Abstract:

A light flow deformation displacement measurement algorithm  based on a pyramid LucasKanade tracking technology was proposed. After the angular points of the image before the deformation were detected,  then the pyramid LucasKanade algorithm was used to search the matching points in the deformation image, and finally the deformation displacement value was calculated. The experimental results show that this algorithm has a high precision and good stability.
