The present invention relates to a 3D measurement device having an auto-offset function. The present invention comprises: a plurality of displacement sensors transmitting signals corresponding to soil displacement after measuring soil displacement, installed underground or installed along a curved surface of soil and a tunnel apart from soil containing the tunnel; a program chip transmitting signals of change values after comparing the initial value of the displacement sensor and a current value, combined to each displacement sensor; and a control member controlling the transmitted value transmitted from the program chip on a display unit, connected to the program chip. The result value can be reliable since no one can improperly operate the present invention. Also, only the changed value between the initial value and current value can be displayed, displacement changes can be checked automatically based on the time set, displacement changes can be checked automatically more specifically if there are bigger displacement changes than set change value, and measured value can be stored. |
