Developement of auto extract system in a structure crack by digital image

수치영상에 의한 구조물 균열 자동추출시스템 개발

A crack in concrete structure gives trouble to safety of building and human life. This study gives that development of auto extract system in a structure crack by digital image impersonal method for extract structure crack. This system will be possible to impersonal measurement for old concrete building and structure. For this auto extract system, used geometry of high resolution digital image and crack line extract by relation based image matching method. Now to conclude, this auto extract system gives a method that a quick measurement of building crack, hold objectivity in result, makes standardization for acquirement data, optimization result of measurement.
