基于MATLAB建立示踪剂浓度的数字图像处理系统, 对示踪剂浓度图像进行数字化处理, 以便研究复杂岸坡水体中示踪剂的扩散规律. 在立面二维槽中槽复杂岸坡断面角形域排放的扩散实验过程中, 使用数码相机记录示踪剂浓度扩散的一系列瞬时图像, 对示踪剂扩散区域进行处理提取; 再根据比色(皿) 标定实验把灰度值转化为对应的浓度值, 使示踪剂的扩散图像以等浓度线图的形式显示, 实现了浓度分布数据读取的可视化. 结果表明, 基于MATLAB数学工具建立的示踪剂浓度的数字图像处理系统, 对研究水体中扩散实验的示踪剂浓度场是可行的.

The digital image processing technology oftracer concentrationmodel was based on MATLAB. Tracer concentration images in the diffusing test were dealt with a digital processing to study the concentration distribution in the water body of complex-bank. A series of instantaneous images were taken by a digital camera after the tracer was discharged into vertical two-dimensi-onal complex-tank during the distribution experiment. Next, the area of tracer diffusion was extra-cted, and the gray value was converted to corresponding concentration according to colorimetric calibration experiment. After these steps, the isoline map was established and the visualization of the tracer concentration gradient was realized. The results indicated that it was effective to investigate tracer concentration diffusion through this digital image processing technology based on MATLAB.
