Guide

Generate high-precision printable calibration targets for camera calibration and photogrammetry. Print at 100% / Actual size to preserve accurate measurements. For chessboards, inputs are inner corners (intersection points).

Target parameters

Chessboard configuration

OpenCV detects inner corners (intersection points), so printed squares = (rows + 1) × (cols + 1).
