| Abstract: |
The aim of this paper is a position image tracking analysis for reducing geometric displacement error in bridge deck wind tunnel test. When wind blow on the scaled bridge deck in wind tunnel test, traditional experiment method includes geometric error compared with extracting laser displacement transducer. DIC technique can be represented lateral and vertical displacement respectively with no interference each displacement factor. This paper includes template matching technique, geometric error, wind tunnel experimental test. at the result of wind tunnel test, lateral displacement error is increased according to increase wind force. |
