摘要
目前国内外对水中悬浮颗粒的检测一般采利用浊度仪或颗粒计数器,但随着时间的推移其灵敏度很容易下降.针对这一现状开发了一种用于水处理的数字图像处理技术,设计了相应的检测系统.通过对水体图像的采集、滤波、分割后,检测系统能很好地识别出水中的悬浮颗粒并作出统计,较好地解决了水处理过程中悬浮颗粒的检测问题.实验室模拟试验表明检测系统具有识别率高、灵敏度稳定等特点.
The common way of examination of suspended particals in water is using instruments such as a nephelometer,a grain counter etc,whose shortage is sensitivity decreasing with time. Focusing on this problem,the digital image processing technique including image collecting,filtering,and segmenting is used and the examination of the suspended particles is implemented. Simulation experiment results show that the examaination system has features of high identification rate and stable sensitivity.
