| 摘 要: 水质管理信息化的需求日益增加,但水体数据的繁杂多样为高效管理水质数据带来了不便。针对这种情 况,设计了一种可以快速将水体的各类复杂数据及其间的数据关系进行可视化表达的算法。根据水质仪采集少量的样本 点,分别生成水体水平面、底面和中间部分的大量散点,描绘出水体的形状。然后计算每一个散点对应的水质数据,按 照水质数据对散点进行颜色渲染,通过不同的颜色表现出水质状况。最后借助ECharts在Web页面上进行水体数据可视 化展示。实验结果表明,该算法可以直观、快速地表现水体的各类数据,帮助对水体的水质进行网络化、科学、直观的 分析。 |

| Abstract: With the ever-increasing demand for the information-based water quality management, a visualization algorithm, which can quickly display various kinds of water quality data and their relationship is proposed. The proposed algorithm can grapple with the inconvenience caused by the complicated water body data. The algorithm deals with a large number of water data points that are collected by water quality instrument. The water data points are scattered in many places such as at different water levels, surface, bottom or middle parts respectively. These water data points describe shapes of the water body. Then the water quality of each scatter water point is indicated by using different colors. Finally, ECharts are used to visualize the water data on web page. The experimental results show that the algorithm can express all kinds of water qualities directly and quickly, realizing the web-based, scienti c and direct analysis of water quality. |
