Include ball in radar view?

[gdubya]

Great project! Thanks for sharing. I hope to test it out more extensively in the near future.

Is it possible to include the ball position in the radar view? That would give a bit more context to the player movements.

Hi @gdubya 👋🏻 yup, I will probably include it in the radar view.

@SkalskiP Note that including the ball into the radar view is tricky as it is not always on the ground and hence its location will be wrong for flying balls. Any ideas how to tackle this issue?

Hi @druefena 👋🏻, for now, I was just thinking about doing it in a naive way. But you're absolutely right. Do you have any ideas on how to tackle this problem?

@SkalskiP Watching the circles that represent the ball position over time, you can often see the parabolic trajectory. Perhaps there is a way to look at this history to determine if the ball was in the air. It would likely need to be done as a post processing step as you would need to get the ball path coord history first and then to try and estimate the height... seems a bit complex though as the camera is often moving as the ball is!

Btw, thanks for posting this repo, you've combined a lot of separate concepts into a really useful and practical repo. I'm learning a lot from it :)

@fenaux, your work on that is precious; thanks a lot! But I have an issue: the ball is poorly detected in front of the stands. So, the parabolic trajectory is uncompleted. Do you have the same problem?

@clairesecehDS on which video ? Due to the fact missing detections are replaced by a linear interpolation, if that happens during a parabola, this will lead to false linear segment or false acceleration peak. If you wish to submit a video please provide a link in my repo. Thanks for your interest.
