The problem

Contemporary BEV perception, aerial localization, and landmark-guided navigation models increasingly condition their visual representations on OpenStreetMap (OSM) vector geometry and metadata. In practice, OSM data exhibits severe geographic disparities, missing road classes, topological errors, and incomplete landmark tags. Because existing methods assume clean and complete vector maps as an operational precondition, system performance degrades unpredictably in under-mapped or rural areas, preventing deployment outside densely curated metropolitan regions.

Why it matters

Enables map-conditioned autonomous navigation and visual localization systems to reliably detect when OSM priors are missing or erroneous, dynamically falling back to visual perception rather than failing catastrophically.

Ways to approach it

Prior-work checks are free with an account. Results someone already ran are shown to everyone.

  1. 1

    Controlled Map-Corruption Stress Testing: Synthetically corrupt OSM metadata and vector topology (e.g., dropping road segments, perturbing node coordinates, masking landmark tags) across existing datasets like nuScenes, CityNav, and OpenStreetView-5M to measure the degradation curves of current state-of-the-art map-conditioned models.

  2. 2

    Cross-Regional Heterogeneity Evaluation: Evaluate navigation and localization performance across a globally diverse geographic spectrum where OSM completeness naturally varies, measuring the exact correlation between OSM feature density metrics and perception failure modes.

  3. 3

    Fallback and Uncertainty-Aware Conditioning: Implement an uncertainty-gated fusion module that detects discrepancies between online visual observations and OSM priors, measuring localization accuracy and route completion rate when relying primarily on vision under corrupted map segments.

Why it might fail

If commercial standard-definition mapping platforms achieve near-universal global completeness and automated verification before academic solutions mature, or if purely visual end-to-end foundation models render external vector map conditioning obsolete.

Robust Cross-View Perception and Localization Without Paired Ground-Level Street Imagery

Current cross-view visual geolocalization, 3D scene reconstruction, and BEV perception models strictly depend on dense, spatially calibrated ground-level panoramas paired with satellite imagery or pre-existing 3D city meshes. In rural, sparsely populated, or underdeveloped regions, ground-level street-view coverage is either completely absent or uncalibrated. This reliance on dense ground-level imagery structurally restricts cross-view perception algorithms to major metropolitan areas with dedicated mapping fleets.

Benchmarking and Mitigating UAV Perception Failure Under Rapid Motion Blur, Scale Shifts, and Occlusion

Current perception models deployed on unmanned aerial vehicles achieve low absolute accuracy on standard downstream tasks (e.g., recall under 7.5% in scene understanding, under 40% in action recognition, and under 30% m_vIoU in tracking). These failures are driven by real-world flight conditions—rapid camera motion blur, extreme resolution and altitude shifts, severe occlusion, and small target sizes—that standard benchmarks do not systematically couple. As a consequence, aerial vision pipelines remain brittle and cannot be reliably trusted for autonomous navigation, search-and-rescue, or monitoring in complex flight regimes.
