AI PIV

Artificial Intelligence (AI) PIV is the newest unique innovation from Microvec. With the advances of artificial intelligence and ever wider adoption of deep learning techniques based on Convolutional Neural Network (CNN), common in the computer and machine vision worlds in recent years, PIV methodology based on deep learning has turned out to be very accurate. Microvec’ AI PIV is based on the optical flow neural network which has already proven itself in the computer vision community. It has been successfully applied to fluid mechanics and particle image velocimetry, where global and quantitative velocity field from images can be extracted with improved computational efficiency without reduction of accuracy.

3D PIV

3D PIV system is based on the original 2D PIV system but uses the principle of stereoscopic imaging to add the third dimension. At least two sets of cameras view the test area from different angles and with the two sets of two-dimensional velocity vector components a third velocity vector component can be calculated within the test area. The image is first calibrated, and afterward this third velocity component can be evaluated.
