US 2026/0092787 A1 · ASSOCIATING PERCEIVED LANES WITH MAPPED ROADWAYS FOR AUTONOMOUS OR SEMI-AUTONOMOUS SYSTEMS AND APPLICATIONS

Abstract

In various examples, junction points corresponding to locations where disparate lanes deviate from one another may be determined and used to associate (e.g., match) perceived lanes with corresponding, mapped road segments. For instance, the systems and methods of the present disclosure may use perception data to determine locations of junction points where two or more lanes deviate from one another, as well as to determine lateral distances between adjacent lanes. Using the junction points and/or the lateral distances, the lanes may be sorted into various lane groups, where each lane group may correspond to a different road segment. In some examples, the systems may match individual lanes or lane groups to respective road segments of a map based on the junction points corresponding to mapped road junctions and/or lane geometry corresponding to mapped road topology.

Dependent claims

A method comprising:

determining, using perception data and based at least on a lateral distance between one or more first lanes and one or more second lanes, one or more first locations in an environment that correspond to one or more first junction points at which the one or more first lanes deviate from the one or more second lanes;
determining, based at least on map data representing a map of the environment, one or more second locations in the environment that correspond to one or more second junction points at which one or more first road segments deviate from one or more second road segments;
associating, using at least the one or more first locations and the one or more second locations, the one or more first lanes with the one or more first road segments and the one or more second lanes with the one or more second road segments;
and
performing one or more operations associated with a machine in the environment based at least on the associating.
