Sub-pixel Precision Image Matching for Displacement Measurement of Mass Movements Using Normalised Cross-correlation
This study evaluates the performance of two fundamentally different approaches to achieve sub-pixel precision of normalised crosscorrelation when measuring surface displacements on mass movements from repeat optical images. In the first approach, image intensities are interpolated to a desired sub-pixel resolution using a bi-cubic interpolation scheme prior to the actual displacement matching. ...
متن کاملMeasurement of Surface Displacement and Deformation of Mass Movements Using Least Squares Matching of Repeat High Resolution Satellite and Aerial Images
Displacement and deformation are fundamental measures of Earth surface mass movements such as glacier flow, rockglacier creep and rockslides. Ground-based methods of monitoring such mass movements can be costly, time consuming and limited in spatial and temporal coverage. Remote sensing techniques, here matching of repeat optical images, are increasingly used to obtain displacement and deformat...
متن کاملA Novel Sub-pixel Matching Algorithm Based on Phase Correlation Using Peak Calculation
The matching accuracy of homonymy points of stereo images is a key point in the development of photogrammetry, which influences the geometrical accuracy of the image products. This paper presents a novel sub-pixel matching method phase correlation using peak calculation to improve the matching accuracy. The peak theoretic centre that means to sub-pixel deviation can be acquired by Peak Calculat...
متن کاملSmall Baseline Stereo Matching Method based on Maximum Likelihood Estimation
A small baseline stereo matching method based on maximum like estimation is proposed. Firstly, the mixed window strategy is used to determine the matching window for each point in the reference image. Secondly, the normalized cross correlation function is employed to compute matching cost for possible matching points in the disparity range, then the “winner-take all” strategy is utilized to com...
متن کاملMinimum Mean Square Error Approach in Images Processing for Full-field Displacements and Deformation Measurements
Abstract: A vision system is applied to full-field displacements and deformation measurements in solid mechanics. A speckle like pattern is preliminary formed on the surface under investigation. To determine displacements field of one speckle image with respect to a reference speckle image, sub-images, referred to Zones Of Interest (ZOI) are considered. The field is obtained by matching a ZOI i...
