1. A measuring apparatus for measuring a relative distance (L) between two different points (A and B), the measuring apparatus comprising:

  • a first body having a first indicator for indicating a first direction;

    a second body having a second indicator for indicating a second direction and rotating relative to the first body;

    a first distance measurement module fixed to the first indicator in the first direction, which the first indicator indicates;

    a second distance measurement module fixed to the second indicator in the second direction, which the second indicator indicates;

    a rotation angle sensing means detecting a rotation angle between the first and second indicators;

    a controller receiving the rotation angle detected by the rotation angle sensing means, a direct distance (L1) to the point (A) measured by the first distance measurement module, and a direct distance (L2) to the point (B) measured by the second distance measurement module, and calculating the relative distance (L); and

    a display displaying the relative distance (L) calculated by the controller.
