基于遥感图像技术的海上船舶识别技术在民用领域和军事领域发挥着非常重要的作用，如海上救援、交通管理和海上敌船监测等。随着遥感技术的不断发展，多光谱和高光谱遥感图像技术获得了广泛重视。本文介绍遥感多光谱图像技术的原理，分别从船舶遥感图像的降维技术、基于小波变换的图像融合技术等方面进行研究，能够显著提高海上船舶遥感图像的航行位置检测与估计。
Marine ship identification technology based on remote sensing image technology plays a very important role in civil and military fields, such as maritime rescue, traffic management and marine enemy ship monitoring. With the continuous development of remote sensing technology, multispectral and hyperspectral remote sensing image technology has received extensive attention. This paper introduces the principle of remote sensing multispectral image technology, from the dimension reduction technology of ship remote sensing image. Image fusion technology based on wavelet transform has been studied, which can significantly improve the navigation position detection and estimation of marine ship remote sensing images.
