Abstract
The invention provides an image on-line sediment concentration measurement method of river sediment, comprising: sampling the image of river sediment, transferring the image, processing the image, calculating the sediment concentration based on the mathematical model. The features of the measurement method are: simple operation, convenient implementation, less labor intensity during sapling the image by the workman, continuous measurement and real-time detection of the sediment concentration, establishment of mathematics data and acquisition of sediment concentration data good for the timely prediction of the mountain land flood and drought in the future.
Description
Technical field
The present invention relates to a kind of method of measuring river silt sediment concentration, relate in particular to a kind of method of image on-line measurement of river silt sediment concentration.
Background technology
The distribution of silt content, diffusion, sedimentation etc. affect harbour, navigation channel and ecologic environment, so the measurement of silt content all is a very crucial problem to ecologic environment, ocean and offshore engineering research.For a long time, measure the method for river silt sediment concentration both at home and abroad, required measuring period is long, and testing process is loaded down with trivial details, hydrlolgic work personnel sampling process labour intensity is big, and be unfavorable for the continuous coverage of silt content data and detection in real time, still do not have a kind of good sediment charge measuring method so far.Current water level, flow have been realized on-line real time monitoring, but the monitoring of river silt sediment concentration also is in backward state, influence the on-line real time monitoring mountain area hydrology (water level, flow, silt content) the data intelligence speed of development, seriously hindered the timely prediction of mountain area flood, arid disaster.
Summary of the invention
The object of the present invention is to provide a kind of method of image on-line measurement of river silt sediment concentration, this method novelty, simple, can realize online in real time measurement river silt sediment concentration.
The present invention is achieved like this, and it is characterized in that the measuring process method is:
(1) river load image sampling: the diversion trench that will be fixed with capture equipment is put into the river, the river load of the diversion trench of flowing through is made a video recording take pictures;
(2) image transmits: by communication line with the image data transmission the photographed image acquisition and processing subsystem in the computing machine of control center;
(3) Flame Image Process: the multiple image processing methods such as morphological method that the image that obtains adopted Computer Image Processing software utilization edge enhancing, Threshold Segmentation, binarization processing of images and image, according to the technical standard of river load content, carry out signature analysis;
(4) according to signature analysis result and algorithm model, set up corresponding database,, reach host computer and manage and make a strategic decision according to the calculated with mathematical model silt content.
Capture equipment of the present invention is one or several video cameras, camera or camera composition.
Advantage of the present invention is: simple to operate, it is convenient to implement, little to staff's sampling process labour intensity, and the silt content data are carried out continuous coverage and detected in real time, database has been set up in data acquisition to silt content, is beneficial in the future the timely prediction to mountain area flood, arid disaster.
