This is a really cool project.

Could the club recreate the effect from this video?

I used optical flow to track two black spots on the club. The color of the line connecting them depends on the slope. If the club is balanced, the line is blue. As the club falls out of balance, the line fades to red.

Code used to create balance effect using optical flow in Python.

Hi,

I like what you do with opencv. I'd like to try, when I get some time.
Thank you for sharing your code !

Yeah I think it's possible and even more.
I haven't really yet the skill to talk about that, but I think you could also detect the trajectories, with the help of IMU and Kalman filter. And therefore also detect siteswap in real time (or do anything else). But there is much math for me.
Also, I had an idea that might be simplified ?
If we draw trajectories in a pictures, with the add of temporal dimension for throws and catch.
May be we can detect the sitswap with opencv by comparing with a database pictures.
I know that a matematician will do better. But still can be a way ? not sure, just an idea.

For now I can't soldering IMU because of my footprint on the PCB. But I will soon have the new version, and I hope it'll do !
The driver are not yet finished.

When everything will be in place, I hope mathema/Juggler come play with !

Thanks for your interest.

Laurent

I look forward to seeing more of this. Please keep me updated by posting in the Logs section of the Juggling Edge. If you get any data, I would love to see it.

If you have any juggling related ideas for OpenCV, please share those as well.
