Abstract
For the vibrating testing of the building, there is a measurement experiment to investigate the effect of the object strain and displacement. There is a digital image correlation method as one of the techniques used in the experiment. This performs displacement measurement by image processing register the feature point of the measurement object as a template to track. Conventional methods had been registered in the template manually for all markers. This task becomes the cause of various human errors, such as time consuming, fatigue associated with monotonous work, hand shake due to the error, passed marker. Therefore, it is considered that these problems are solved by capturing the markers automatically. This study will devise a method for automatic detection.
