Application of Location Information by Stereo Camera Images to Project Progress Monitoring

In this paper, the authors discussed the overview of a method for estimating the 3-D coordinated data for development of a project control system with stereo camera images. The information for control project with location information in the 3-dimensional space of time series from images is proposed. SFM (Structure From Motion) is used for collection of camera motion and 3-D object data. The image collection on actual construction site was performed and 3D structure from stereo camera images was evaluated. According to the result, the possibility of the monitoring and the factors necessary to development for practical were proposed.
