MinerU是一个将复杂文档（如PDF）转换为LLM就绪的markdown/JSON格式的工具，用于Agentic工作流。相比传统PDF解析工具，MinerU在文档结构解析、多媒体提取、公式识别等方面有着显著优势。

主要功能包括：

• 文档结构解析：移除页眉页脚、脚注、页码等，确保语义连贯性
• 内容提取：输出按人类可读顺序排列的文本，支持单列、多列和复杂布局
• 格式保持：保留原始文档结构（标题、段落、列表等）
• 多媒体提取：提取图像、图像描述、表格、表格标题和脚注
• 公式识别：自动将文档中的公式转换为LaTeX格式
• 表格识别：自动将表格转换为HTML格式
• OCR支持：自动检测扫描版PDF并启用OCR功能，支持84种语言
• 多平台支持：兼容Windows、Linux、Mac平台，支持CPU/GPU/NPU加速

2、环境准备与安装

2.1 硬件要求

• CPU推理：支持纯CPU环境
• GPU要求：Turing架构及以上，6GB+显存（pipeline后端）或8GB+显存（VLM后端）
• 内存要求：最低16GB+，推荐32GB+
• 磁盘空间：20GB+，建议SSD
• Python版本：3.10-3.13

2.2 安装方法

（1）使用pip或uv安装

（2）基于源码安装

（3）Docker部署

项目提供Docker部署方式，可快速搭建环境解决兼容性问题。

3、配置文件详解

MinerU提供了灵活的配置选项，主要包括：

• 解析后端设置（pipeline和VLM两种）
• 输出格式选择（Markdown、JSON等）
• OCR语言设置
• 图像和表格处理参数

配置文件通常包括解析精度、资源使用限制等关键参数，可以根据需要进行调整。
