多波束水深数据精度评估方法研究

Accuracy Assessment Method of Multi-beam Bathymetric Data

随着人类对海洋探索的深入,海洋测绘的重要性日益突出,能够进行条带式全覆盖测量的多波束测深系统,成为目前海洋测绘新技术的代表之一,其优越性得到了充分体现,但是多波束测深系统当前缺少成熟的精度评估模型。通过不同水深文件的比较,对相近点进行求差,实现了多波束水深精度的快速评估。

As human beings further explore the ocean,the importance of marine surveying becomes increasingly prominent.One of the most advanced marine surveying technology,multi-beam bathymetric system offers distinctive advantages with its strip-type full coverage measurement.However,the system is lack of accuracy assessment model.In this study,a quick assessment is achieved by comparing different bathymetric data and by computing difference between similar points.
