20230154073 · 2023-05-18 ·

System and methods are disclosed for providing efficient rendering of map data. Instead of providing a set of points that describe a geographic feature, e.g., systems and methods provide spline functions that allow a device to generate smooth and accurate overlays of the geographic feature on the fly without additional information, for example, when changing a zoom or scale level.

Lane mapping and localization using periodically-updated anchor frames
11651598 · 2023-05-16 · ·

A hybrid approach for using reference frames is presented in which a series of anchor frames is used, effectively resetting a global frame upon a trigger event. With each new anchor frame, parameter values for lane boundary estimates (known as lane boundary states) can be recalculated with respect to the new anchor frame. Triggering events may a based on a length of time, distance traveled, and/or an uncertainty value.

Service area maps for autonomous vehicles

Aspects of the disclosure provide for the generation of a service area map for autonomous vehicles. For instance, graph nodes of a road network may be iterated through in order to identify a set of reachable graph nodes based on a set of routing parameters that define driving limits for the autonomous vehicles. The road network may include the graph nodes as well as edges connecting ones of the graph nodes. A set of S2 cells may be identified based on the set of reachable graph nodes. Vertices of each S2 cell of the set of S2 cells may be determined based on whether each S2 cell of the set of S2 cells is occupied by any of the graph nodes of the set of reachable graph nodes. Contours through cells may be drawn based on the scores. The service area map may be generated using the contours.
