Abstract

In order to detect the hazardous/impurity particle in the water, the developmental research for the monitoring system of spatial distribution of particle in the water has been carried out. In the research, the spatial distribution and the spatial behaviour of particle in the water is visualized by the laser sheet light illumination. The number of particle in each size has been counted by the analysis of the visualized image. The size distribution of particle has been displayed by the image analysis. In order to validate the technique, mono-dispersed Poly Styrene Latex (PSL) particles those are micron size are used. The correspondence between the particle size and the pixel area of each particle image has been obtained from the visualized images. Besides, the image analysis by the use of optical image processing has been trialed. In the technique, target particle that has specific size and/or shape can be detected in real time. Combining these techniques, specified particle's spatial distribution and the number can be monitored in real time in the water supply system

水中杂质颗粒空间分布监测系统的开发研究

为了检测水中有害杂质颗粒，开展了水中颗粒空间分布监测系统的开发研究。在研究中，利用激光片光照射，可视化了水中粒子的空间分布和空间行为。通过对可视化图像的分析，计算出了每种尺寸的颗粒数量。图像分析显示了颗粒的尺寸分布。为了验证该技术，使用了微米大小的单分散聚苯乙烯乳胶(PSL)颗粒。从可视化图像中得到了各颗粒图像的颗粒大小与像素面积的对应关系。此外，还对利用光学图像处理技术进行图像分析进行了试验。在该技术中，可以实时检测具有特定尺寸和/或形状的目标颗粒。结合这些技术，可以实时监测供水系统中特定颗粒的空间分布和数量
