What is Photogrammetry Software?
Photogrammetry is the science of extracting measurements (metry) from photographs (photogram). Photogrammetry has been around in some form since the second world war when photography started to take an import role in remote sensing.
Computational photogrammetry has been around since the early days of computers. The increasing power of computers, the introduction of the modern graphical user interface, and the introduction of the mouse in the 1980’s and 1990’s allowed computational photogrammetry to be run on everyday desktop computers.
It was now a tool accessible to a wide audience.
Traditionally, photogrammetry has been separated into aerial vs terrestrial (or close-range) but the recent advent of drones and UAVs and modern automated photogrammetry techniques has blurred that line.
PhotoModeler has a long history as a leading close-range photogrammetric tool. PhotoModeler introduced the concept of a desktop close-range photogrammetry product to the world in 1993 and has been a leader in technology since.
Many consider PhotoModeler to be the ‘father’ of modern desktop terrestrial photogrammetry.
Photogrammetry can be also considered to be ‘image measurement software’ combined with ‘3d modeling software’. Both 2D and 3D measurements and diagrams can be created from images and photographs. While not a full 3D CAD package, there are many 3D modeling features in PhotoModeler. Some applications (such as accident scene diagramming) may only need 2D diagrams or ortho-photos, which a full function photogrammetric platform like PhotoModeler can produce as well.
The drone / UAS industry has increased the interest in photogrammetry even further in recent years, and in 2016 Eos Systems (PhotoModeler Technologies) introduced the PhotoModeler UAS product to address this new market. The terrestrial, close-range methods and uses remain and are addressed in various application fields by the PhotoModeler Standard and PhotoModeler Premium products.
