How to implement real time dense optical flow app with camera

Even I build a python opencv with cuda and gpu enable, the time the Jetson Nano cost to calculate the dense optical flow of two frames cost 3 seconds. Any suggestion about which API or SDK should I use to build a dense optical flow program that enable to calculate the flow in around 5 ~ 10 FPS on Jetson Nano?


You could give a try to VPI: VPI - Vision Programming Interface: Algorithms

I found a post here. Seems like it doesn’t support on Nano

Good to know, jet.code21. puffvayne, perhaps you could share your code to check if there are any parts where it can be optimized.
