Claim 16:
17. A system for training a classifier to identify traffic signal states in images, the system comprising:
a processor and
programming instructions that are configured to cause the processor to:
access a data store that contains digital images of an environment along with, for each of the images, a time of capture,
process a group of the digital images identify an image that includes a traffic signal, determine the time of capture of the identified image,
receive signal data, from a roadside unit, that indicates signal phase and timing of the traffic signal at the time of capture of the identified image from an external source,
analyze the signal data received at the time of capture of the identified image to determine a state of the traffic signal at the time of capture of the identified image,
label the identified image with a label of determined state, and
pass the identified image and the label to a classifier of an autonomous vehicle to train the classifier.
