Automatic river levee collapse monitoring method

Abstract

The invention provides an automatic river levee collapse monitoring method. The method comprises the following steps: 1, acquiring monitoring videos of multiple paths of monitoring equipment in real time, and performing preliminary screening on the monitoring videos by using a time sequence convolution dynamic change monitoring video frame detection model to acquire monitoring video clips possiblyhaving river levee collapse; 2, performing moving target detection on the obtained monitoring video clip by using a moving target detection model to obtain a moving target region image; performing semantic segmentation detection on the obtained monitoring video clip by using a river levee detection semantic segmentation model, and extracting a river levee region image; 3, performing image subtraction on the extracted river levee area and the obtained moving target area to obtain a river levee area image not containing the moving target; 4, creating a Gaussian filter, performing gray processing and Gaussian filtering on the obtained river levee area image without the moving target, and establishing a background template; and 5, finally, determining the collapse position and area by utilizing a frame difference method.

Description

technical field [0001] The invention relates to the field of video image processing technology and deep learning algorithm, in particular to an automatic monitoring method for river embankment collapse. Background technique [0002] The collapse of the river embankment refers to the fact that the river embankment is affected by factors such as river water immersion, wind and wave impact, water erosion, and alternation of dryness and wetness, which intensifies the weathering of the river embankment soil, reduces the erosion resistance, and is caused by the change of groundwater dynamic pressure caused by the fluctuation of the river water level. Unfavorable geological phenomena of reconstruction deformation such as erosion (abrasion), collapse (collapse), displacement, etc. of river embankments. The embankment collapse not only leads to the instability of the main channel of the river, but also destroys the embankment, threatens the embankment, and even breaks the embankment,...
