Abstract

Un método para obtener e insertar en tiempo real un objeto virtual dentro de una escena virtual a partir de un objeto físico, incluyendo realizar dinámicamente las acciones siguientes: - capturar a partir de una cámara física una imagen de un objeto físico contra un fondo; - extraer una silueta de dicho objeto físico de la imagen capturada y mapear la imagen capturada sobre una geometría tridimensional obteniendo un objeto virtual; - incorporar dicho objeto virtual como un elemento más en la escena virtual; y - orientar dicho objeto virtual con respecto a una cámara virtual con el fin de evitar que dicho objeto virtual se presente de canto, caracterizado porque el método incluye además: - obtener y usar parámetros intrínsecos y extrínsecos de dicha cámara física y dicha imagen capturada del objeto físico para calcular una posición de dicho objeto físico, y determinar una posición de dicho objeto virtual calculando al menos las coordenadas del punto más bajo de dicha imagen capturada de dicho objeto físico contra dicho fondo; - colocar el objeto virtual en dicha posición calculada de dicho objeto físico dentro de la escena virtual y seleccionar un eje de rotación para orientar el objeto virtual con respecto a la cámara virtual en base a dicha posición calculada del objeto físico; y - proyectar de nuevo dicha imagen capturada sobre la geometría tridimensional usando dichos parámetros intrínsecos y extrínsecos de cámara física.
