摘要

介绍了测量船船体变形测量系统几种测量方法的基本工作原理

比较了这几种测量方法的优缺点

在此基础上提出了一种新的测量方法-光栅法。该方法涉及的测量系统不仅体积小、质量轻

便于安装调试

而且精度也比较高

克服了前几种方法的不足。光栅法采用了图像高精度亚像素定位方法

可提高测量精度。对该方法的测量精度进行了理论分析与仿真试验

从理论误差和试验结果中

可得出结论:光栅法的测角精度可优于5″

能达到测量船船体变形测量系统的要求。

Abstract

Some methods metering instrumentation ship's hull deformation are generalized

and their advantages and disadvantages are compared. A new raster metering method is put forward

which not only has some advantages of small bulk

light weight and ease of installation

but also has higher precision. A high precision sub-pixel location technology is used in this approach and the precision of angle metering can be higher. Through theoretic analysis and practical experiment

the results show the precision of angle metering has excelled 5 arc second.
