Camera Calibration Helpers

Set of scripts to support camera calibration tasks (specifically using ps3eye cameras)

Scripts

charuco_board/generate_charuco.py

Generate print-ready ChArUco boards as single-page PDFs or tiled multi-page PDFs with crop marks, tile labels, and a minimap for assembly. Use this to create the physical calibration target that the rest of the tools expect.

ps3eye_tools/test_ps3eye_focus.py

Small utilities for quick sanity checks with a PS3 Eye camera. Use them to confirm device access, dial in exposure, and judge focus before running calibration.

live_calibration/live_charuco_calibration.py

Interactive capture tool for collecting ChArUco observations in real time. It shows a live preview with an optional coverage heatmap, accepts frames that meet your detection/quality thresholds, and periodically recalibrates to give immediate feedback on reprojection error and coverage gaps.
