Researchers have identified a new failure mode in monocular depth estimation models, termed the "3D Mirage." This phenomenon occurs when models hallucinate illusory 3D structures from ambiguous inputs, despite achieving remarkable generalization. The paper introduces a framework to probe, score, and mitigate this safety risk. It includes a new benchmark, "3D-Mirage," and proposes metrics like the Deviation Composite Score (DCS) and Confusion Composite Score (CCS) to evaluate structural and contextual robustness. A parameter-efficient strategy called Grounded Self-Distillation is presented to resolve hallucinations without causing catastrophic forgetting. AI
