Abstract

MÉTODO E SISTEMA PARA GUIAR UM VEÍCULO. Um método e sistema para guiar um veículo inclui um receptor determinador de localização (28) para coletar dados de localização para o veículo. Um módulo de visão (22) coleta dados de visão para o veículo. Um estimador de qualidade de localização (24) estima os dados de qualidade de localização para os dados de localização durante uma janela de tempo de avaliação. Um módulo de visão (22) estima dados de qualidade de visão durante a janela de tempo de avaliação. Um supervisor (10) seleciona pelo menos um de um peso de dados de localização e um peso de dados de visão baseado nos dados de qualidade.
