This study has been doing research and development of 3-dimensional measurement method using the image processing technique for the measurement of dynamic displacement in shake table test. This measurement system is a very convenient system because it can measure the three-dimensional dynamic displacement in shake table test in which the several makers are only attached to the surface of an experimental structure. The system therefore is the most suitable measurement system for an evaluation of complex 3-dimensional behavior of experimental model. Fundamental hardware and software for the measurement system have been constructed until now. The fundamental dynamic measurement accuracy and effectiveness of the measurement system have been also confirmed from several shake table tests. This paper describes the dynamic measurement accuracy in shake table test in with the experimental model has several rotational behaviors, and also summarizes the synthetic performance of the proposed measurement system.
