Abstract
An algorithm is proposed for processing phase images with the use of computing power of graphics processing units (GPUs) for three-dimensional geometry measurements by means of phase triangulation. It is shown that implementation of the phase image decryption algorithm on the GPU is faster by more than 100 times than on the central processing unit (CPU). Practical implementation of the proposed approach can substantially improve the performance of phase triangulation methods.
