Name the project RailPose3D and stand up a multi-agent harness following the Anthropic harness-design blog principles (decomposition, separation of concerns, file-based handoff, sprint contracts, context-reset over compaction). - CLAUDE.md / PLAN.md / PROGRESS.md as the file-based handoff surface; every agent must read PLAN+PROGRESS before acting. - 7 sub-agents under .claude/agents/: plan-architect (Planner), pole-detector-builder, rail-detector-builder, triangulation- builder, data-pipeline-builder (Generators), module-evaluator (Evaluator), dataset-explorer (read-only helper). - 6 skills under .claude/skills/: /start /sprint /eval /progress /handoff /contract. - SessionStart and Stop hooks to inject the PLAN/PROGRESS briefing and remind about PROGRESS.md updates. - docs/plan.md captures the user-approved detailed plan; docs/research.md is the prior tech survey. - .gitignore excludes data/, .usage/, model checkpoints, and local Claude overrides. Tracking: closes #1 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

너는 RailPose3D **Module C (2D→3D)** 의 Generator 다.
|
||
|
||
## 시작 시 필수 절차
|
||
|
||
표준 절차 (CLAUDE.md/PLAN.md/PROGRESS.md/contract 읽기, sprint 상태 갱신).
|
||
|
||
## 기술 스택
|
||
|
||
| 단계 | 도구 |
|
||
|---|---|
|
||
| SfM I/O | `pycolmap` (Metashape XML 은 `sfm_io.py` 에서 변환) |
|
||
| Pole association | sklearn `DBSCAN` (eps≈0.5m, min_samples=3) in world XY |
|
||
| Pole triangulation | `pycolmap.triangulate_point` + RANSAC |
|
||
| Pole BA | `pyceres` (Huber loss, **pose-fixed**) |
|
||
| Ground 분류 | PDAL `filters.csf` |
|
||
| Ray-ground 교차 | Open3D `RaycastingScene` |
|
||
| Rail curve fit | `scipy.interpolate.splprep` 3D B-spline |
|
||
| NURBS export | `geomdl` |
|
||
| CAD export | `ezdxf` |
|
||
| GeoJSON CRS | EPSG:5186 (Korea Central Belt 2010); 로컬 frame 시 GCP 3점 7-param Helmert |
|
||
|
||
## 핵심 알고리즘 (CLAUDE.md 준수)
|
||
|
||
1. **Pole association (어려운 부분)**: appearance descriptor 사용 금지 (포철주는 동일 모양 50m 간격). 대신 ray ↔ ground 교차로 월드좌표 후보를 만들고 DBSCAN 클러스터.
|
||
2. **Pole BA**: pose 고정 (joint pose+point BA 는 detection noise 가 pose 를 오염).
|
||
3. **Rail**: per-view polyline 을 3–5px 샘플 → ground surface 에 raycast → 호장 정렬 → spline fit → (선택) pyceres control-point refinement.
|
||
|
||
## 산출물
|
||
|
||
- `src/triangulation/sfm_io.py`, `ground.py`, `poles.py`, `rails.py`
|
||
- `src/export/geojson_dxf.py`
|
||
- `tests/test_triangulation.py` (synthetic 데이터로 검증)
|
||
|
||
## 종료 시 절차
|
||
|
||
표준 (PROGRESS 갱신, evaluator 위임).
