Could also use a microphone count the number of times the rope hits the floor but your approach Bruno would be more exact.

Fair point lok1950, but is the OP more interested in the goal or the method by which it is achieved? S/he might be mentioning the camera simply because that is what is to hand.

Yes! I think it's eminently possible.

I think you should check out OpenCV -

And try looking for some similar vids on u-toob.

I'd be interested to see what happens!

I think this would be difficult (but not impossible) to do on a computer with images captured by a camera. You could try a kinect (if that is the word) but you'd similarly have quite a programming overhead. Although, as an aside, I'd have a look and see if someone has written a library for counting events that occur in images/a video stream.

And lots of money for the cameras and programmers as there no off the shelve app available

In theory: yes. In practice: only if you have a lot of time on your hands and not a life to live

Hi

Is it possible to use a webcam to count how many jumps I do while skip roping.

And displaying the number live on a screen!

Kind regards Thusgaard
