Abstract
It is expected that 3D models derived from SfM (Structure from Motion) and MVS (Multi View Stereo) are applied for the efficient maintenance of civil engineering infrastructures. However, it may take a huge amount of time to generate appropriate models because the generation of 3D models requires know-how about shooting images and processing data. Therefore, in this paper, we proposed the method of generating 3D models easily and accurately by images that were taken without too much conscious of SfM. As a result of experiment, high accurate 3D models were obtained by our method about four times faster than by conventional method. Additionally, we presented the procedure and functions of analyzation that are effective for the maintenance of civil engineering infrastructures by time series 3D models and summarized that examples on a prototype system.
