Displacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)
There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...
متن کاملDisplacement/strain measurements using an optical microscope and digital image correlation
Dwayne D. Arola University of Maryland Baltimore County Department of Mechanical Engineering Baltimore, Maryland 21250 Abstract. We conduct displacement/strain measurements on the microscale using light microscopy and digital image correlation DIC . Errors in the measurements attributed to the optical arrangement and aberration induced at high magnification are identified using a warping functi...
متن کاملImproved Newton-Raphson digital image correlation method for full-field displacement and strain calculation.
The two-dimensional in-plane displacement and strain calculation problem through digital image processing methods has been studied extensively in the past three decades. Out of the various algorithms developed, the Newton-Raphson partial differential correction method performs the best quality wise and is the most widely used in practical applications despite its higher computational cost. The ...
متن کاملHigh resolution digital image correlation using proper generalized decomposition: PGD-DIC
A new method is proposed to measure the finite element (FE) displacement field from a deformed image in comparison to a reference one. In opposition to standard FE approaches, the unknown displacement is sought as a sum of products of separated dimensions functions. The problems in each dimension being uncoupled, the method involves only 1D meshes and 1D problems. An algorithm that builds succe...
متن کاملProcessing Digital Image for Measurement of Crack Dimensions in Concrete
The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
