# Design: Refactor Dual-Track Architecture
|
||||
|
||||
## Context
|
||||
|
||||
Tool_OCR 是一個雙軌制文件處理系統,支援:
|
||||
- **Direct Track**: 從可編輯 PDF 直接提取結構化內容
|
||||
- **OCR Track**: 使用 PaddleOCR + PP-StructureV3 進行光學字符識別
|
||||
|
||||
目前系統存在以下技術債務:
|
||||
- OCRService (2,326 行) 承擔過多職責
|
||||
- PDFGeneratorService (4,644 行) 是單體服務
|
||||
- 記憶體管理分散在多個組件中
|
||||
- 已知 bug 影響輸出品質
|
||||
|
||||
## Goals / Non-Goals
|
||||
|
||||
### Goals
|
||||
- 修復 PLAN.md 中列出的所有已知 bug
|
||||
- 將 OCRService 拆分為 < 800 行的可維護單元
|
||||
- 將 PDFGeneratorService 拆分為 < 2,000 行
|
||||
- 簡化記憶體管理配置
|
||||
- 提升前端狀態管理一致性
|
||||
|
||||
### Non-Goals
|
||||
- 不改變現有 API 契約
|
||||
- 不引入新的外部依賴
|
||||
- 不改變資料庫 schema
|
||||
- 不改變使用者介面
|
||||
|
||||
## Decisions
|
||||
|
||||
### Decision 1: 使用 PyMuPDF find_tables() 取代自定義表格檢測
|
||||
|
||||
**選擇**: 使用 PyMuPDF 內建的 `page.find_tables()` API
|
||||
|
||||
**理由**:
|
||||
- PyMuPDF 的表格檢測能正確識別合併單元格
|
||||
- 返回的 `table.cells` 結構包含 span 資訊
|
||||
- 減少自定義代碼維護負擔
|
||||
|
||||
**替代方案**:
|
||||
- 改進 `_detect_tables_by_position()` 算法
|
||||
- 優點:不依賴外部 API 變更
|
||||
- 缺點:複雜度高,難以處理所有邊界情況
|
||||
- 使用 Camelot 或 Tabula
|
||||
- 優點:成熟的表格提取庫
|
||||
- 缺點:引入新依賴,增加系統複雜度
|
||||
|
||||
### Decision 2: 使用 Strategy Pattern 重構服務層
|
||||
|
||||
**選擇**: 引入 ProcessingOrchestrator 使用策略模式
|
||||
|
||||
```python
|
||||
class ProcessingPipeline(Protocol):
|
||||
def process(self, file_path: str, options: ProcessingOptions) -> UnifiedDocument:
|
||||
...
|
||||
|
||||
class DirectPipeline(ProcessingPipeline):
|
||||
def __init__(self, extraction_engine: DirectExtractionEngine):
|
||||
self.engine = extraction_engine
|
||||
|
||||
def process(self, file_path, options):
|
||||
return self.engine.extract(file_path)
|
||||
|
||||
class OCRPipeline(ProcessingPipeline):
|
||||
def __init__(self, ocr_service: OCRService, preprocessor: LayoutPreprocessingService):
|
||||
self.ocr = ocr_service
|
||||
self.preprocessor = preprocessor
|
||||
|
||||
def process(self, file_path, options):
|
||||
# Preprocessing + OCR + Conversion
|
||||
...
