3D Modeling from photogrammetry has been used widely in the construction industry for various purposes such as visualization, measurements, progress tracking, and productivity analysis. Photogrammetry is a challenging task especially for existing structures such as tunnels, roads, and bridges. It can be difficult to model dynamic sites such as tunnels which may be risky if photos have to be taken manually. Hence, this paper aims to investigate an approach for photogrammetry of dynamic sites. The investigated method is time-efficient, safer and provides an acceptable level of quality for 3D modeling.
