Microvec Presents New AI PIV Software

MUNICH – Microvec, one of the leaders in the field of fluid mechanics, is presenting the newest Artificial Intelligence Particle Image Velocimetry (AI PIV) software at the 13th International Symposium on Particle Image Velocimetry, which is taking place from July 22 to 24 in Munich, Germany. This is the first software of its kind in the world and Microvec is once again introducing unique and innovative product in the field of Particle Image Velocimetry.

Based on deep learning technique called Convolutional Neural Network (CNN), commonly used in computer vision systems, Microvec applied it to fluid mechanics and particle image velocimetry. Microvec AI PIV is based on the optical flow neural network where global and quantitative velocity field from images can be extracted with improved computational efficiency without reduction of accuracy.

It is the world’s first implementation of AI in PIV. The experimental results indicate that compared with the traditional cross correlation and optical flow methods, the proposed deep neural network has advantages in accuracy.

AI-PIV calculation time faster than traditional PIV “Microvec AI PIV software has several advantages,” said Dr. Runjie Wei, CTO of Microvec “The accuracy of results extends to single-pixel calculations, since the output velocity field has displacement vectors at every pixel. The calculation time is faster than traditional PIV calculation time when using GPU and the calculations speed is near real time. Dense velocity field is obtained much faster. AI PIV represents continuing investment in innovative and unique new technologies.”
