Abstract
A method and a system for detecting railway foreign object intrusion, and a device and a medium can include acquiring a first key frame of railway image of a current scenario as a template image, and an Nframe of railway image as a to-be-detected image; inputting the template image and the to-be-detected image of the current scenario into a foreign object intrusion prediction model to obtain a foreign object feature map of the current scenario, so as to determine whether there is a different target between the to-be-detected image and the template image of the current scenario; and filtering, by using a moving object filter model, a moving object from the different target of the to-be-detected image of the current scenario in response to existing different target, to obtain a true foreign object in the to-be-detected image of the current scenario.
