In addition to developing innovative hardware and sensor systems, it was necessary to develop a new software interface to assist the operator in viewing and analyzing the inspection data. Modern image processing techniques have been applied to the tasks of creating an augmented 3D virtual-reality reconstruction of the sewer pipe and for automatic detection of various types of damage.en670conference paper
