The Research Of Alum Control System In Precipitator Based On Digital Image Processing

With the quick development of software and hardware technology of computer, digital image processing has applied to all levels in industry territory, more and more embedded applications of it have taken place. However, there is some limitation in practice. There is still no one algorithm which can adapt to solve all problems. In fact, it is still a task of great challenge to solve special problems with special methods in practice.Based on digital image processing, a scheme of Alum Control System in precipitator of waterworks ,which include designing thinking, frame , measure and researching algorithms, is researched and exploited in the paper.The Alum Control System is made up of hardware and software, and the software consists of image collecting and processing. In the paper, image processing is the emphasis. According to the features of alum image, some features are abstracted which includes the density and texture. Because present arithmetic can't be used to get the perfect results, based on the thinking of Image Engineering, new arithmetic is brought forward and used in the paper. The results of experiments show that the arithmetic is effective, and the system is high effective and reliable.
