Abstract: Image processing is applied to measurements of the soil for a tunnel model in centrifuge. For this aim a specifical device has been developed on the LCPC centrifuge (Nantes, France) and technics of digitalized image analysis and processing have been adopted so to measure with a good accuracy soil displacements in the vicinity of the tunnel face.
