有色示踪剂在溶质运移实验中的数字图像识别和处理

Understanding and treatment of digital images of dye tracers in solute transport experiments

文章介绍了不同浓度高锰酸钾溶液的数字图像RGB识别方法,并将此方法运用到标准砂介质中高锰酸钾溶液浓度的拟合识别。在实验后期,提出了用高斯模板进行数字图像平滑处理来获得更精确的实验数据。本实验为砂柱溶质运移实验提供了一种简便而有效的溶质浓度测量方法。

The method of digital image understanding of KMnO4 solutions with different concentrations is introduced in this paper. It is used to the understanding of KMnO4 solutions in the media of standard sand. This method is cheaper and easier compared to the other kinds of solute transport experiments. Gaussian template is used to smooth the digital images in order to get better accuracy. This experiment provides an easy and effective method of concentration measurement for the column transport experiment.
