多波束探测技术在海底地形测量中的应用研究

Research on Application of Multi-beam Detection Technology in Subsea Topographic Survey

海底地形测量是海底资源开发和近海规划的重要环节,目前应用较多的是多波束探测技术,但由于传统追踪算法的限制,测量重叠区域误差数值通常在1 m以上。基于此,本文提出基于无迹卡尔曼滤波器的海底地形跟踪算法,并在渤海西侧、秦皇岛市北戴河区某海域进行原生海底对比研究,详细阐述多波束探测技术的安装方式、参数校正和本文算法的实现过程,最终验证使用本文算法能够将测量重叠区域误差数值控制在0.6 m以下,大幅度增强多波束探测技术的应用性能。

Subsea topographic survey is an important link of seabed resource development and offshore planning,at present,the multi-beam detection technology is more commonly used,but due to the limitations of traditional tracking algorithms,the area of measurement overlap error value is usually above 1m.Based on this,this paper presents a seabed terrain tracking algorithm based on a trace Kalman filter,and in the west side of the Bohai Sea,a sea area of Qinhuangdao Beidaihe District,the original seabed comparative study,the installation method,parameter correction and the algorithm in this paper,final validation uses the present algorithm to control the measurement overlap region error value below 0.6m,significatly enhance the application performance of multi-beam detection technology.
