Assessing the Photogrammetric Potential of Cameras in Portable Devices
09/01/2012 | M. J. Smith, N. Kokkas
Applications: Accuracy and All

Many application specialists may find portable device (smartphone, tablet) cameras an attractive proposition where some modest photogrammetric capability would be useful. This paper investigates the geometric potential of these cameras for close range photogrammetric applications.

Automated Low-cost Photogrammetry for Flexible Structure Monitoring
09/01/2012 | Chih-Heng Wang, Jon P. Mills, Pauline E. Miller
Applications: All and Industrial Measurement

Long-term campaigns and flexible structures are regarded as two of the most challenging subjects in monitoring engineering structures. Long-term monitoring in civil engineering is generally considered to be labour intensive and financially expensive and it can take significant effort to arrange the necessary human resources, transportation and equipment maintenance. When dealing with flexible structure monitoring, it is of paramount importance that any monitoring equipment used is able to carry out rapid sampling. Low cost, automated, photogrammetric techniques therefore have the potential to become routinely viable for monitoring non-rigid structures.

Preserving Dinosaur Tracks on Dinosaur Ridge, Morrison, Colorado
12/01/2011 | Harold C. Schuch
ASPRS Photogrammetric Engineering and Remote Sensing, Dec. 2011, p. 1188
Applications: All, Archaeology, and Engineering & Science

“To what extent can terrestrial photogrammetry be used for displays andor engineering purposes? What is the state-of-the-art of the technology? What were the difficulties encountered, and how were they circumvented? These are the questions we asked as we set out to determine how best to photograph and preserve the dinosaur tracks on Dinosaur Ridge in Morrison, Colorado…”

Return to the scene of the crime — in 3D
11/24/2011 | Tom Cheshire
Wired.co.uk
Applications: All and Forensics & Accident Recon.

Over the past four years, Liscio, based in Toronto, has worked on nearly 60 cases around the world. Police use his reconstructions to test their theories of a crime. “You can start running different scenarios — what would happen if this person was a little to the left: would the trajectory still work? Or could the witness have actually seen the suspect at that point?” Liscio uses off-the-shelf 3D scanning equipment, such as the PhotoModeler Scanner made by EOS, to map entire crime scenes.

Digital Camera Calibration Using Images Taken from an Unmanned Aerial Vehicle
09/16/2011 | M. Pérez, F. Agüera, F. Carvajal
International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XXXVIII-1/C22, ISPRS Zurich 2011 Workshop, 14-16 September 2011, Zurich, Switzerland
Applications: Accuracy, All, Geology & Mining, and UAS / UAV / Drone

The aim of this work is the establishment of an efficient and accurate digital camera calibration method to be used in particular working conditions, as it can be found with our UAV (Unmanned Aerial Vehicle) photogrammetric projects.

SURVEYING A LANDSLIDE IN A ROAD EMBANKMENT USING UNMANNED AERIAL VEHICLE PHOTOGRAMMETRY
09/15/2011 | F. Carvajal, F. Agüera, M. Pérez
International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol. XXXVIII-1/C22, UAV-g 2011, Conference on Unmanned Aerial Vehicle in Geomatics, Zurich, Switzerland
Applications: All, Geology & Mining, Surveying, and UAS / UAV / Drone

Most of the works of civil engineering, and some others applications, need to be designed using a basic cartography with a suitable scale to the accuracy and extension of the plot. The Unmanned Aerial Vehicle (UAV) Photogrammetry covers the gap between classical manned aerial photogrammetry and hand-made surveying techniques because it works in the close-range domain, combining aerial and terrestrial photogrammetry, but also introduces low-cost alternatives.The aim of this work is developing of an accurate and low-cost method to characterize landslides located on the size of a road.

DIGITAL CAMERA CALIBRATION USING IMAGES TAKEN FROM AN UNMANNED AERIAL VEHICLE
09/14/2011 | M. Pérez, F. Agüera, F. Carvajal
International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol. XXXVIII-1/C22
Applications: All, Engineering & Science, Geology & Mining, and UAS / UAV / Drone

For calibrating the camera, an accurate determination of the interior orientation parameters is needed. For more accurate results, the calibration images should be taken under conditions that are similar to the field samples.The aim of this work is the establishment of an efficient and accurate digital camera calibration method to be used in particular working conditions, as it can be found with our UAV (Unmanned Aerial Vehicle) photogrammetric projects.
