Dynamic compensation method and system for contact rail detection data during vehicle body vibration

The invention discloses a dynamic compensation method and system for contact rail detection data during vehicle body vibration, and the method comprises the steps: collecting a contour curve of a contact rail through a first laser contourgraph, and collecting a contour curve of a walking rail at the same side with the contact rail through a second laser contourgraph in the movement process of a detection vehicle; the contour curve of the walking rail is divided into a rail top section, a rail waist section and a rail bottom section; calculating an inclination compensation angle based on the rail waist and the rail bottom section and the standard profile curve; on the basis of the inclination compensation angle and the static calibration angles of the two laser contours, the contour curve of the contact rail, the contour curve of the walking rail and the horizontal distance and the vertical distance between the two laser contours are compensated and corrected; and calculating a pull-out value and a guide heigh
