Abstract

De acuerdo con una modalidad, un sistema para determinar una posición de un vehículo incluye un sensor de imagen, un componente de vista descendente, un componente de comparación y un componente de ubicación. El sensor de imagen obtiene una imagen de un entorno cerca de un vehículo. El componente de vista descendente se configura para generar una vista descendente de una superficie del suelo con base en la imagen del entorno. El componente de comparación se configura para comparar la imagen de vista descendente con un mapa, el mapa comprende un mapa de intensidad de luz descendente LIDAR o un mapa semántico basado en vectores. El componente de ubicación se configura para determinar una ubicación del vehículo en el mapa con base en la comparación.
