real-scale

Definition

Represented at true physical dimensions rather than in arbitrary units. Reconstructions and simulators often get shape right while leaving scale unresolved, and real-scale means distances, speeds, and path lengths can be read as meters and seconds — which is what lets a policy trained there transfer to hardware. The claim is about metric correctness, not about the environment being large, though in urban settings the two usually come together.
