摘　　要：雷达图像和电子海图是舰船航行的重要信息来源。针对雷达图像噪声多、孤立点多、目标被遮挡,导致其与电子海图匹配定位不准确的问题。将部分Hausdorff距离的匹配算法进行改进,应用于已提取海岸线边缘特征的雷达图像和电子海图的匹配定位中,通过α和β两个参数的设定,大大提高了匹配的精度,实现了航海保障中的实时准确定位。Radar image and electronic chart are the important sources of information for ship sailing.Now for the problems that radar image and electronic chart match not accurately because of the noise,isolated points,blocked targets.The matching algorithm of partial Hausdorff distance is improved,which is applied to the matching of the edge feature of the extracted coastline from radar image and the electronic chart.Through the setting of the two parameters,the accuracy of the matching is greatly improved,to achieve the maritime security in real-time accurate positioning.
