Close Range Photogrammetry-
A Land Survey Tool?
Photogrammetry is the science, technology and art of obtaining reliable information from noncontact imaging and other sensor systems about the Earth and its environment.
Close range photogrammetry applies to objects ranging in size from 1cm to 200m.With accuracies from 0.1mm in the manufacturing industries to 1cm for the architecture and construction industry.
Close Range Photogrammetry
A Brief History
Meydenbauer,
Photogrammetric Camera
(1867)
Meydenbauer, Wetzlar,
Germany (ca 1890)
It started with Albrecht
Meydenbauer in Germany.
- An architect and
building surveyor
- A near accident in
Wetzlar - 1858
- An idea – make the
measurements using
photographs
- Developed the first
metric cameras for
close range
photogrammetric work

Recent advances include:
- Terrestrial Laser Scanners
- Softcopy or Digital photogrammetric plotting systems
- Improved bundle adjustment software
- Improved self-calibration algorithms and software
- Highly accurate inertial positioning systems
- Sophisticated photogrammetric processing software
- Etc.
