Abstract:
Methods, systems, and techniques for validating road intersections are presented. The method includes receiving annotated intersection data that, for each lane of a particular candidate intersection, indicates one or more attributes of the lane; processing the annotated intersection data to generate an intersection fingerprint for the particular candidate intersection that is sensitive to a topological structure of the lanes of the particular candidate intersection and is invariant to a geometry of the lanes of the particular candidate intersection; designating the particular candidate intersection as validated without performing the one or more quality control processes based at least on the intersection fingerprint; and storing a representation of the particular candidate intersection in the roadgraph.