|
||||
|
||||
class ProcessingOrchestrator:
|
||||
def __init__(self, detector: DocumentTypeDetector, pipelines: dict[str, ProcessingPipeline]):
|
||||
self.detector = detector
|
||||
self.pipelines = pipelines
|
||||
|
||||
def process(self, file_path, options):
|
||||
track = options.force_track or self.detector.detect(file_path).track
|
||||
return self.pipelines[track].process(file_path, options)
|
||||
```
|
||||
|
||||
**理由**:
|
||||
- 職責分離:檢測、處理、轉換各自獨立
|
||||
- 易於測試:可以單獨測試每個 Pipeline
|
||||
- 易於擴展:新增處理方式只需添加新 Pipeline
|
||||
|
||||
**替代方案**:
|
||||
- 使用 Chain of Responsibility
|
||||
- 優點:更靈活的處理鏈
|
||||
- 缺點:對於二選一的場景過於複雜
|
||||
- 保持現狀,只做代碼整理
|
||||
- 優點:風險最低
|
||||
- 缺點:無法解決根本問題
|
||||
|
||||
### Decision 3: 分層提取 PDF 生成邏輯
|
||||
|
||||
**選擇**: 將 PDFGeneratorService 拆分為三個模組
|
||||
|
||||
```
|
||||
PDFGeneratorService (主要編排)
|
||||
├── PDFTableRenderer (表格渲染)
|
||||
│ ├── HTMLTableParser (HTML 表格解析)
|
||||
│ └── CellRenderer (單元格渲染)
|
||||
├── PDFFontManager (字體管理)
|
||||
│ ├── FontLoader (字體載入)
|
||||
│ └── FontFallback (字體 fallback)
|
||||
└── PDFLayoutEngine (版面配置)
|
||||
```
|
||||
|
||||
**理由**:
|
||||
- 單一職責:每個模組專注一件事
|
||||
- 可重用:FontManager 可被其他服務使用
|
||||
- 易於測試:表格渲染可獨立測試
|
||||
|
||||
### Decision 4: 統一記憶體策略引擎
|
||||
|
||||
**選擇**: 合併記憶體管理組件為單一 MemoryPolicyEngine
|
||||
|
||||
```python
|
||||
class MemoryPolicyEngine:
|
||||
"""統一的記憶體策略引擎"""
|
||||
|
||||
def __init__(self, config: MemoryConfig):
|
||||
self.config = config
|
||||
self._semaphore = asyncio.Semaphore(config.max_concurrent_predictions)
|
||||
|
||||
@property
|
||||
def gpu_usage_percent(self) -> float:
|
||||
# 統一的 GPU 使用率查詢
|
||||
...
|
||||
|
||||
def check_availability(self) -> MemoryStatus:
|
||||
# 返回 AVAILABLE, WARNING, CRITICAL, EMERGENCY
|
||||
...
|
||||
|
||||
async def acquire_prediction_slot(self):
|
||||
# 統一的並發控制
|
||||
...
|
||||
|
||||
def cleanup_if_needed(self):
|
||||
# 根據狀態自動清理
|
||||
...
|
||||
|
||||
@dataclass
|
||||
class MemoryConfig:
|
||||
warning_threshold: float = 0.80 # 80%
|
||||
critical_threshold: float = 0.95 # 95%
|
||||
max_concurrent_predictions: int = 2
|
||||
model_idle_timeout: int = 300 # 5 minutes
|
||||
```
|
||||
|
||||
**理由**:
|
||||
- 減少配置項:從 8+ 降到 4 個核心配置
|
||||
- 簡化依賴:服務只需依賴一個記憶體引擎
|
||||
- 統一行為:所有記憶體決策在同一處做出
|
||||
|
||||
### Decision 5: 使用 Zustand 管理任務狀態
|
||||
|
||||
**選擇**: 新增 TaskStore 統一管理任務狀態
|
||||
|
||||
```typescript
|
||||
interface TaskState {
|
||||
currentTaskId: string | null;
|
||||
tasks: Record<string, TaskDetail>;
|
||||
processingStatus: Record<string, ProcessingStatus>;
|
||||
}
|
||||
|
||||
interface TaskActions {
|
||||
setCurrentTask: (taskId: string) => void;
|
||||
updateTask: (taskId: string, updates: Partial<TaskDetail>) => void;
|
||||
updateProcessingStatus: (taskId: string, status: ProcessingStatus) => void;
|
||||
clearTasks: () => void;
|
||||
}
|
||||
|
||||
const useTaskStore = create<TaskState & TaskActions>()(
|
||||
persist(
|
||||
(set) => ({
|
||||
currentTaskId: null,
|
||||
tasks: {},
|
||||
processingStatus: {},
|
||||
// ... actions
|
||||
}),
|
||||
{ name: 'task-storage' }
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
**理由**:
|
||||
- 一致性:與現有 uploadStore、authStore 模式一致
|
||||
- 可追蹤:任務狀態變更集中管理
|
||||
- 持久化:刷新頁面後狀態保留
|
||||
|
||||
## Risks / Trade-offs
|
||||
|
||||
| 風險 | 影響 | 緩解措施 |
|
||||
|------|------|----------|
|
||||
| PyMuPDF find_tables() API 變更 | 中 | 封裝為獨立函數,易於替換 |
|
||||

- 每個 Step 獨立部署,問題時可回滾到上一個穩定版本
|
||||
- Bug fixes 優先,確保基本功能正確
|
||||
- 重構不改變外部行為,回滾影響最小
|
||||
|
||||
## Open Questions
|
||||
|
||||
1. **PyMuPDF find_tables() 的版本相容性**: 需確認目前使用的 PyMuPDF 版本是否支援此 API
|
||||
2. **前端狀態持久化範圍**: 是否所有任務都需要持久化,還是只保留當前會話?
|
||||
3. **記憶體閾值調整**: 現有閾值是否經過生產驗證,可以直接沿用?

