PIVlab v2.50 with parallel processing and camera / laser control released!...
At least for me, this is a great update as processing speed is improved quite a bit, and I can now capture image data and control our laser directly in PIVlab. Sooooo much easier to do experiments for...
View ArticleReal-time PIV in PIVlab!
Today, I quickly tested if I can do real-time particle image velocimetry in PIVlab, and it works :D. Data rate is about 3 Hz, but the code is not optimized yet and running on a core i5 laptop:
