eyePIV is a bit of a revolution in the particle image velocimetry (PIV) world. Within eyeMOTION, the eyePIV plugin allows, from flow images, to calculate 2D2C velocity fields instantly in real time or in post-processing! Its revolutionary approach is to use an optimized optical flow algorithm embedded on a graphic board (GPU). Calculation times are thus drastically reduced, while obtaining highly accurate results.
Description
In addition to the considerable gain in terms of spatial resolution (one vector per pixel, no diffusion at small scales, no generation of false vectors), eyePIV offers greater flexibility of use: resolution of greater speed gradients, low image noise dependence, intuitive adjustment of parameters. Our development know-how can even make it possible to output the desired quantities in real time or in instant post-processing. Storage requirements, and therefore energy, are greatly reduced, and the duration of your films can be extended (> 1h)!
