Abstract
La divulgación se refiere a un dispositivo de reconstrucción de imágenes 3D (100) que incluye una cámara estéreo (105, 110), un dispositivo de almacenamiento de datos (130), y un módulo de reconstrucción 3D (150). La cámara estéreo (105, 110) incluye una primera cámara y una segunda cámara que toman un par de imágenes del objetivo en un ambiente bajo el agua. El dispositivo de almacenamiento de datos (130) almacena una pluralidad de conjuntos de parámetros, cada conjunto de la pluralidad de conjuntos de parámetros modelando la cámara estéreo que produce imágenes de un objetivo bajo el agua a una distancia de la cámara estéreo. La pluralidad de conjuntos de parámetros modela la cámara a diferencias distancias. El módulo de reconstrucción 3D (150) calcula una posición 3D del objetivo en base a una posición 2D del objetivo dentro del par de imágenes y un conjunto seleccionado, seleccionado a partir de la pluralidad de conjuntos de parámetros; Método.
