A system for measuring a vehicle gap or a step, wherein a vehicle body to which a hood, a door, and a trunk lid are assembled is seated on a carrier and moved along transfer lines, and the system is installed over the transfer lines to measure a gap or step between the vehicle body, the hood, the door, and/or the trunk lid, the system comprising:

  • one or more door regulating units configured to place the door installed in the vehicle body such that they are freely rotatable to a reference position and attached between the vehicle body and the door and/or between front and rear doors to eliminate a gap or a step with respect to a pre-set portion of the door;

    upper rails installed in both sides above a workplace such that they correspond to the transfer lines;

    a moving frame configured to be movable below the respective upper rails;

    a forward/backward moving unit installed above the moving frame and moving the moving frame forwardly and backwardly on the upper rails;

    a horizontal moving unit moving installation frames configured to be substantially perpendicular at both end portions in a length direction of the moving frame to left and right in a width direction of the vehicle body on the moving frame;

    a vertical moving unit installed in the installation frames and reciprocally moving a sliding plate upwardly and downwardly in a height direction of the vehicle body;

    a measurement module installed to be movable upwardly and downwardly in the height direction of the vehicle body through the sliding plate of the vertical moving unit and configured to be rotatable on the basis of a forward/backward direction, horizontal direction, and vertical direction of the vehicle body to measure the gap or the step between the vehicle body and the hood, the door, and/or the trunk lid; and
