Calibration Targets
Calibration Targets
axon describes the physical calibration board once, then dispatches target-specific detection internally for every calibrator. This tutorial covers the three supported target types and their detection skills.
Target Types
Define a chessboard, ChArUco, or ArUco board once, and pass it to any Axon calibrator.
All Supported Targets
Reference for every target type, ArUco dictionaries, and target selection best practices.
View →ChessboardTarget
Classic chessboard, described by its grid of inner corners.
View →CharucoTarget
Chessboard with embedded ArUco markers, the recommended target for eye-in-hand and multi-camera calibration.
View →ArucoTarget
Grid of independent ArUco markers, with no shared chessboard backing.
View →Detection Skills
Detect and Annotate
Detects ChArUco corners on an image and returns an annotated copy plus the corner count.
View →Object Points
Board-frame 3D coordinates of every inner corner of a ChessboardTarget.

Data Collection & Persistence
Drive a robot through a pose sweep and save or load calibration datasets with Axon.
