This is blinking frequency, so it will be harder ? They are not moving really fast, like 5cm in one second. Thank you for your answer.

Thanks you for your answer. Yes exactly, I need to detect the frequency of the PWM of my LED. So, what I need is calculate the numbers of frame when the LED are ON and the numbers of frame when the LED are OFF ?

My camera detects perfectly when the LED blink for low frequency, there is no problem for this. But what library should I use to track my LED when they are moving ? I have seen some projects and videos where the camera can follow easily the moving of the LED. But they don't explain how they do it and what code they wrote.

I'm a french studend but I'm actually working for a company in the UK which have no link with my university that's why I asked for code. My mistake, I understand the confusion. Thanks you for your quick answer.

Hello everybody,

First of all, i would like to say that i'm new on OpenCV so please don't laugh at me, and I'm sorry for my english I'm a french student..

In my project, I have got 3 circles of 7 LED which are moving. I have got a camera above them and each circle are blinking at differents frequency ( so 3 differents frequencies). I would like to track each circle and then recognize their frequency.

I'm using Community Core Vision as software, so I already detect blobs. But I would like to ignore all the others noise around it and then track only the LED. That's means, if something is moving next to the LED it needs to be ignore.

I checked on internet and I readed that is easy to detect LED and ignore the others object by using a filter with the frequency that I want to detect.

Is that true ? And if so, do you have any advices for my project ? What library should I use ? And if there a program which already exist for this ?

Thanks you for you answer and please feel free to comment.
