Abstract

aparelho e método para avaliar uma qualidade de captura de imagem de uma cena. um aparelho para avaliar uma qualidade para captura de imagem compreende um armazenamento (101) para armazenar um modelo de uma cena e um circuito de captura (105) para gerar imagens virtuais capturadas para uma configuração de câmera mediante a renderização do modelo. um circuito de geração de profundidade (107) gera dados de profundidade de modelo a partir do modelo e um circuito de estimativa de profundidade (111) gera dados de profundidade estimados a partir das imagens virtuais capturadas. um primeiro circuito de síntese (109) e um segundo circuito de síntese (113) geram uma primeira e uma segunda imagens de visão para poses de teste mediante o processamento das imagens virtuais capturadas com base nos dados de profundidade de modelo ou nos dados de profundidade estimados, respectivamente. um circuito de referência (103) gera imagens de referência para as poses de teste mediante a renderização com base no modelo. um circuito de qualidade (115) gera uma métrica de qualidade com base em uma comparação entre as primeiras imagens de visão, as segundas imagens de visão e as imagens de referência.
