This paper shows the development of inspecting method about bridge without temporary scaffold, using and applying the optical measurement techniques about Unmanned Aerial Vehicle and Structure from Motion. In late years UAV and SfM progress innovatively, they are becoming common techniques. SfM is a technology for building a 3D model of the target structure only images taken from multiview. By using the UAV, it is possible to acquire an image from a view point which cannot be confirmed normally, it can be more effective inspection. Thereupon authors verified their techniques at the several bridges, and summarized the measurement range, photography method, measurement precision and investigation time for future use.
