Automated Low-cost Photogrammetry for Flexible Structure Monitoring
1 September 2012 | Chih-Heng Wang, Jon P. Mills, Pauline E. Miller | International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XXXIX-B5, 2012 XXII ISPRS Congress, 25 August – 01 September 2012, Melbourne, Australia
Fields: Industrial Measurement and QA  |  Featuring PhotoModeler Scanner 6

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.

Precise positioning surveillance in 3-D using night-vision stereoscopic photogrammetry
26 April 2011 | Jason M. Schwartz | Display Technologies and Applications for Defense, Security, and Avionics - V. (S.P.I.E.) 8042
Fields: Engineering and Science  |  Featuring PhotoModeler Scanner 2010

A 3-D imaging technique is presented which pairs high-resolution night-vision cameras with GPS to increase the capabilities of passive imaging surveillance. Camera models and GPS are used to derive a registered point cloud from multiple night-vision images. These point clouds are used to generate 3-D scene models and extract real-world positions of mission critical objects. Analysis shows accuracies rivaling laser scanning even in near-total darkness. The technique has been tested on stereoscopic 3-D video collections as well. Because this technique does not rely on active laser emissions it is more portable, less complex, less costly, and less detectable than laser scanning. This study investigates close-range photogrammetry under night-vision lighting conditions using practical use-case examples of terrain modeling, covert facility surveillance, and stand-off facial recognition.

MONITORING THE TESTING, CONSTRUCTION AND AS-BUILT CONDITION OF MEMBRANE STRUCTURES BY CLOSE RANGE PHOTOGRAMMETRY
21 June 2010 | Chih-Heng Wang, Jon P. Mills, Peter D. Gosling, Ben Bridgens, Robert J Grisdale; School of Civil Engineering and Geosciences, Newcastle University | International Archives of Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol. XXXVIII, Part 5
Fields: Engineering and Science, Industrial Measurement and QA, Accuracy  |  Featuring PhotoModeler Scanner 6

Engineering deformation monitoring requires techniques which can produce high precision and accuracy, reliable measurements at good temporal resolution and fast processing speed. Moreover, 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. Such requirements are especially true for monitoring non-rigid membrane structures (defined in this paper as covers or enclosures in which a fabric surface is pre-shaped and pre-tensioned to provide a shape that is stable under environmental loads). Low cost, automated, photogrammetric techniques therefore have the potential to become routinely viable for the structural monitoring of non-rigid membrane structures in the future. This research is investigating the use of close range photogrammetry to be applied at all stages of membrane structure engineering, from materials testing, through dimensional control in construction to in-situ, as-built monitoring of the finished construct.

Recent Developments in Close Range Photogrammetry (CRP) for Mining and Reclamation
2010 | Maynard L. (Mike) Dunn, Jr., Geologist, Office of Surface Mining and Reclamation Pittsburgh, PA
Fields: Geology and Mining  |  Featuring PhotoModeler Scanner 6

This report presents the potential of close range photogrammetry for mining and reclamation. The miningreclamation community depends on accurate mapping for almost all activities. Traditional ground surveys are adequate for small, uncomplicated jobs but at some point, the size andor complexity of a project makes it more economical to have a site flown (mapped using aerial photogrammetry). Because of cost, most projects are only flown at the start and less often when completed. Close Range Photogrammetry (CRP) offers much potential for measuring features that cant or arent being measured otherwise.

Fields: Archaeology  |  Featuring PhotoModeler Scanner 6

The study of archaeological artifacts requires a great care for the object. Current technologies allow the study of the object scanned in three dimensions. Hence, the digitization of objects has almost become compulsory for simplicity of study and analysis. Hence a low cost solution susceptible of being operated with reasonable effort could contribute to popularize 3D acquisition tools. In our study, we focus particularly on two solutions: David Laserscanner and PhotoModeler Scanner. Both systems come from two different techniques: laser scanning and photogrammetry.

Fields: Engineering and Science, Industrial Measurement and QA  |  Featuring PhotoModeler 5

Photo modeling technology has progressed to the point where a dimensionally accurate 3D model can be economically constructed from a series of digital photographs of a structure. We show in this article how a photo model of a structure can be used to create an FEA model from which the modes of the structure can be calculated. The FEA mode shapes obtained from the photo models are then compared with the experimentally derived mode shapes of each structure to demonstrate the validity of this approach to FEA modeling.

Fields: Geology and Mining, Engineering and Science  |  Featuring PhotoModeler Scanner

Slope failures and landslides associated with earthquakes and typhoons are major natural hazards in Taiwans mountain highways. This paper attempts to apply photogrammetry technique to carry out speedy in-situ survey. We firstly create the three-dimensional (3D) model of a brick wall and validate that the average error is 0.28 mm in the measured distance. Afterward, the same measurement procedures are applied in an in-situ mudstone slope. The average error in the estimated distance is 0.41cm. Therefore, the investigating result guarantees the accuracy of applying Photogrammetry to investigate the geometry of in-situ failed slope.

Tools for Field Surveying
17 August 2003 | Evan H. Shu, FAIA | Architecture Week
Fields: All - Magazine Reviews, Architecture  |  Featuring PhotoModeler 4

"When architects begin a renovation or addition to a building for which no plans are available, they are often faced with the tedious chore of measuring existing conditions and creating plans from scratch. Not too long ago, the most efficient process involved a three-person team one with a clipboard and two with a measuring tape, calling out distances. But in recent years, several aids have been developed that make it easier, even for one person alone, to make measurements fast and accurately."

Three-dimensional morphometric measurements of reef corals using underwater photogrammetry techniques
11 August 2001 | J. Bythell, Department of Marine Sciences and Coastal Management, University of Newcastle, P. Pan, Department of Maritime Studies and International Transport, University College of Wales at Cardiff, and J. Lee, Virtually Unlimited, Kingskerswell, UK | Coral Reefs, Springer-Verlag, Issue: Volume 20, Number 3
Fields: Biology  |  Featuring PhotoModeler 4

The authors describe a novel technical approach to accurately measure surface area and other morphological characteristics of corals and similar irregular objects from underwater photography. A standard Nikonos camera system was used with a slide-scanner to produce multiple overlapping images of the object. PhotoModeler software was used to process the images and build a 3-D model of the object, which was subsequently analyzed using 3-D computer-aided design (CAD) packages.

Accident Scene Diagramming Using New Photogrammetric Technique
24 February 1997 | Stephen Fenton, Richard Kerr, Knott Laboratory, Inc. | SAE 970944
Fields: Forensics and Accident Recon.  |  Featuring PhotoModeler 3

One of the challenges for accident reconstructionists is creating accurate accident scene diagrams from photographs, esp when only one photograph is available, and information about the camera that took the photograph is not available. The authors present a technique that enables the user to create an accurate accident scene diagram from only one unknown photograph of the accident scene, by using a combination of processes called Inverse Camera Projection and Photographic Rectification.
