| Abstract: |
Intensity Integration Technique (IIT) is an image correlation technique founded on energy conservation principle to contour reflective surfaces. The sum (integral) of intensities along pixel lines is identified as correlation parameter between the loaded and the unloaded images. At present, this procedure is employed to contour 2D reflective plates aided by projected gridlines onto reflected intensity images. Here, the gridline projection is dispensed with thereby simplifying the experimental procedure, with an iterative algorithm, Iterative Intensity Integration Technique (IIIT), developed to contour deformed reflective plates. In illustration, centrally as well as eccentrically loaded circular plates are studied. As a viable extension of IIIT, a method is suggested for generating digital Moiré fringes with pixel lines as grating lines. [ABSTRACT FROM AUTHOR] |
