The invention discloses a track irregularity measuring device and method based on laser contour scanning, and relates to the technical field of track traffic detection and photoelectric measurement. The device comprises a first laser contour sensor, a second laser contour sensor, a first adjustable mounting bracket, a second adjustable mounting bracket, a carrying platform, a first walking wheel,a second walking wheel, a third walking wheel, a fourth walking wheel, an encoder, a programmable controller and a computer, profile curve data of one side of the to-be-measured track is acquired through a first laser profile sensor, and profile curve data of the other side of the to-be-measured track is acquired through a second laser profile sensor; and the computer calculates the vertical trackirregularity of the to-be-measured track according to the profile curve data on the two sides and the moving distance of the carrying platform. The method is suitable for measuring the irregularity information of the reduced-scale track model.
