Non-Invasive Calibration Of A Stewart Platform By Photogrammetry

This study introduces a novel forward kinematics-based calibration method for Stewart platforms using the Denavit-Hartenberg convention and a photogrammetry-driven error compensation strategy. Validated on the Tiger 66.1 platform, the approach employs high-resolution imaging and least-squares error correction to enhance pose accuracy without hardware modification, offering a non-invasive calibration solution extendable to other hexapod systems.
