Sample Project

A sample dataset demonstrating the calibration workflow is available for download.

The sample project is a 5-camera setup with charuco extrinsic calibration and hardware-synchronized timestamps. It contains raw input data only: intrinsic calibration videos, extrinsic calibration videos with timestamps, and one walking recording. You configure calibration targets and run the pipeline yourself following the documentation.

The intrinsic calibration videos use a chessboard rather than a charuco board. This produces a slightly worse intrinsic calibration (~1 px reprojection error). A charuco board will give better results. The extrinsic calibration uses a charuco board.

For a scripting-based alternative to the GUI walkthrough, see scripts/demo_api.py which runs the same calibration pipeline programmatically.
