 ## 后续计划
 
-- [ ] PDF OCR / 视觉描述增强
+- [ ] **按文档类型提供专用 Chunk 模板**：在现有通用、按行和标识符切分的基础上，为论文、书籍、法律法规、演示文稿、问答和表格等文档提供结构感知的模板，并保留章节路径、页码、内容类型等元数据。
+- [ ] **参考 RAGFlow DeepDoc 完善文档理解层**：在切分前统一完成 OCR、版面分析、表格结构识别、图片/图注关联和文档结构恢复，输出标准化 Block / Document Tree，供不同 Chunk 模板复用。
+- [ ] **完善 OCR 精准识别**：增强扫描 PDF、文档内嵌图片和复杂背景图片的文字识别，补充方向校正、语言检测、置信度过滤与识别结果回填，并建立可量化的准确率评测集。
+- [ ] **引入 Layout Detection 设计**：识别标题、正文、列表、表格、图片、图注、页眉和页脚等版面区域，结合坐标恢复多栏阅读顺序，并保证图片、表格与上下文在切片中的相对位置。
 - [ ] 向量召回（Embedding）
 - [ ] wps 格式支持
