基于变形测量的舰船航向标校方法

A Method of Ship Course Calibration Based on Deformation Measurement

为了解决目前航向标校中的船体变形无法克服和采样时间不同步的问题,根据单摄像机三维姿态测量原理,通过若干台摄像机经过多层甲板的传递测量,最后综合各级接力站测量的结果可以得到安装在甲板层艏艉线上的参考物相对于安装在导航平台上的摄像机系统的姿态角,从而减小船体变形对航向标校的影响。并利用软件定时器进行同步录取解决读数时间不同步问题。通过理论分析表明,该方法可有效的提高测量精度,并可拓展使用到所有基座不通视的被试武器系统和测量设备之间的三维姿态测量。

For solve the problem that ship deformation can＇t be conquered and sampling instant can＇t synchronize of course calibration, using several separate camera to transfer surveying through many layer decks, analyse and synthetize the result of each relay station, and therefore it can calculate the attitude angle of reference object on the central line of the main deck relative to camera on the inertial platform, therefore it can decrease influence that ship deformation relative to course calibration. In this paper, The method can improve accuracy in theory , which suits to enlarge range in practice, such as 3d attitude measurement that benchmark and attitude information of user＇s and the scalar of ship＇s deformation caused by that couldn＇t see through with each other.
