Dynamic Calibration Method of Shipborne Photoelectric Theodolite
Aiming at the complex calibration process and strict calibration conditions of shipborne photoelectric theodolite ,a new calibration method for shipborne photoelectric theodolite was put forward. This method improves the spatial pointing accuracy by correcting the coordinate system conversion matrix between the photoelectric theodolite ,inertial navigation equipment ,and the ship through land calibration ,center line calibration ,and star calibration. This calibration method is easy to operate and can be carried out under ship dynamic conditions. It can effectively complete the calibration work of the pho-toelectric theodolite on the ship and improve the installation efficiency of the equipment. The actual installation results show that the real-time pointing accuracy of the shipborne photoelectric theodolite calibrated by this method is better than 20″.
