APPARATUS FOR MEASURING DISPLACEMENT OF GROUND

摘要

The present invention relates to an apparatus to measure a displacement of the ground, comprising: a fixing member which fixates to an object of which displacement is to be measured; an angle displacement measuring unit having a first rotation angle sensor coupled to one side of the fixing member to be rotatable around a y-axis and a second rotation angle sensor coupled to be rotatable around a z-axis; and a length displacement measuring unit (300) coupled to one side of the angle displacement measuring unit to be movable along an x-axis, having a length variation sensor to measure a displacement of a length along the x-axis.
