极地海洋多波束测量测线布设系统设计及实现

Design and realization of line layout system for marine multi-beam bathymetric survey

针对目前多波束测量缺少专门的测线布设软件问题,考虑极地海域海冰对多波束测量的影响,本文设计并实现了极地海洋多波束测量测线布设系统。首先针对航前与现场作业等场景,设计了系统技术路线、架构和主要功能,特色功能包括建议测线方向计算、测线自动与手动生成、多波束现场处理数据导入和结果可视化评价等。阐述了系统功能实现的关键技术,包括测线自动生成、条幅制作与信息统计等。系统采用Py⁃thon语言以及第三方开源工具包开发,最后开展不同场景下的应用试验并对结果进行了讨论。试验结果表明,系统可以快速、方便地进行多波束测量测线布设并对布设结果进行评价,能够有效提高多波束测量方案的设计效率,有利于极地海底地形地貌调查工作的开展。

In view of the impact of the lack of software for survey line layout and sea ice on multi-beam bathymetric surveys in the polar ocean,we designed and implemented a line layout system for the multi-beam surveys.First,aimed at scenes before and during the survey,we designed the system's technical route,architecture and main functions.The features include calculation of line direction recommendation,automatic and manual line design,import of multi-beam on-site processed data,result in visual evaluation,etc.We elaborated on the key technologies to implement the system,including automatic line generation,swath production and information statistics.The system was developed in the Python language with some third-party open-source libraries.Finally,we conducted application experiments and discussed the results.The results show that the system can quickly and conveniently carry out line layout for multi-beam survey and evaluation of the results,which can effectively improve the efficiency of scheme design for multi-beam bathymetric survey,and is conducive to the development of a topographic and geomorphological survey of the polar seafloor.
