Abstract

In this paper we describe an audience voting system which can be used for all kinds of judged sport events like diving, synchronised swimming, gymnastics, and ice-skating.
The basis of the system is cameras, which are fixed to the ceiling. Each camera can cover approximately 1000 spectators of the audience.
The image processing software recognises the judging, displayed by boards from every individual spectator.
The cost of the solution is quite low, because we need less than 20 cameras for an audience of up to 15,000 spectators and you can use them for surveillance purposes, too.
