  Abstract

In this paper, we establish measurement methods of vibration frequency for three-dimensional behavior measurement of large-scale structure using laser and high-speed CCD camera We project the diode laser having a smaller fluctuation on the object plane attached to the structure and measure the displacement of the structure using a precise relative measurement algorithm When we use high-speed (120 frames/sec) CCD camera, we can measure the vibration frequency having the uncertainly within 0.5％ by taking FFT on the displacement, from 0㎐ to 40㎐ And we also confirm the reliability and economical saving of the suggested measurement method of vibration frequency of the structure by showing the accuracy of displacement measurement using laser is comparable to that of relative positioning methods using GPS.
