TRAFFIC LIGHT RECOGNITION SYSTEM AND METHOD
First Claim
1. ) A traffic light recognition system, comprising:
- a kernelization module configured to;
receive a sequence of frames captured by an imaging device; and
project the sequence of frames into a kernel space;
a binarization module configured to binarize, based on a dynamically determined threshold, the sequence of frames separated in the kernel space;
a decision tree module configured to identify a set of candidate blobs in the binarized sequence of frames based on a set of predefined features; and
a classification module configured to determine if the identified set of candidate blobs is a candidate for representing a traffic light.

Abstract
The present disclosure is directed to a traffic light recognition system and method for advanced driver assistance systems (ADAS) and robust to variations in illumination, partial occlusion, climate, shape and angle at which traffic light is viewed. The solution performs a real time recognition of traffic light by detecting the region of interest, where extracting the region of interest is achieved by projecting the sequence of frames into a kernel space, binarizing the linearly separated sequence of frames, identifying and classifying the region of interest as a candidate representative of traffic light. With the aforesaid combination of techniques used, traffic light can be conveniently recognized from amidst closely similar appearing objects such as vehicle headlights, tail or rear lights, lamp posts, reflections, street lights etc. with enhanced accuracy in real time.
