METHODS, SYSTEMS, AND COMPUTER-READABLE STORAGE MEDIUMS FOR DETECTING STATE OF SIGNAL LIGHT

Some embodiments of the present disclosure provide methods, devices, computer-readable storage mediums for detecting a signal light. The method may include obtaining a first image and a second image previous to the first image in time sequence, wherein both the first image and the second image include a same target signal light; determining, based on the first image, a first state of the target signal light in the first image; determining, based on the second image and the first image, a second state of the target signal light in the first image; and determining, based on the first state and the second state, a target state of the target signal light at a time point when the first image is captured.
