Method for measuring railway ballast particle migration of railway ballast track

The invention provides a method for measuring railway ballast particle migration of a railway ballast track, and relates to the technical field of railway ballast tracks, and the method comprises the following steps: at the starting moment of a measurement period, shooting a first image of a railway ballast through a camera; first pressure data are obtained through a plurality of pressure sensors, the plurality of pressure sensors are arranged in the y direction, a camera and the pressure sensors in the view range form measuring stations, and a plurality of measuring stations are arranged along the track; shooting a second image of the railway ballast through the camera at the end moment of the measurement period; obtaining second pressure data through a plurality of pressure sensors; according to the first image, the second image, the first pressure data and the second pressure data, obtaining a railway ballast particle migration score of each measurement site; and according to the railway ballast particle m
