Title: TUNNEL INSPECTION SYSTEM COMPRISING INDIVIDUALLY DRIVEN RAIL-GUIDED VEHICLE AND INERTIA NAVIGATION SYSTEM
Abstract:
Provided is a tunnel inspection system for scanning the internal wall surface of a tunnel, comprising an individually driven rail-guided vehicle and an inertia navigation system (INS), the tunnel inspection system being capable of applying a separate driving device to each axle such that moving wheels on both sides can be independently driven, adjusting, through real-time speed control, a movement distance difference occurring on the left and rights, applying an electromotive lens to each camera, automatically adjusting a tilting angle, a magnification, a focal length, and an iris of each camera according to a tunnel shape having been ensured after a laser scan, installing the INS on each corner of a vehicle body of the tunnel inspection system, and measuring and recording changes in the vehicle body when the rail-guided vehicle moves so as to later reflect the recorded changes in the measurement data.
