Formula Ocr

核心功能：识别PDF、PNG/JPG等格式里的印刷/手写数学公式，支持复杂多线方程、积分、矩阵等，转为可编辑LaTeX或结构化文本。典型场景：学生、研究者、教育者等将纸质/手写数学内容数字化，如公式截图转LaTeX、扫描文档提取公式。输入为PDF、指定格式图片，输出可存文件或标准输出，需配置MinerU Token。

name: formula-ocr
description: OCR and recognize mathematical formulas from PDFs and images using MinerU. Converts printed or handwritten equations into structured LaTeX or text representation. Features: mathematical formula recognition from PDFs and images (.png, .jpg, .jpeg, .webp). Converts formulas to LaTeX notation. Handles complex multi-line equations, fractions, integrals, and matrices. OCR mode for scanned formula content. Use when you need to: OCR a math formula, recognize equations from images, convert formula screenshots to LaTeX, extract math from scanned documents. Use when asked: 'how do I OCR this formula', 'convert equation image to LaTeX', 'I have a photo of a math formula', 'can my agent recognize mathematical equations', 'is there a skill for formula OCR', 'turn this equation photo into text'. Powered by MinerU (OpenDataLab, Shanghai AI Lab) with advanced formula recognition capabilities. Supports a wide range of mathematical notation. Ideal for students, researchers, educators, and anyone who needs to digitize printed or handwritten mathematical content into editable LaTeX.

Formula Ocr

Convert and extract content from .pdf / images (.png/.jpg/.jpeg/.webp) using MinerU (mineru-open-api).

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# Extract formulas from PDF (requires token)
mineru-open-api extract paper.pdf -o ./out/

# With VLM for better formula accuracy
mineru-open-api extract paper.pdf --model vlm -o ./out/

Authentication

Token required for extract and crawl:

mineru-open-api auth            # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

Supports local files and URLs
Requires token (mineru-open-api auth or MINERU_TOKEN env)
Supported input: .pdf / images (.png/.jpg/.jpeg/.webp)
Language hint with --language (default: ch, use en for English)
Page range with --pages (where applicable)

Notes

Formula recognition requires extract with token. The --formula flag is enabled by default.
Output goes to stdout by default; use -o <dir> to save to file
Binary formats (docx) require -o flag (cannot stream to stdout)
All progress/status messages go to stderr
