Deformation Measurement of a Railroad Bridge Using a Photogrammetric Board without Control Point Survey

Abstract

We propose a photogrammetric board to measure the deformation of a railroad bridge using close-range photogrammetry. The method can be used to compute the exterior orientation parameters and determine three-dimensional (3D) coordinates from images without measuring the control points. The bridge deformation measured using the proposed method was compared to that measured with a 3D laser tracker. The measurement error was within 1 mm, and the proposed method can measure the deformation of an I-plate girder of a railroad bridge. This method may be an alternative to precise stability inspections and bridge inspections.

Workflow for Off-Site Bridge Inspection Using Automatic Damage Detection-Case Study of the Pahtajokk Bridge

“…Recently, Popescu et al [4] compared modern techniques and found close-range photogrammetry (CRP) to be more efficient and costeffective for bridge inspection. A summary of the obtained accuracy from modern and traditional methods over the last twenty years is presented in Figure 1 [5][6][7][8][9][10][11][12][13][14][15][16][17]. Off-site bridge inspection can be carried out using unmanned aerial vehicles (UAVs) equipped with sensors such as laser scanners, and infrared, ultrasonic, or digital single-lens reflex (DSLR) cameras.…”

Stereophotogrammetry for 2-D building deformation monitoring using Kalman Filter

“…In every epoch, an automatic target localization algorithm, based on a combination of normalized cross correlation and least squares matching was applied in order to measure image point coordinates' pre-signed points on the beam. Also, Lee and Han (2018) utilized the 3D coordinates of targets on a bridge obtained from photogrammetric measurements to determine the deformation on a bridge by analysing the differences between coordinates at different epochs with specified baseline coordinates. The study used a photogrammetric board to determine the interior and exterior orientation parameters.…”

Photogrammetric Solution for Analysis of Out-Of-Plane Movements of a Masonry Structure in a Large-Scale Laboratory Experiment

“…Currently, the remote sensing discipline offers several solutions to analyze the deformation suffered by various structures from a contactless perspective. Examples of its applicability range from large civil infrastructures such as dams [1][2][3] or bridges [4][5][6]-even in a dynamic loading scenarios [7,8]-to laboratory specimens [9][10][11][12][13][14][15][16][17]. Within this context, the laser scanning technology is placed as the most used remote sensing approach [1][2][3]5,9,13] as it can directly provide high-density three-dimensional (3D) data in the form of point clouds.…”

“…In addition to this, its measurement principle-based on the emission and reception of a laser beam-within the necessity of having a dense point cloud, requires the investment of several minutes to capture the whole scene. This issue restricts the use of this technology to those cases in which the structure is completely static [3,9,13,18,19].Another potential approach for the analysis of changes and deformation in structures that does not share this restriction is photogrammetry [4,[6][7][8][10][11][12]14,15,17,[20][21][22]. This approach, in contrast to laser scanning, is relatively low-cost as it is possible to obtain reliable results by means of common digital single-lens reflex (DSLR) cameras [6,15,16,21,22].…”
