Video: WORLD’S HARDEST FLOORBALL SHOT (205.0 km/h) – measured and filmed (HD) with Nokia N8! Available at the Ovi Store

Here’s a somewhat witchcrafty app that you may have come across before called Speed Hero – a Sports Radar application that can help you measure the speed of your ball shots from football to floorball. There’s an actual speed gun there with the Nokia N8 and they’re both reporting identical/similar speeds. This is not like your GPS based speed sensor. The N8 is static and somehow calculates the speed of moving objects around it.

To try the app yourself it’s available at the Ovi Store 🙂

From the description:

The Finnish National Floorball Team player Otto Tikka shot a new world record 205.0 km/h. The record was measured with Speedhero Magical Games App using Nokia N8 and Stalker Sport speed radar gun. The record was made during the Finnish National Floorball Team training camp on 3 Nov 2010.

How does it work? In the comments SpeedHero team answers:

The measuring of the top speed is based on advanced sound recognition technology using the microphone of your mobile phone. Speedhero uses sophisticated algorithms to detect the first impact sound (your contact with the ball) and the second impact sound (the ball’s impact on the wall). Then, using a tested sport specific flight time dynamic formula and the processing power of your mobile phone, Speedhero instantly calculates the top speed of the ball.

    That is pretty cool. However it really need a quiet place with a wall for stuff to bounce off!

    It would be interesting if you could work it out using the camera instead? we do get high resolution shots (25 of the them per second) it could be possible to spot a ball at starting point and then a few frames later and work out how far it has gone.

      it wouldn’t work with the camera, a normal “high speed” camera captures at 1000+ frames per second, the 25 frames per second would see nothing!

        not true all you need is an algorithm that would be able to give you the speed based on how much the ball traveled between 2 frames , it wont be that accurate but would still be “good enough”

        I was thinking if you make an app that would know the default size of some objects, let start with a basketball.

        Then you take the first frame of the video work out the angular size.Thus know how far you are from it.

        Again do the same thing a few frames later, use angular size and get a new distance. The distance change in those frames over the time will let you work out the speed.

        There is already face detecetion in the camera, so it would be possible to program it to detect other shapes.

        Because we have a high res video due to the bigger sensor it can still work with the object in the distance.

        Imagine an app where you record video, see the first frame, click on an object, the phone then skips a few frames then you click on the same object. based on the change in shape/size it can give you the speed.

    I have this app and it works well even if there is some noise around. There are really good options for senstivity…;)

    Magical?!

    Yeah! Magical. Camera would be great but you still need to know the top speed.. and for that you need sport specific flight time dynamic formula.
