* fix(ocr_mkcontent): improve language detection and content formatting (#458)

Optimize the language detection logic to enhance content formatting.  This
change addresses issues with long word segmentation. Language detection now uses a
threshold to determine the language of a text based on the proportion of English characters.
Formatting rules for content have been updated to consider a list of languages (initially
including Chinese, Japanese, and Korean) where no space is added between content segments
for inline equations and text spans, improving the handling of Asian languages.

The impact of these changes includes improved accuracy in language detection, better
segmentation of long words, and more appropriate spacing in content formatting for multiple
languages.

* fix(self_modify): merge detection boxes for optimized text region detection (#448)

Merge adjacent and overlapping detection boxes to optimize text region detection in
the document. Post processing of text boxes is enhanced by consolidating them into
larger text lines, taking into account their vertical and horizontal alignment. This
improvement reduces fragmentation and improves the readability of detected text blocks.

* fix(pdf-extract): adjust box threshold for OCR detection (#447)

Tuned the detection box threshold parameter in the OCR model initialization to improve the
accuracy of text extraction from images. The threshold was modified from 0.6 to
0.3 to filter out smaller detection boxes, which is expected to enhance the quality of the extracted
text by reducing noise and false positives in the OCR process.

* fix(pdf-extract-kit): adjust crop_paste parameters for better accuracyThe crop_paste_x and crop_paste_y values in the pdf_extract_kit.py have been modified
to improve the accuracy and consistency of OCR processing. The new values are set to 25
to ensure more precise image cropping and pasting which leads to better OCR recognition
results.

* fix(pdf-extract-kit): increase crop_paste margin for OCR processingDouble the crop_paste margin from25 to 50 to ensure better OCR accuracy and
handling of border cases. This change will help in improving the overall quality of
OCR'ed text by providing more context around the detected text areas.

* fix(common): deep copy model list before drawing model bbox

Use a deep copy of the original model list in `drow_model_bbox` to avoid potential
modifications to the source data. This ensures the integrity of the original models
is maintained while generating the model bounding boxes visualization.

* refactor(pdf_extract_kit): implement singleton pattern for atomic models (#533)

Refactor the pdf_extract_kit module to utilize a singleton pattern when initializing
atomic models. This change ensures that atomic models are instantiated at most once,
optimizing memory usage and reducing redundant initialization steps. The AtomModelSingleton
class now manages the instantiation and retrieval of atomic models, improving the
overall structure and efficiency of the codebase.

快速开始

如果遇到任何安装问题,请先查询 FAQ
如果遇到解析效果不及预期,参考 Known Issues
有3种不同方式可以体验MinerU的效果

⚠️安装前必看——软硬件环境支持说明

为了确保项目的稳定性和可靠性,我们在开发过程中仅对特定的软硬件环境进行优化和测试。这样当用户在推荐的系统配置上部署和运行项目时,能够获得最佳的性能表现和最少的兼容性问题。

通过集中资源和精力于主线环境我们团队能够更高效地解决潜在的BUG及时开发新功能。

在非主线环境中由于硬件、软件配置的多样性以及第三方依赖项的兼容性问题我们无法100%保证项目的完全可用性。因此对于希望在非推荐环境中使用本项目的用户我们建议先仔细阅读文档以及FAQ大多数问题已经在FAQ中有对应的解决方案除此之外我们鼓励社区反馈问题以便我们能够逐步扩大支持范围。

操作系统
Ubuntu 22.04 LTS Windows 10 / 11 macOS 11+
CPU x86_64 x86_64 x86_64 / arm64
内存 大于等于16GB推荐32G以上
python版本 3.10
Nvidia Driver 版本 latest(专有驱动) latest None
CUDA环境 自动安装[12.1(pytorch)+11.8(paddle)] 11.8(手动安装)+cuDNN v8.7.0(手动安装) None

使用CPU快速体验

1. 安装magic-pdf

最新版本国内镜像源同步可能会有延迟,请耐心等待

conda create -n MinerU python=3.10
conda activate MinerU
pip install -U magic-pdf[full] --extra-index-url https://wheels.myhloli.com -i https://pypi.tuna.tsinghua.edu.cn/simple

