MATLAB Functions for RoadRunner HD Maps

R2026b

Create, edit, query, and convert HD maps in RoadRunner using MATLAB^®

RoadRunner provides MATLAB functions to convert custom data into the RoadRunner HD Map data model and import your data into RoadRunner. Using these functions, you can create a new map, edit an existing map, and read from and write to a file. You can also represent lanes, lane boundaries, lane markings, junctions, barriers, and signs in the HD Map. You can query an HD Map and retrieve information about the current lane, neighboring lanes, road geometry, and projection point on the centerline of a lane at a specified actor pose within the HD Map.
