Abstract
A traffic signal display estimation system recognizes, based on the position information of a vehicle and a traffic signal information, a traffic signal included in a camera image, identifies a traffic signal display for each recognized traffic signal, and calculates, for each traffic signal, a first evaluation value indicating the certainty of the identified traffic signal display. The system integrates, based on a traffic-signal-to-traffic-signal relational information, a forward traffic signal that is ahead of the travelling direction and that the vehicle should follow and a traffic signal correlated with the forward traffic signal in terms of the traffic signal display, among a plurality of recognized traffic signals. When there is an inconsistency in traffic signal displays identified between a plurality of integrated traffic signals, the system determines a first estimated traffic signal display of the forward traffic signal, based on the first evaluation value for each traffic signal.
