227 Study on measurement method of structural fracturing process using Image processing : Evaluation of measurement accuracy on 3D dynamic displacement

Abstract

This study has been examined the 3-dimensional measurement method for dynamic displacement of real scale test model on shake table tests. This system can measure 3-dimensional dynamic behavior of test model without any contact by applying an optical motion capture technique and image processing technique. The system therefore is the most suitable measurement system for an evaluation of complex 3-dimensional behavior of test model. This paper describes the dynamic measurement accuracy, the effectiveness of the proposed system from the results of shake table tests using the collapse building model and the inverted pendulum model.
