Abstract

Un sistema y método para estimar el espacio libre y asignar probabilidades de espacio libre en datos de nube de puntos asociados con un vehículo autónomo que viaja en una superficie, que incluye tomar en cuenta el ruido de sensor, la disponibilidad del sensor, las alturas de los obstáculos, y la distancia de los obstáculos del sensor; el sistema y método pueden incluir determinar planos de superficie y clasificar puntos de nube de puntos según si los puntos caen o no en planos de superficie, entre otros factores.
