Abstract
Zájmové objekty jsou snímány v prostoru a podle jejich prostorových souřadnic se přiřazuje vytvářeným tónům výška, barva a hlasitost. Souřadnice objektu se při tom určí na principu strojového vidění kamerového systému. Kamera (1) snímá scénu, ve které se vyskytují zájmové objekty (2), které jsou odlišné od okolního prostředí. Každý jednotlivý snímek je předzpracován tak, že dojde k segmentaci obrazu na základě výskytu dané barvy, která je dána uživatelským nastavením jednotlivých barevných souřadnic. U každého zájmového objektu jsou stanoveny jeho momentové charakteristiky, ze kterých se určí plocha zájmového objektu v obrazu a dvě prostorové souřadnice těžiště. Třetí prostorová souřadnice těžiště objektu se v případě snímání jednou kamerou určí po počáteční kalibraci podle velikosti plochy zájmového objektu v obraze, v případě snímání alespoň dvěma kamerami se určí na základě superpozice snímků různých kamer snímaných ve stejném časovém okamžiku.
