# SafeVisionAI — Data Acquisition Scripts 🔬

These scripts are the **raw data pipeline** that built the 3.6GB SafeVisionAI dataset.
All scripts here are **pure Python** — they require no database, no Redis, no PostGIS.

> Scripts are mirrored from the [SafeVisionAI main repo](https://github.com/SafeVision-AI/SafeVision-AI) and organized by their origin folder.
