多波束测深的异常数据编辑技术和实现

Multibeam echo sounding data editing and realizing

因为海况、仪器噪声、海水中浮游生物等因素存在,测深数据中含有大量的异常数据和噪声,由于数据量大,如何有效定位异常数据和噪声是目前国际上的研究热点。本文详细介绍了手工交互式编辑和常用的几种自动编辑方法,并重点介绍了基于测点密度的图像滤波方法,阐述了多波束测深数据编辑软件的实现,对多波束测深数据的快速编辑有一定的参考意义。

Because of device noises, bad sea state or incorrect ship parameter etc. , multibeam bathymetry data easily conceal many outliers. It is an international research hot about how to remove them. In this paper, we introduce traditional interactive editing mode and several kinds of automatic editing methods, and stress the image filter based on the density of bathymetric points. Finally, we discuss the realization of editing tool for muhibeam outliers. It can provide a reference for rapidly filtering outliers and developing corresponding tool.
