CCD接力测量船体变形研究

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

在舰船上,不少设备需要导航仪器提供姿态信息,船体变形会引起设备之间的姿态传递误差,导致设备效用降低。为了修正误差,获得精确的设备姿态测量结果,需要一套测量装置对船体变形进行测量。基于CCD的船体变形测量具有非接触性、精度高的优点。但当测量的两设备安装基座之间光路不能通视时,需要采用接力测量方法。阐述了CCD接力测量船体变形方法的原理和模型,并进行了模拟试验。试验结果表明,CCD接力测量船体变形方法可以高精度测量设备之间的相对姿态变化量。

In the ship, some equipments need the attitude provided by the navigation apparatus. Because at the same time the erroris brought on by the ship＇s deformation existing between the equipments, the availability of the equipment decreasing is is brought on resulted in. The equipment measuring ship s three-dimensional distortion is rieeded 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 experia：ent is carried out. Validity of the ship＇s deformation relay measurement is confirmed.
