Spatial Fusion Error — Multimodal Long Context

🧭 Quick Return to Map

You are in a sub-page of Multimodal_LongContext.
To reorient, go back here:

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

When spatial information from different modalities (text, image, video, 3D layout) is fused incorrectly,
the model builds a distorted scene map. This results in answers that are locally fluent but spatially wrong.


What this page is

  • A repair map for spatial mis-fusion across long multimodal windows.
  • Structural checks that keep anchors aligned in 2D/3D space.
  • Copy-paste prompts to enforce spatial traceability in multimodal RAG.

When to use

  • Text says "object A is left of object B" but visual encoder aligns them oppositely.
  • Bounding boxes overlap or merge, losing spatial independence.
  • 3D → 2D projection mismatch: captions reference an object that isn’t in frame.
  • Video QA drifts: same entity appears in different spots across time.
  • Answers mention correct objects but wrong spatial relations (left/right, inside/outside, above/below).

Open these first


Common failure patterns

  • Axis flip — left/right or up/down swapped.
  • Projection drift — 3D object references collapse to wrong 2D bounding box.
  • Overlap collapse — two entities share the same spatial slot.
  • Cross-modal mismatch — text anchor doesn’t correspond to visual bounding box.

Fix in 60 seconds

  1. Spatial schema lock

    • Represent anchors as {id, coords(x,y,z), frame_id}.
    • Reject answers missing explicit spatial schema.
  2. ΔS probe across modalities

    • Compute ΔS(text_anchor, visual_anchor).
    • If ΔS ≥ 0.60, suspect fusion error.
  3. Spatial IoU check

    • Enforce IoU ≥ 0.7 for same anchor across modalities.
    • If < 0.7, assign new anchor ID.
  4. Stabilize with BBCR

    • Bridge text ↔ visual mismatch with constraint re-anchoring.
    • Clamp variance with BBAM.
  5. Trace audit

    • Log {anchor_id, modality, coords, IoU}.
    • Require cite-then-answer with explicit anchor IDs.

Copy-paste prompt

You have TXT OS and the WFGY Problem Map.

Task: Detect and repair spatial fusion errors across modalities.

Steps:
1. Verify each anchor has {id, coords(x,y,z), frame_id}.
2. Compute IoU across modalities. If IoU < 0.7, treat as mismatch.
3. Probe ΔS across text and visual anchors.
4. Apply BBCR if drift detected, else assign new ID.
5. Return:
   - stable anchors
   - mismatched anchors
   - ΔS values and λ states
   - corrected spatial map

Acceptance targets

  • 100% anchors represented with explicit {id, coords, frame_id}.
  • Cross-modal IoU ≥ 0.7 after fix.
  • ΔS(text, visual) ≤ 0.45.
  • λ remains convergent across paraphrases.
  • No axis flip errors across test prompts.
