基于点模式的雷达与电子海图信息匹配定位

Radar's and Electronic Chart's Information Matching and Locating Based on Point-pattern

为了实现雷达定位自动化,减轻航海人员的定位劳动,提高航行的安全性,采用点模式匹配方法,进行了电子海图和雷达信息匹配定位研究.论述了点模式匹配原理,雷达回波图像特征点集和电子海图图象特征点集的建立方法,特征点集匹配集的确定和平差求最或然船位的方法.通过示例验证了研究的可行性及在各种定位条件下的定位准确性.

In order to achieve the automatization of radar locating,lighten voyagers＇ labour,and enhance the security of voyage,this paper adopts point-pattern matching which is a kind of vision matching,to carry out the research of radar＇s and electronic chart＇s information matching and locating.It introduces the principle of point-pattern,the methods of setting up radar＇s and electronic chart＇s feature point set,and the way to confirm the matching feature point set and calculate the most probable ship position by adjustment.Through a lot of experimentation,it validate this research＇s feasibility and veracity in all kinds of locating conditions.
