On the basis of laser displacement sense principle, one non-contact rail surface sense measuring program is designed. Surface measuring instrument is made. Inspection and measuring for the single-section of rail surface are carried on and data-based image formation is given. The precise measuring is realized for rail surface, especial trail parts; By using the stepper motor diving technique and program operating imagine formation technique, combining the MTLAB programming, the single-surface measurement data is transformed into image and the dynamic measuring for rail vertical smoothing is achieved. By comparing to the standard data, the rail wear state and surface parameters are concluded .This technique met with the needs of non-touch automatic measuring for rail surface.
