Abstract

geração de imagens de profundidade de tempo de vôo de alta resolução. são fornecidos técnicas e sistemas para gerar imagens de profundidade de tempo de voo (tof) de alta resolução. em alguns exemplos, um aparelho inclui um sistema de projeção incluindo um ou mais dispositivos emissores de luz, cada dispositivo emissor de luz sendo configurado para iluminar pelo menos uma porção de um campo de visão (fov) inteiro do sistema de projeção. o fov inteiro inclui uma pluralidade de porções de fov. o aparelho inclui também um sistema de recepção incluindo um sensor configurado para capturar sequencialmente uma pluralidade de imagens com base em uma pluralidade de reflexões de iluminação correspondentes à luz emitida pelo um ou mais dispositivos emissores de luz. cada imagem da pluralidade de imagens corresponde a uma dentre a pluralidade de porções de fov. uma resolução de imagem associada a cada imagem corresponde a uma resolução total do sensor. o aparelho inclui adicionalmente um processador configurado para gerar, utilizando a pluralidade de imagens, um mapa de profundidade de resolução aumentada associado ao fov inteiro.
