| 摘 要： | 多波束声呐系统与侧扫声呐系统均为海底面探测的重要工具,二者均采用声学方法,在工作原理上存在异同。本文简要介绍了二者的研究进展,分别对其数据处理进行了比对分析,认为多波束声呐处理方法侧重于数据的测量精度,而侧扫声呐则主要侧重于图像处理;归纳了当前二者主要的数据匹配融合方法,包括同名特征融合、基于SURF算法的匹配融合以及特征点融合,从数据采集原理上对数据融合方法进行了深入分析,发现在探头定位、单ping数据点分布以及ping之间的数据定位上存在一定的困难,即使经过一定的处理,二者采集的也非简单的平面图像,故二者的数据融合尚存在一定的难度。

Research Overview on Multi-beam and Side-scan Sonar Data Fusion |
| |
| Abstract: | Multi‐beam sonar system and side‐scan sonar system are two important tools for the exploration of seabed .Both of them use acoustic method and there are similarities and differ‐ences in their working principle .Their research progress is briefly introduced and the data pro‐cessing of the two systems is compared and analyzed .It has been recognized that the data pro‐cessing of multi‐beam sonar system focuses on the accuracy of data measurement ,w hereas the data processing of side‐scan sonar is mainly emphasized particularly on the image processing . The main methods for the data matching and fusing used currently between the two systems are summarized ,which include the feature fusion of the same name ,the matching fusion based on the SURF algorithm and the characters fusion .From the principle of data acquisition ,the data fusion methods are deeply analyzed .It is found that there exist some difficulties in the po‐sitioning of detector ,the distribution of single Ping data point and the data positioning between the Pings .Even after a certain treatment ,what collected by the two systems are not simple planar images .Thus ,there are still some difficulties in the data fusion of the two systems . |
