This study has been examined about a 3-dimensional measurement method suitable for a fracturing test of real scale model using shake table test, and has proposed the measurement system using image processing. Although this measurement system is based on a simple theory of measurement, it is a very convenient system which only requires to install the markers on the object structure and it can be considered as the most suitable measurement system to evaluate the complex 3-dimensional behavior of real scale structure. Fundamental hardware and software in measurement system has been constructed until now. Moreover, the fundamental dynamic measurement accuracy and effectiveness of the proposed measurement system has been confirmed from the shake table tests using the 5-storey building model in elastic region. This paper describes the dynamic measurement accuracy, the effectiveness of the proposed system and the evaluation for practical use from the results of shake table tests using the collapse building model and the wooden house model.
