Flexible Measurement of Large Scale Column Structure's Centroid Based on Coordinate Measurement Equipment

A new measurement of large scale column structure's centroid with coordinate measurement system was designed. The measure principle, equipment and measure process of this new method were discussed, and then the measurement uncertainty was analyzed. The results showed that this method has a high precision especially for the large scale column structure. So this method not only has the merit of flexible but also has broad application and development prospect.
