Abstract
A disambiguation system for an autonomous vehicle is described herein that disambiguates a traffic light framed by a plurality of regions of interest. The autonomous vehicle includes a localization system that defines the plurality of regions of interest around traffic lights captured in a sensor signal and provides an input to a disambiguation system. When the captured traffic lights are in close proximity, the plurality of regions of interest overlap each other such that a traffic light disposed in the overlapping region is ambiguous to an object detector because it is framed by more than one region of interest. A disambiguation system associates the traffic light with the correct region of interest to disambiguate a relationship thereof and generates a disambiguated directive for controlling the autonomous vehicle. Disambiguation can be achieved according to any of an edge-based technique, a vertex-based technique, and a region of interest distance-based technique.
