Keywords:3D measurement, Laser Scanner, SfM, Bridge inspection

In fiscal 2016, the Ministry of Land, Infrastructure, Transport and Tourism introduced i-Construction, a new standard that assumes informationization, in all processes from surveying and design to construction, construction, and management, in order to improve the productivity of construction sites. In this study, we focus on the performance of 3D laser scanners and SfM, and consider the establishment of a new inspection method for bridge inspection, and a method for utilizing 3D data more, and to verify the measurement accuracy.
