Test measuring system of riverbank lateral erosion collapse rate and measuring method thereof
The invention provides a test measuring system of a riverbank lateral erosion collapse rate. The test measuring system comprises a tracing grid on a riverbank model, a shooting device and an image processing system. The shooting range of the shooting device covers the tracing grid on the riverbank model. The shooting device is connected with an image processing system. The method comprises the steps of: carrying out uniform grid marking on an upstream face bank slope of a riverbank lateral erosion collapse model, and forming an equal-interval tracing grid; in the test process, carrying out image collection through a high-precision camera; by means of binary image segmentation and digital image processing, extracting position coordinates of grid nodes of a newest bank line after lateral erosion collapse of a riverbank; carrying out coordinate conversion, comparing the position coordinates of the newest bank line with position coordinates of an initial bank line, and calculating a riverbank lateral erosion collapse distance; and then dividing the riverbank lateral erosion collapse distance by a time interval, and obtaining the riverbank lateral erosion collapse rate. According to the invention, measured data is accurate, and a technical support is effectively provided for deep research of a riverbank lateral erosion collapse mechanical mechanism and a forecasting method thereof.
