arXiv:2606.29600v1 Announce Type: cross Abstract: A faithful 3D world representation should account for layered geometry, where a single camera ray may contain multiple visible and geometrically valid surfaces. Monocular depth estimation, however, reduces this structure to one scalar depth per pixel. Transparent scenes make this ambiguity measurable: the same ray can pass through foreground glass and observe the background, turning the supervised target into a convention of annotation, data, and training rather than a scene-intrinsic truth. A learned predictor exposes this convention as its de
The proliferation of monocular foundation models for 3D understanding highlights the need to probe their intrinsic limitations and conventions, especially as their deployment becomes widespread.
Improving the accuracy and robustness of 3D world representations from monocular vision is crucial for advanced AI applications, particularly in robotics and autonomous systems where geometric understanding is paramount.
This research provides a deeper understanding of geometric ambiguities in monocular depth estimation, which could lead to new model architectures or data annotation strategies that account for layered geometry.

Refined monocular depth estimation models will emerge that better handle complex and transparent scenes.
This enhanced 3D perception will improve the safety and capability of autonomous robots and vehicles operating in real-world, ambiguous environments.
More sophisticated robotic interaction with multi-layered environments, such as distinguishing objects behind glass, could unlock new applications in manufacturing or logistics.
