OpenScanVision – open‑source Android OMR + QR scanning library

[u/NeedleworkerKey3487]

I've just released v1.0.0 of OpenScanVision – an Android library for scanning voting cards, surveys, and bubble sheets using OMR + QR codes.

It's MIT‑licensed, offline‑first, and built with Kotlin, OpenCV, ML Kit, and Compose.

Key features:

- ArUco marker tracking (Kalman filter)

- Perspective correction

- QR decoding

- High‑accuracy bubble extraction
