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.
