Railway foreign matter alarm method, device and equipment and storage medium

The invention relates to a railway foreign matter alarm method, device and equipment and a storage medium, and relates to the technical field of image processing. The method comprises the following steps: acquiring a to-be-detected image including a railway; according to the to-be-detected image and the semantic segmentation model, determining a to-be-detected region including a railway in the to-be-detected image; under the condition that the number of the to-be-detected area is one, whether a target foreign matter exists in the to-be-detected area or not is judged according to the to-be-detected image and a foreign matter classification model; the foreign matter classification model is used for detecting a preset type of foreign matter in the to-be-detected image, and the type of the target foreign matter is a type except a train in the preset type; and giving an alarm under the condition that the target foreign matter exists in the to-be-detected area. The method is used for improving the accuracy of railw
