Link object tracks across two perception systems

0
Remix

Two perception systems, A and B, track the same objects around a vehicle independently, each with its own IDs, and each emits observations of its tracks over time. Implement an ObjectTracker that:

  1. records that an A ID and a B ID refer to the same physical object,
  2. accepts observations from either system, and
  3. returns the merged history of a physical object, given either system's ID.

Discuss links that arrive after observations, chains of links, and how you would handle a link that turns out to be wrong.
