Safety management means that protect the life and property from natural disaster such as earthquake and abnormal climate etc. And also it is very important as the building structures are higher and more large scale structures. In this paper, various kind of technologies including fiber optic sensor application, image processing for detect the crack width are simply proposed. And also, the schematic system which can be applicable to the safety management of building and large scale structure are suggested. Related research project have performed by KICT since 2011, and this year is 2nd project period. As time goes on, the developing state of the arts will be presented in the future.
