Abstract

"PROCESSO DE AQUISIçãO DE IMAGENS DE VìDEO E SISTEMA DE VìDEO AUTO-ESTEREOSCóPICO". A invenção se refere a um processo de aquisição de imagens de vídeo auto-estereocópicas simuladas de uma cena a visualizar. Ele utiliza, a partir de dados memorizados que possuem informações em três dimensões n(com n<242>3) câmeras simuladas que geram cada uma delas uma imagem de uma cena de acordo com um eixo ótico dado. Os eixos óticos das câmeras simuladas são convergentes em um ponto situado a uma mesma distância D das câmeras simuladas. A cena a visualizar apresenta um ponto mais próximo P~ p~ e um ponto mais afastado P~ e~, e escolhe-se por um lado a distância D~ min~ entre as câmeras simuladas e o ponto mais próximo P~ p~, e por outro lado a distância inter-câmeras (<MU>b<MV>) de tal modo que, para um focalização que varia entre o ponto mais próximo P~ p~ e o ponto mais afastado P~ e~, o ângulo 2<244> entre os ditos eixos de duas câmeras simuladas adjacentes varia entre um valor no máximo igual a 4,5° para o ponto P~ p~ e um valor pelo menos igual a 0,2° para o ponto P~ e~.
