The embodiment of the invention provides a track irregularity detection method based on correlation statistical characterization and perception continuity. The method comprises the steps that operation parameters of an axle box of a running train are obtained; determining the vibration displacement of the running train; determining a moment sequence corresponding to the equal driving distance according to the fluted disc gear tooth moment data; resampling the vibration displacement according to the time sequence to obtain equidistant resampling data; performing median filtering on the equidistant resampling data based on a preset window length to determine smooth vibration displacement data; determining consistent vibration displacement characterization data according to the plurality of pieces of smooth vibration displacement data on the rails with the same position and the same length; calculating a first wavelength and a first wave depth of the track irregularity in the consistent vibration displacement characterization data; the first wavelengths and the first wave depths of a plurality of running trains on the track are obtained to obtain a first wavelength set and a first wave depth set, and a high-confidence irregularity detection result is obtained through standardization processing. The method is used for improving the track irregularity detection efficiency.
