GeoPIV-RG is a free image analysis module for MATLAB designed for geotechnical and structural engineering research applications. It is capable of sub-pixel measurement resolution for problems involving large displacements and deformations.

The module features include:

  • Bi-quintic B-spline image intensity interpolation
  • First order subset deformation
  • Reliability Guided (RG) computation scheme
  • Automatic large deformation reference image updating scheme
  • Photogrammetric correction sub-routines
  • Rotating reference frame strain sub-routine
  • Plotting sub-routines

All files run directly from the Matlab command line and have been designed for efficient batch processing of image data.
