System and method for early warning of railway slope abnormity

The invention discloses a system and a method for early warning of railway slope abnormity, and the method comprises the steps: obtaining a monitoring video stream of a target area, carrying out the motion detection frame by frame, and screening out a first abnormal target; using the trained neural network model to further identify the image containing the first abnormal target in the first information list, and screening out a second abnormal target; according to the image frame containing the first abnormal target in the first information list, whether the image frame containing the second abnormal target in the corresponding second image is larger than eight is judged, if yes, it is judged that the side slope abnormal target exists in the frame image, and first reporting is carried out. According to the invention, through multiple times of abnormal target identification based on different methods, dependence on high-definition images and computing power is avoided, meanwhile, good identification accuracy i
