1. A signal lamp recognition method, comprising:
recognizing a plurality of video frames by using a signal lamp recognition model to obtain state information of a real signal lamp and state information of a simulated signal lamp; and
determining a time delay between the real signal lamp and the simulated signal lamp according to the state information of the real signal lamp and the state information of the simulated signal lamp.
