GeoCalib is an algorithm for single-image calibration: it estimates the camera intrinsics and gravity direction from a single image only. By combining geometric optimization with deep learning, GeoCalib provides a more flexible and accurate calibration compared to previous approaches.
The main purpose of this tool is to automate image optimization and analysis. This project is recent, so use it with care, I'm listening to all feedback (we can talk via [twitter][twitter], don't follow me I never tweet).
