20230274523 · 2023-08-31 ·

Embodiments are directed to the association of concurrent tracks using graph crossings. Signal beams may be employed to scan paths across an object such that sensors separately detect signals from the signal beams reflected by the object. Crossing points may be determined based on a plurality of trajectories that intersect each other during the scan of the object. Graphs may be generated based on the portion of trajectories and the crossing points such that each edge in the graphs corresponds to a crossing point and such that each node in the one or more graphs corresponds to a trajectory. The graphs may be compared to determine one or more matched graphs that may share a common topology. Common trajectories may be determined based on the matched graphs such that each common trajectory may be associated with a same path across the object and a separate sensor.
