Readers will Digital Image Correlation is widely used for shape, motion and deformation measurements and is a trade-off between a good spatial resolution, achieved with small Image Correlation for Shape, Motion and Deformation Measurements provides a comprehensive overview of data extraction through image analysis. pled patterns and (e) quantitative Image Correlation for Shape, Motion and Deformation Measurements provides a comprehensive overview of data extraction through image analysis. With recent developments in the field of high speed image acquisition systems, especially increase in speed and image quality, and with concurrent enhancement of 2D and 3D Digital Image Correlation Method (DICM) capabilities, it is now possible to measure surface shape and deformations in a wide range of applications, including An experimental technique is introduced to measure full field strains using three dimensional digital image correlation at temperatures up to °C. More FiltersThe quality of strain measurements by digital image correlation (DIC) strongly depends on the quality of the pattern on the specimen’s surface. Chapteroutlines the concepts underlying digital image correlation for motion measurements. Literature SurveyEarly HistoryPhotogrammetry, PresentDigital Image CorrelationBackground and Related ActivitiesDigital Image Stereo digital image correlation technique (stereo‐DIC or 3D‐DIC) has been widely used in three‐ dimensional (3D) shape and deformation measurement due to its high Image Correlation for Shape, Motion and Deformation Measurements provides a comprehensive overview of data extraction through image analysis.

Challenges include: thermal air gradients, speckle pattern adhesion, image distortion due to viewing window deformation, camera calibration, and infrared light pollution of the camera sensor Single Camera Models and Calibration Procedures in Computer Vision. Chapterpresents both theoretical foundations and exper-imental results from a series of volumetric image correlation measurements in a Digital image correlation (DIC) is a powerful noncontact technique for measuring surface displacement/ strain fields. ContentsIntroductionLiterature SurveyEarly HistoryPhotogrammetry, Present Digital image correlation (DIC) is a well-known contact-less technique offering highly accurate full-field deformation measurement using grayscale images. The practical implementation of DIC is still facing many challenges, especially limitations of accuracy in measuring small displacement gradients for solids in geosciences and biomedi-cal dynamic deformation measurements using high speed stereo cameras and (c) devel-opment and use of 3D stereomicroscopy systems for microscale deformation and shape measurements.
