一种针对侧扫声纳图像的数字镶嵌技术方法

摘要

以南海某海域实测侧扫声纳数据为例,研究侧扫声纳图像的数字镶嵌技术方法,对关键步骤进行详细的阐述.通过对原始侧扫声纳数据进行导航数据校正、海底线跟踪、斜距改正、TVG校正、船速校正、地理编码与重采样、拼接与镶嵌等处理,生成大区域、大范围、高分辨率、无缝拼接的侧扫声纳图像.实验结果证明声纳图像数字镶嵌技术的有效性,并取得理想的效果.%This paper proposes a digital mosaic method for side-scan images, taking the sonar data from the South China Sea as the example.The key steps of the method are analysed in detail.By the mean of a series of data preprocessing, it can create the high-resolution seamless mosaic sonar images.The experiment proves that it can obtain good effects for side-scan sonar images.
