Multi-sensor identity tracking with Event Graphs

Peter Morton, Bertrand Douillard, James Underwood

 
  • Segmented Velodyne scans[1] are tracked by associating centroids[2].
  • Identities of tracked objects become ambiguous after interactions.
  • An Event Graph [3] is built to model the interactions.
  • Appearance information (e.g. from camera) is used to resolve the ambiguity.
