Abstract

La descripción temática se enfoca hacia el uso de un patrón de proyección conocido para robustecer la detección de profundidad estéreo (u otra basada en cámaras). Se detectan puntos en las imágenes capturadas y se comparan con el patrón de proyección conocido a diferentes profundidades, para determinar una puntuación de confianza de pareo en cada profundidad. Las puntuaciones de confianza se pueden utilizar como base para determinar una profundidad en cada ubicación de punto, que puede estar en la resolución de sub-pixel. Las puntuaciones de confianza también pueden utilizarse como base para ponderar o balancear la interpolación de la profundidad de pixeles para encontrar valores de profundidad para los pixeles que están entre los pixeles que corresponden a las ubicaciones de los puntos.
