The online hydrological sediment detection system based on image process

We propose the online hydrological sediment detection system based on image process. It consists of image collection subsystem, signal transport processing subsystem, network transmission subsystem and ARM-based processing subsystem based on PXA270 processor. The system's configuration and structure is described. The system gets the image of mountain rivers flow section by using on-line technique and then proceed to hydrological analysis of sediment by the appropriate image algorithm. The multi-direction one-dimensional wavelet transformation microscopic image denoising algorithm. The experiment show that hydrological sediment detection system could get the sediment hydrological of mountain rivers flow on-line.
