    This is a new module in my Tennis Toolkit app. With this you can check the height of a tennis net (supposed to be 36") without having a tape measure.

    Doing a few things I had not done before which made it fun:
    Making draggable controls on an otherwise empty panel.
    Using the camera preview and saving the preview image.
    Having some "magnified" preview panels to help the user fine tune the position.

    It's accurate if the instructions are followed, i.e. configuring the height you are holding the camera at.....but not as accurate as a tape measure.

    On to the next thing.

    Very nice. Do you have some code you can share on how you:

    Making draggable controls on an otherwise empty panel.
    Using the camera preview and saving the preview image.
    Having some "magnified" preview panels to help the user fine tune the position.

    Thanks.

    Idea: Attach a phone to the net, and use accelerometer sensor to detect if the ball touched the net. One less referee needed.

    ...and protect it with a thick bubble wrap :D

    You can probably put it in a box on the pole the net is attached to and still get accurate enough data.

    Nothing packaged, I think without the whole thing it would not be very clear.

    I've considered that but to be honest "lets" (where the serve strikes the net cord but still falls into play) are pretty easy to detect an not really a problem.