# Change: Refactor Dual-Track Architecture
|
||||
|
||||
## Why
|
||||
|
||||
目前雙軌制 OCR 系統存在多個已知問題和架構債務:
|
||||
|
||||
1. **Direct Track 表格問題**: `_detect_tables_by_position()` 無法識別合併單元格,導致 edit3.pdf 產生 204 個錯誤拆分的 cells(應為 83 個)
|
||||
2. **OCR Track 圖片路徑丟失**: CHART/DIAGRAM 等視覺元素的 `saved_path` 在轉換時丟失,導致圖片未放回 PDF
|
||||
3. **OCR Track cell_boxes 座標錯亂**: PP-StructureV3 返回的 cell_boxes 超出頁面邊界
|
||||
4. **服務層過度複雜**: OCRService (2,326 行) 承擔過多職責,難以維護和測試
|
||||
5. **PDF 生成器過於龐大**: PDFGeneratorService (4,644 行) 是單體服務,難以擴展
|
||||
|
||||
## What Changes
|
||||
|
||||
### Phase 1: 修復已知 Bug(優先級:最高)
|
||||
|
||||
- **Direct Track 表格修復**: 改用 PyMuPDF `find_tables()` API 取代 `_detect_tables_by_position()`
|
||||
- **OCR Track 圖片路徑修復**: 擴展 `_convert_pp3_element` 處理所有視覺元素類型 (IMAGE, FIGURE, CHART, DIAGRAM, LOGO, STAMP)
|
||||
- **Cell boxes 座標驗證**: 添加邊界檢查,超出範圍時使用 CV 線檢測 fallback
|
||||
- **過濾極小裝飾圖片**: 過濾 < 200 px² 的圖片
|
||||
- **移除覆蓋圖像**: 在渲染階段過濾與 covering_images 重疊的圖片
|
||||
|
||||
### Phase 2: 服務層重構(優先級:高)
|
||||
|
||||
- **拆分 OCRService**: 提取獨立的 `ProcessingOrchestrator` 負責流程編排
|
||||
- **建立 Pipeline 模式**: 使用組合模式取代目前的聚合模式
|
||||
- **提取 TableRenderer**: 從 PDFGeneratorService 提取表格渲染邏輯
|
||||
- **提取 FontManager**: 從 PDFGeneratorService 提取字體管理邏輯
|
||||
|
||||
### Phase 3: 記憶體管理簡化(優先級:中)
|
||||
|
||||
- **統一記憶體策略**: 合併 MemoryManager、MemoryGuard、各類 Semaphore 為單一策略引擎
|
||||
- **簡化配置**: 減少 8+ 個記憶體相關配置項到核心 3-4 項
|
||||
|
||||
### Phase 4: 前端狀態管理改進(優先級:中)
|
||||
|
||||
- **新增 TaskStore**: 使用 Zustand 管理任務狀態,取代分散的 useState
|
||||
- **合併類型定義**: 統一 api.ts 和 apiV2.ts 為單一類型定義檔案
|
||||
|
||||
## Impact
|
||||
|
||||
- Affected specs: `document-processing`
|
||||
- Affected code:
|
||||
- `backend/app/services/direct_extraction_engine.py` (表格檢測)
|
||||
- `backend/app/services/ocr_to_unified_converter.py` (元素轉換)
|
||||
- `backend/app/services/ocr_service.py` (服務編排)
|
||||
- `backend/app/services/pdf_generator_service.py` (PDF 生成)

||||
- `backend/app/services/memory_manager.py` (記憶體管理)
|
||||
- `frontend/src/store/` (狀態管理)
|
||||
- `frontend/src/types/` (類型定義)
|
||||
|
||||
## Risk Assessment
|
||||
|
||||
| 風險 | 嚴重性 | 緩解措施 |
|
||||
|------|--------|----------|
|
||||
| 表格渲染回歸 | 高 | 使用 edit.pdf 和 edit3.pdf 作為回歸測試 |
