Photogrammetric bridge deformation measurement

Project title

Pilot studies on photogrammetric bridge deformation measurement based on monoscopic image sequence analysis

Description

Photogrammetric techniques offer the potential of 3-D measurement of deformations of a large number of signalised points or natural texture on structural buildings by using at least two cameras or images taken from at least two different positions of one camera. The processing of deformation monitoring image sequences can be largely automated, and a precision potential in the order of 1 : 200,000 of the largest object dimension can be predicted. This allows to realize a fast and economic setup for spatio-temporal resolved deformation measurements of a very large number of targets.
