Recently, maintenance of structure is more important than past time. Displacement measurement for maintenance of structure will be very efficient method than any other measurement data. However displacement measurement is difficult, so there are many method to assume displacement In this paper, we study displacement measurement for estimate the structure condition on stress level.
