ArUco
A square fiducial marker system proposed by the University of Seville in 2014 that performs pose estimation via corner detection and the PnP algorithm, widely used in robot localization, augmented reality tracking, and camera calibration.

The rule of thumb for reliable ArUco marker detection is that the marker's side length should occupy at least 20–30 pixels in the image, with 40 pixels or more being ideal.
Wide-angle lenses introduce barrel distortion, which distorts the edges of ArUco markers and affects corner extraction accuracy.
A ChArUco board is a hybrid of Checkerboard and ArUco calibration patterns, embedding ArUco markers into the white squares of a chessboard grid, allowing the system to use corner points from visible portions for calibration even when the calibration board is partially occluded.
ArUco markers were proposed by Garrido-Jurado et al. in 2014; they are binary-encoded square markers, each with a unique ID, consisting of a black border and an internal black-and-white grid.
A ChArUco board is a hybrid of Checkerboard and ArUco calibration patterns, and its corner detection can typically achieve sub-pixel accuracy at the 0.05-pixel level.
