Underground structure inspection system and method

Abstract

A system for inspecting an underground structure and a method of inspecting an underground structure, for example a shaft, tunnel or excavation, is provided. The system comprises a memory configured to store a plurality of images captured whilst moving along a predetermined path through the underground structure, a position determination module configured to generate position data associating each of the stored images with a position on the predetermined path, and a user terminal configured to receive a user input specifying a position on the predetermined path and to display at least one of the stored images corresponding to the specified position based on the position data. Accordingly, the user may retrieve and inspect images of the underground structure, based on the position at which the image was captured therein.
