动平台条件下基于全站仪的标校技术

舰船靠泊码头进行起降引导系统标校时,甲板处于晃动状态,架设在甲板上的全站仪无法满足置平要求,针对这一问题进行了动平台条件下基于全站仪的标校技术研究。首先,建立全站仪测量数学模型,以全站仪在动态条件下的测量数据为基础,将测量数据经空间几何运算后求得任意两目标点在甲板固连坐标系下的相对位置；其次,根据空间物体几何不变的性质,设计实验进行不同倾斜条件下的全站仪数据测量和相对位置偏差求解；最后,通过仿真分析了测量误差对相对位置平均偏差的影响。结果表明,全站仪在动平台条件下其测距、测角精度能满足标校要求。

Calibration Technology Based on Total Station Under the Condition of Shaking Platform

According to the situation that the total station instrument on the warship deck cannot be leveling, the measure.ment model is established under the condition of no leveling of total station instrument. Aiming at this problem, the calibra.tion technology based on total station under the condition of moving platform was studied. Firstly, the mathematical modelof total station instrument was established, then based on the measurement, data of total station instrument under dynamiccondition, the relative position of any two points in the deck fixed coordinate system could be obtained by measurement da.ta after the space geometry operation. Secondly, according to the geometric invariant property of space object, the experi.ment was designed to measure the data and calculate the relative position deviation. Finally, the influence of measurementerror on the relative position was analyzed by simulation. The results showed that the range and angle accuracy of the totalstation in the shaking platform could meet the requirements of the calibration.
