Outdoor Scene Graphs Found the Object and Took the Long Way
Five field datasets exposed multimodal embeddings, weak region labels and routes averaging about 66 percent suboptimal efficiency.
Summary
Five field datasets exposed multimodal embeddings, weak region labels and routes averaging about 66 percent suboptimal efficiency.
The field study reports near-70-percent object-retrieval success and compact maps under 600 MB for multi-kilometer trajectories, but around 30 percent of points had outlier ratios above 0.1 and region-level F1 averaged about 0.359. The scene graphs worked, with traversability and semantic structure still limiting them.
Why it matters
Five field datasets exposed multimodal embeddings, weak region labels and routes averaging about 66 percent suboptimal efficiency.
Limits and context
No additional limitation was separately recorded.
Key claims
Five field datasets exposed multimodal embeddings, weak region labels and routes averaging about 66 percent suboptimal efficiency.
