1. A method for conveying data on a flying object in a scene, the method comprising:

  • (a) capturing a plurality of video frames of the scene by two or more video cameras to get several video frames each including image of the object;

    (b) identifying said object in captured video frames to get object parameters associated with said captured video frames;

    (c) calculating one or more motion variables of said object using said object parameters;

    (d) based on the calculated motion variables, solving motion equations for anticipated object trajectory taking into account at least one effect selected from the group of effects consisting of;

    (i) an effect of object collision with a ground surface;

    (ii) air friction;

    (iii) effect of wind on the object; and

    (iv) interaction of a spinning object with air;

    and(e) conveying data related to the anticipated object trajectory as calculated taking into account said at least one effect to one or more devices.
