Systems and methods for rear signal identification using machine learning
First Claim
1. A signal identification system for identifying rear indicators of a nearby vehicle, comprising:
- one or more processors;
a memory communicably coupled to the one or more processors and storing;
a monitoring module including instructions that when executed by the one or more processors cause the one or more processors to, in response to detecting the nearby vehicle, capturing signal images of a rear portion of the nearby vehicle; and
an indicator module including instructions that when executed by the one or more processors cause the one or more processors to;
i) compute a braking state for brake lights of the nearby vehicle that indicates whether the brake lights are presently active by analyzing the signal images according to a brake classifier, andii) compute a turn state for rear turn signals of the nearby vehicle that indicates which of the rear turn signals are presently active by analyzing regions of interest from the signal images according to a turn classifier,wherein the brake classifier and the turn classifier are each comprised of a combined network architecture including both a convolutional neural network (CNN) and a long short-term memory recurrent neural network (LSTM-RNN) configured in series with the LSTM-RNN accepting an input that is a final output of the CNN, andwherein the indicator module includes instructions to provide electronic outputs identifying the braking state and the turn state and to control one or more vehicle systems of a host vehicle in response to the electronic outputs.

Abstract
System, methods, and other embodiments described herein relate to identifying rear indicators of a nearby vehicle. In one embodiment, a method includes, in response to detecting a nearby vehicle, capturing signal images of a rear portion of the nearby vehicle. The method includes computing a braking state for brake lights of the nearby vehicle that indicates whether the brake lights are presently active by analyzing the signal images according to a brake classifier. The method includes computing a turn state for rear turn signals of the nearby vehicle that indicates which of the turn signals are presently active by analyzing regions of interest from the signal images according to a turn classifier. The brake classifier and the turn classifier are comprised of a convolutional neural network and a long short-term memory recurrent neural network (LSTM-RNN). The method includes providing electronic outputs identifying the braking state and the turn state.
