Overview

9-view X-Ray Fanbeam Calibration provides tools for precise calibration of X-ray imaging systems. These tools enable researchers to detect objects, align calibration setups, and visualize 3D data. Below are the key functionalities and their usage instructions.

Features

• Bead Detection: Automatic bead localization in X-ray images.
• Calibration: Multi-view geometric calibration.
• 3D Visualization: Open3D-based interactive viewer.
• Box Fitting: Bounding box fitting for 3D structures.
• Triangulation: Multi-view triangulation of detected objects.
• RANSAC Visual Hull: Robust model fitting for 3D structures.
