Abstract
The paper investigates temporal semantic stability in UAV perception by associating frame-wise predictions with world-space locations through metric 3D fusion.
Reality Card
Core Claim
The study reveals that high aggregate world-space agreement can misrepresent temporal stability due to limited repeated-observation support.
Method / Result
The introduction of a voxel-level evaluation framework that characterizes Semantic Belief Drift (SBD), Observation Persistence (OP), and semantic uncertainty.
Limitations
The findings indicate that conditions reducing world-space recurrence can artificially inflate perceived stability, complicating reproducibility.
