Localization using path-specific trackers for autonomous or semi-autonomous systems and applications

Abstract

In various examples, path-specific trackers may be initialized and used to localize a machine (e.g., an autonomous or semi-autonomous machine or vehicle) with respect to a specific path in an environment. For instance, when the machine passes through a junction of multiple road segments, a respective tracker may be initialized for each road segment, and the trackers may be placed at respective candidate locations along each of the road segments. The candidate locations may represent possible locations of the machine along the road segments. Using various input data, a determination may be made regarding which tracker—or candidate location—most closely corresponds to the actual location of the machine subsequent to the junction. In some examples, the tracker may be selected for tracking the location of the machine along the current road segment while the other trackers may be terminated or otherwise removed.
