Abstract

trata-se de um sistema de câmeras que é configurado para capturar, através de uma pluralidade de câmeras, informações de imagem em 360 graus de uma área local, da qual pelo menos uma porção está em estéreo. o sistema de câmeras determina respectivas configurações de exposição para a pluralidade de câmeras. uma velocidade de obturador mínima e uma velocidade de obturador máxima são determinadas a partir das configurações de exposição determinadas. um conjunto de configurações de exposição de teste é determinado com o uso da velocidade de obturador mínima e da velocidade de obturador máxima determinadas. um conjunto de imagens de teste é capturado com o uso da pluralidade de câmeras em cada configuração de exposição de teste no conjunto de configurações de exposição de teste. cada conjunto de imagens de teste inclui imagens de cada uma dentre a pluralidade de câmeras que são capturadas com o uso de uma mesma respectiva configuração de exposição de teste. uma configuração de exposição global é selecionada com base nos conjuntos capturados de imagens de teste. a configuração de exposição global selecionada é aplicada à pluralidade de câmeras.
