objects. In Photoscan, users can also create orthophotos and DEMs if the images are acquired through UAVs.<\/p>\n

Basic Workflow<\/b><\/p>\n

Taking Photos<\/em>
\nAgisoft Photoscan creates point clouds from photographs by measuring the distances the locations of images to similar points on a surface (object or landscape). Thus, it is important to have multiple overlapping images of the same point on a surface from different angles. Photoscan must also know the GPS location of each image to work effectively. Fortunately, many devices built since 2010 automatically record the GPS locations of each photo taken, however users should check their device settings prior to taking photographs.<\/p>\n
