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 کاملA three-frame digital image correlation (DIC) method for the measurement of small displacements and strains
Digital image correlation (DIC) has become a well-established approach for the calculation of full-field displacement and strains within the field of experimental mechanics. Since their introduction, DIC methods have been relying on only two images to measure the displacements and strains that materials undergo under load. It can be foreseen that the use of additional image information for the ...
متن کاملFundamentals of Three-dimensional Digital Image Processing
This book is a detailed description of the basics of 3-dimensional (3D) digital image processing, in particular the processing of images from techniques such as CT, MRI, and nuclear emission tomography. The book is based on 1980s research by the first author, Dr. Toriwaki, at Nagoya University and Chukyo University, Japan. The targeted audience is primarily graduate students and scientists in b...
متن کاملThree-Dimensional Image of A Communicating Uterus
Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
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...
