Dam bank dangerous case video detection method and system based on real-time image edge enhancement

The invention relates to the technical field of dam bank dangerous case monitoring, in particular to a dam bank dangerous case video detection method and system based on real-time image edge enhancement, and the method comprises the steps: obtaining N monitoring images for monitoring a dam bank, carrying out the graying processing of each monitoring image, and obtaining the gray image of each monitoring image; respectively carrying out geometric transformation and difference filling processing on each gray level image to obtain each corrected gray level image; carrying out edge enhancement processing on each corrected grayscale image to obtain each edge feature enhanced image; performing fusion processing on each edge feature enhanced image to obtain a multi-scale fusion image; and matching the multi-scale fusion image with a historical image stored in a database, and determining a dangerous case level of the monitored dam bank according to a matching result. According to the method, the dangerous situation o
