舰船图像拼接是舰船图像处理领域的关键技术,为了降低舰船图像拼接误差,使拼接后的舰船图像更加完整,提出了基于互信息技术的舰船图像拼接方法。首先对当前舰船图像拼接研究现状进行分析,找到各种舰船图像拼接方法的缺陷,然后采集舰船图像,提取舰船图像拼接特征,最后基于互信息技术描述2幅舰船图像的相关性,进行舰船图像配准和拼接,并进行了舰船图像拼接仿真实验。结果表明,本文方法可以得到比较完整的舰船图像拼接结果,降低了舰船图像拼接误差,舰船图像拼接速度要快于对比方法 2倍以上,提高了舰船图像拼接效率,验证了本文方法的优越性。

Ship image mosaic is a key technology in the field of ship image processing.In order to reduce the error of ship image mosaic and make the mosaic image more complete,a method of ship image mosaic based on mutual information technology is proposed.Firstly,the current research status of ship image mosaic is analyzed,and the defects of various ship image mosaic methods are found.Then the ship image is collected and the feature of ship image mosaic is extracted.Finally,the correlation of two ship images is described based on mutual information technology,and the ship image registration and mosaic are carried out,and the ship image mosaic is carried out.Connect with the simulation experiment.The results show that this method can get a relatively complete result of ship image mosaic,reduce the error of ship image mosaic,and the speed of ship image mosaic is more than two times faster than that of contrast method,which improves the efficiency of ship image mosaic,and verifies the superiority of this method for ship image mosaic.
