Abstract

En una modalidad, un método incluye recibir una imagen generada por una cámara asociada con un vehículo. La imagen incluye un punto de interés (POI) asociado a un objeto físico. El método también incluye la determinación de un número de pixeles desde el POI de la imagen hasta un borde de la imagen. El borde de la imagen representa una ubicación de la cámara. El método incluye, además, la determinación de una distancia de desplazamiento desde el POI hasta una unidad del sistema de posicionamiento global (GPS) asociada al vehículo utilizando el número de pixeles.
