Abstract
existem vários tipos de dispositivos plenópticos e matrizes de câmeras disponíveis no mercado, e todos esses dispositivos de aquisição do campo de imagem possuem seu formato de arquivo proprietário. no entanto, não há padrão que suporte a aquisição e transmissão de informações multidimensionais. é interessante obter informação relacionada com uma correspondência entre pixels de um sensor do referido sistema de aquisição óptica e uma distância de objeto do referido sistema de aquisição óptica. de fato, saber qual parte do espaço de objeto de um sistema de aquisição óptica que um pixel pertencente ao sensor do referido sistema de aquisição óptico está detectando permite a melhoria das operações de processamento de sinal. a noção de feixe de pixels, que representa um volume ocupado por um conjunto de raios de luz em uma distância de objeto de um sistema óptico de uma câmera, juntamente com um formato compacto para armazenar essa informação, é assim introduzida.
