海洋测量船激光码头标校的论证与试验

THE TFST AND ARGUMBMTATION OF THE LASER WHARF CHECR OF THE OCEAN MEASUING SHIP

本文简要介绍激光码头标校方案,采用电子全站仪的极坐标法测定激光束首尾两点的坐标,来解算惯性导航平面倾角(θ、ψ)和航向角κ。文中对DIOR 3002测距仪无反光镜合作时的测距精度、电子全站仪的定点精度、电子全站仪之间同步测量、数据自动传输等作了详细的试验,得出了适合于激光码头标校最佳测量条件,为激光码头标校部分代替船坞标校提供了论证基础。

In this paper, a method of ship duck check , the coordinate system and the combination of 'Yuan Wang' measuring ship arebriefly introduced, pointed to deficiency of ship duck check, a way of the laser wharf check are put forward.Using the polar of coordinte of total station, the coordinte of the head ano the tail are measured to solve banking angle of the platform of navigation. In order to assure the precision of check, when the Prism is not used the procision of measuring distance for DIO R 3002 and the precision of deciding point for total station are tested. Finally, we obtain the best condition of measurement to suit the laser wharf check.
