Maintaining them is not only a matter of heritage preservation but also a question of security. Inspecting tunnel canals is difficult and time consuming, which motivates the development of an image-based surveying system, as already exists for railway or road tunnels. However, while the imaging configuration is similar, referencing the data acquisition device is more difficult in the case of underground waterways, due to the drifts of the inspection barge. In this paper, we introduce the recording prototype we have designed and report the results of the test that were performed in an underground waterway, Niderviller's tunnel, to assess the feasibility of the system. In particular, we give details on the imaging system design. We also analyze the pros and cons of each location method, in terms of costs, practicability, computational burden and accuracy.
