Study of the Ship’s Deformation Relay Measurement Based on CCD

In the ship,some equipments need the attitude provided by the navigation apparatus.Because at the same time the error is brought on by the ship’s deformation existing between the equipments,the availability of the equipment decreasing is resulted in.The equipment measuring ship’s three-dimensional distortion is needed for the error corrected and the attitude improved.The ship’s deformation measurement technology based on CCD is the accurate measurement not needing contact. If the observation can’t be carried out between the equipments measured,the relay measurement is adopted.The principle and the model of the ship’s deformation relay measurement based on CCD are expatiated on in the paper.The simulated experiment is carried out.Validity of the ship’s deformation relay measurement is confirmed.
