| 摘要 |
The present invention relates to a lattice type 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 coupled to one side of the angle displacement measuring unit to be movable along an x-axis and has a length variation sensor to measure a displacement of a length along the x-axis wherein the fixing member, the angle displacement measuring unit, and a location displacement measuring unit are repeatedly coupled to each other to be arranged in a lattice shape as a whole, and allow to accurately measure displacement of a structure, thus accurately identifying safety of the structure. |
