1 Close Range Photogrammetry- A Land Survey Tool? Trimble Navigation Limited Colorado, USA Presenter George Southard 29 January 2015

2 Close Range Photogrammetry 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.

3 A Brief History It started with Albrecht Meydenbauer in Germany. - An architect and building surveyor - A near accident in Wetzlar An idea make the measurements using photographs - Developed the first metric cameras for close range photogrammetric work Meydenbauer, Wetzlar, Germany (ca 1890) Meydenbauer, Photogrammetric Camera (1867)

4 Close Range Photogrammetry The Plane Table era of photogrammetry Meydenbauer Metric Cameras 1890 Finsterwalder phototheodolite 1895 Zeiss Jena Phototheodolite 1904

5 Close Range Photogrammetry The Analog era of photogrammetry Pulfrich, stereocomparator, (1901) Zeiss SMK40 Stereometric cameras 1950s Zeiss Terragraph Stereoplotter 1950s

6 Close Range Photogrammetry The Analytical era of photogrammetry Wild, BC2 Analytical stereoplotter, (1984) Manufacturing Industry photogrammetry (ca. 1980)

7 Close Range Photogrammetry The Digital era of photogrammetry 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. And NOW! Trimble Navigation s latest tool the V10 Panoramic Imaging Rover
