【摘要】：利用数字图像处理技术是当前研究环境污染物扩散机理的重要手段。该文通过水槽实验,分析了污染物图像的灰度与污染物的浓度、光源的距离以及排放口所在水深的关系,并建立了污染物浓度与图像灰度关系的方程。利用该方程对射流在横流中测量的图像进行了浓度场计算,得到的结果与实际情况吻合较好,因此,该方法能广泛应用于物质扩散机理的研究。
[Abstract]:Digital image processing is an important method to study the diffusion mechanism of environmental pollutants. In this paper, the relationship between the gray scale of the pollutant image and the concentration of the pollutant, the distance of the light source and the water depth of the discharge port is analyzed through the flume experiment, and the equation of the relationship between the concentration of the pollutant and the gray level of the image is established. By using the equation, the concentration field of the image measured by the jet in the crossflow is calculated, and the results are in good agreement with the actual situation. Therefore, the method can be widely used in the study of the diffusion mechanism of matter.
