基于Matlab的航道疏浚数据可视化研究

Matlab-based research on channel dredging data visualization

数据可视化是将多维数据以图形、图像方式显示,拓宽了传统图标的功能,提高了人们对数据的处理及解释能力,为更好地利用数据奠定了基础。从航道疏浚测试数据可视化需求出发,分析了基于Matlab的数据可视化方法,并以曹妃甸区海图为例,进行了以先进行定深挖再平挖的疏浚工艺数据可视化仿真。并讨论了如何利用VC++和数据库技术建立航道疏浚测试数据可视化管理高效、系统的方法,为快捷、准确、系统地对测试数据进行判断提供了方法。

Data visualization refers to display of multidimensional data in the form of graph and image , which can broaden the function of traditional icons , improve people's data processing and interpretation capacity , and lay the founda-tion for better use of data.Starting from the data visualization demand in the channel dredging test , the paper analyzes Mat-lab-based data visualization method , and describes related simulation for dredging process data of first deep-cut and then flat-digging with the nautical chart in Caofeidian District as an example.In addition, the paper discusses how to realize channeling dredging test data visualization management in high-efficient and systematic way using VC ++and database technology , providing ideas for rapid , accurate , and systematic judgment of test data.
