THE SEDIMENT CONCENTRATION MEASUREMENT OF MIDDLE AND SMALL RIVER BASED ON WAVELET DENOISING ALGORITHM

ZHU Bing1,ZHOU Xu-yan1,PENG Xuan-ge1,KANG Xiu-hong2 (1.School of Information Science and Communication,Jinggangshan University,Ji’an,Jiangxi 343009,China;2.Ji’an Hydrological Bureau,Ji’an,Jiangxi 343000,China)  
Discusses the online inspection of the content of the river sediment in user of computer graphic processing technology.After using the submarine photograph method ingestion overflow cross section video information source material,carries on processing and the analysis using the wavelet denoising algorithm to the image,can measure the number of particles of sediment,sediment particle shape and size of each.Then we can get the total volume of sediment particles,the total weight and the weight of per unit volume of sediment,that is the sediment at the point of the rivers.This method is the computer image recognition technology and small river sediment monitoring technology combined organic,to achieve that accurate,dynamic,real-time,online tracking of the effects of river sediment sediment,opened the new way for the inspection of the content of the river sediment.
