Abstract
The status of tunnel lining would indicate whether or not the tunnels under investigation are considered unsafe. Due to the diverse lining patterns and the scene situations, measuring tunnel linings faces rigorous restrictions in instrument selection, time efficiency and quality satisfaction. The focus on this study is to design a simulator that simulates lining data and acquisition through photogrammetric imaging with laser profile and perform as well as quantify profile positioning by adjustment approach. The simulator would provide photogrammetric network analysis, bundle adjustment and run time estimate so that a fulfilled quality and efficient operation flow can be planned and assured before an actual in-site surveying.
