Remote visual inspection (RVI) is a non-destructive testing (NDT) technique for visual observation of a component or region under test where the inspector or technician operates the test equipment from elsewhere. Pan, tilt and zoom (PTZ) cameras have evolved to a more compact size in order to access extremely confined spaces. Software developments have enabled objective data to be viewed on screen, recorded for analysis and reporting later. Continued advancements in the field of robotics has empowered inspection cameras to travel into previously inaccessible areas. RVI is used to examine a wide range of infrastructure. When utilized as a standalone tool or part of a remote crawler system, RVI cameras can deliver high definition video with advanced imaging options for detailed assessment of any industrial structure with limited or unsafe access.
