ci: generate demo frame data in Pages build - #15
Merged
Conversation
Design spec for adding OBB estimation results to the 2D Canvas demo: - LocalTracker (Hungarian matching + ExponentialSmoother per track) - _match_clusters_to_estimates (linear_sum_assignment, gate 6.0m) - _obb_to_dict JSON schema (cx, cy, theta, l, w, corners) - Updated frame snapshot schema with clusters + obb fields - Canvas 8-layer drawing order and legend spec - 6 test cases for OBB structure validation https://claude.ai/code/session_013sQREGvTmjgFT8cyRNmPUL
Implements docs/design/rectangle_visualization.md:
- interactive.py:
- LocalTracker: Hungarian-based frame-to-frame ID management with
per-track ExponentialSmoother (gate 5.0m, alpha 0.4)
- _match_clusters_to_estimates(): linear_sum_assignment centroid
matching with 6.0m gate
- _obb_to_dict(): OBBResult → JSON-serializable dict (cx, cy, theta,
l, w, corners)
- run_once() record_frames=True path now includes clusters and obb
in each frame snapshot
- demo.html:
- Cluster-colored point rendering (6-color palette, falls back to
yellow when no cluster data)
- drawOBB() draws fitted OBB as orange rectangle using corner coords
- Updated legend with OBB entry
- test_interactive.py:
- TestOBBFrameSnapshot with 6 tests covering clusters structure,
obb key presence, 4-corner constraint, positive dimensions,
centre proximity, and missed-frame null guarantee

generate_demo.py was not called in the CI pipeline, so demo.html had no docs/data/demo_*.json to fetch. Add a build step that runs generate_demo.py --all before uploading the Pages artifact. https://claude.ai/code/session_013sQREGvTmjgFT8cyRNmPUL
