Interpolation Method Applied to Dynamic Display of Debris Flow

This paper introduces a dynamic interpolation method for the three dimensional model of debris flow used in real time display,which is based on the principle of hydraulics,computational mathematics and kinematics of debris flow.The computer interpolation arithmetic is used to control the condition for moving points with the intrinsic characteristics of debris flow taken into account. Finally, the pair of images formed by two photogrammetries is inserted in the order of time so as to obtain the data for displaying the three dimensional animation.Four factors that influence the state of the flow are taken into account, and the problem of data sources when the body of debris flow is displayed on the computer has been solved.The digital model can restore the movement information of debris flow between two exposures of the photogrammetry and that makes dynamic display possible.
