This package is designed to perform digital image correlation on large images (70,000 x 70,000 px has been tested) using chunking and GPU acceleration. Using the GPU, DIC correlation from a sub-window of 2048x2048 to 16x16 with no overlap on a (16,000 x 16,000 px) px image takes around one minute. To compute strain fields and perform advanced analysis of the displacement field, see DefDAP.

Download the package and run
pip install -e .
OR
pip install git+https://github.com/MechMicroMan/openpiv-python.git
Note: you will need a Nvidia GPU which supports CUDA 12x to use GPU acceleration
