Yet, the actual surveying has found many difficulties, if not impossible, in achieving the required accuracy taking into account the restricted as well as challenging environment inside the tunnels. The aim of this study is, based on the preliminary work, to advance the tunnel profile positioning quality using photogrammetric imaging and laser profile. The proposed methodology in data acquisition and computation platform would solve quality 3-D profile while a simulator would allow effective planning before actual field survey. They together constitute an efficient, high quality and flexible means for the task of 3-D tunnel profile positioning.攝影測量隧道雷射剖面模擬器PhotogrammetryTunnelLaser ProfileSimulator