2. 下载模型权重文件

详细参考 如何下载模型文件

️模型下载后请务必检查模型文件是否下载完整

请检查目录下的模型文件大小与网页上描述是否一致如果可以的话最好通过sha256校验模型是否下载完整

3. 拷贝配置文件并进行配置

在仓库根目录可以获得 magic-pdf.template.json 配置模版文件

️务必执行以下命令将配置文件拷贝到【用户目录】下,否则程序将无法运行

windows的用户目录为 "C:\Users\用户名", linux用户目录为 "/home/用户名", macOS用户目录为 "/Users/用户名"

cp magic-pdf.template.json ~/magic-pdf.json

在用户目录中找到magic-pdf.json文件并配置"models-dir"为2. 下载模型权重文件中下载的模型权重文件所在目录

️务必正确配置模型权重文件所在目录的【绝对路径】,否则会因为找不到模型文件而导致程序无法运行

windows系统中此路径应包含盘符且需把路径中所有的"\"替换为"/",否则会因为转义原因导致json文件语法错误。

例如模型放在D盘根目录的models目录则model-dir的值应为"D:/models"

{
  // other config
  "models-dir": "D:/models",
  "table-config": {
        "model": "TableMaster", // 使用structEqTable请修改为'struct_eqtable'
        "is_table_recog_enable": false, // 表格识别功能默认是关闭的,如果需要修改此处的值
        "max_time": 400
    }
}

使用GPU

如果您的设备支持CUDA且满足主线环境中的显卡要求则可以使用GPU加速请根据自己的系统选择适合的教程

  • Ubuntu22.04LTS + GPU
  • Windows10/11 + GPU
  • 使用Docker快速部署

    Docker 需设备gpu显存大于等于16GB默认开启所有加速功能

    运行本docker前可以通过以下命令检测自己的设备是否支持在docker上使用CUDA加速

    docker run --rm --gpus=all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
    
    wget https://github.com/opendatalab/MinerU/raw/master/Dockerfile
    docker build -t mineru:latest .
    docker run --rm -it --gpus=all mineru:latest /bin/bash
    magic-pdf --help
    

使用

命令行

magic-pdf --help
Usage: magic-pdf [OPTIONS]

Options:
  -v, --version                display the version and exit
  -p, --path PATH              local pdf filepath or directory  [required]
  -o, --output-dir TEXT        output local directory
  -m, --method [ocr|txt|auto]  the method for parsing pdf.
                               ocr: using ocr technique to extract information from pdf,
                               txt: suitable for the text-based pdf only and outperform ocr,
                               auto: automatically choose the best method for parsing pdf
                                  from ocr and txt.
                               without method specified, auto will be used by default.
  --help                       Show this message and exit.


## show version
magic-pdf -v

## command line example
magic-pdf -p {some_pdf} -o {some_output_dir} -m auto

其中 {some_pdf} 可以是单个pdf文件也可以是一个包含多个pdf文件的目录。 运行完命令后输出的结果会保存在{some_output_dir}目录下, 输出的文件列表如下

├── some_pdf.md                          # markdown 文件
├── images                               # 存放图片目录
├── some_pdf_layout.pdf                  # layout 绘图
├── some_pdf_middle.json                 # minerU 中间处理结果
├── some_pdf_model.json                  # 模型推理结果
├── some_pdf_origin.pdf                  # 原 pdf 文件
└── some_pdf_spans.pdf                   # 最小粒度的bbox位置信息绘图

TODO

TODO

  • 基于语义的阅读顺序
  • 正文中列表识别
  • 正文中代码块识别
  • 目录识别
  • 表格识别
  • 化学式识别
  • 几何图形识别

Known Issues

  • 阅读顺序基于规则的分割,在一些情况下会乱序
  • 不支持竖排文字
  • 列表、代码块、目录在layout模型里还没有支持
  • 漫画书、艺术图册、小学教材、习题尚不能很好解析
  • 在一些公式密集的PDF上强制启用OCR效果会更好
  • 如果您要处理包含大量公式的pdf,强烈建议开启OCR功能。使用pymuPDF提取文字的时候会出现文本行互相重叠的情况导致公式插入位置不准确。
