基于MATLAB的海岸污染物浓度扩散实验分析

Experimental analysis of pollutant concentration diffusion in coast based on MATLAB

为了定量地研究物质输移扩散的重要特征,本文应用CCD摄像设备对海岸污染物扩散实验过程进行测量,利用MATLAB强大的图像处理功能,得到了分布良好的相对等浓度线和浓度中心线,通过对同组多个图片的相同处理可进一步得到浓度等值线随时间的变化过程及浓度变化趋势,较好地反映物质输移扩散的重要特征。本文的特色与创新在于基于MATLAB的海岸污染物图像分析方法程序简洁、效率高,克服了以往研究方法(采用C、C++、VB等语言)缺乏现成的图像处理模块、句子长、容易出错的缺点。

In order to study quantitatively the important characteristics of material transportation diffusion,the experimental process of the coastal pollutant diffusion through the CCD camera equipment was carried out using the powerful function of image processing by MATLAB.It can get the relative concentration contour and center line,and through the same process to different images in the same set,and it also can receive the variation process of the concentration contour versus time and the concentration variation tendency.It can preferably reflect the important characteristics of the material transportation diffusion.The characteristics and innovations of this paper are as follows： the analytical method of coastal pollutant images has the advantages of simple program and high efficiency,it can overcome the disadvantages of the existing research methods（C,C＋＋,VB languages）,such as lack relevant image processing module,long sentences and error prone.
