Terrain Pretreatment for River Numerical Simulation Based on Image Processing
In order to improve terrain processing efficiency in the process of river numerical simulation, this paper took the part of Daliushu section of the Yellow River as the research object, used the image matching algorithm to get the accurate wide field channel image, used the mathematical morphology method to test the precise waterfront edge of channel image, imported the image into the AutoCAD graphics software, drew the outline of the natural channel and saves as*.dxf file, converted to*.kml file and loaded it into Google Earth , achieved real-time browse and demonstration of the river numerical simulation terrain.Experiment results show that terrain pretreatment for river numerical simulation based on image processing can improve terrain processing efficiency and precision in the process of river numerical simulation.
