The invention discloses a dynamic compensation method and device for track geometric detection data. The method comprises the steps that steel rail profile images of steel rails on the two sides of a track before a detection vehicle passes and steel rail profile images of the steel rails when the detection vehicle passes are obtained; the steel rail profile images of the steel rails on the two sides of the rail before the detection vehicle passes and the steel rail profile images of the steel rails when the detection vehicle passes are compared and calculated, and the displacement amount and the inclination amount of the steel rails on the two sides of the rail when the detection vehicle passes are obtained; and the track geometric detection data is dynamically compensated according to the displacement amount and the inclination amount of the steel rails on the two sides of the track when the detection vehicle passes, so as to obtain compensated track geometric detection data. According to the method, quantit
