BatonTrack1.0: A Benchmark for Multi-Object Tracking Based on Multi-Satellite Cooperative Observation

Each video segment lasts approximately 14 s and has a frame rate of 5 frames per second (fps). Since the satellite overpasses are not temporally contiguous, adjacent video segments contain observation gaps ranging from approximately 1 min 44 s to 2 min 1 s. To preserve the continuity of object motion across successive satellite observations, we construct cross-satellite multi-object tracking sequences by dynamically cropping each segment according to the locations of the objects, rather than extracting the same fixed geographic area across all segments.

Each sequence is annotated with both standard multi-object tracking labels and cross-segment spatiotemporal annotations, including object locations, identity labels, frame timestamps, and inter-segment projection transformations. Overall, BatonTrack1.0 contains 8 multi-object tracking sequences with annotations for 192 aircraft targets, covering typical operational states such as takeoff, landing and taxiing.It provides a standardized foundation to develop, validate, and compare advanced algorithms capable of preserving object identities across spatial-temporal gaps.
