Description

Technical Field [0001] The present invention relates to an underwater structure diagnostic imaging device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater structure diagnostic imaging apparatus, and more particularly, to an underwater structure diagnostic imaging apparatus capable of acquiring a clean underwater image of an underwater structure in an underwater environment with high turbidity.

As is well known, since underwater structures such as piers, banks, settlement prevention blocks, and take-off boats are composed of reinforcing bars and concrete, the outer walls of the structures are abraded and eroded by the erosive action such as river water having high strength, The supporting force and the strength of the container are drastically reduced.

In addition, excessive stress is generated in the vertical direction of the underwater structure due to the self weight of the underwater structure itself, resulting in detachment and loss of concrete, as well as corrosion of the rebar due to detachment of concrete in the underwater structure.

In addition, the underwater structure is partially damaged and damaged due to abrasion and erosion due to the flow velocity of stream water and vortex generated in the vicinity, so that deterioration of the underwater structure is inevitable as time passes.

Therefore, conventionally, in order to solve the above-mentioned problem,

And diagnose it quickly and accurately. In case of an error, we have carried out proper repair and reinforcement work for the branch.

A conventional diagnostic method for detecting the abnormality of an underwater structure in advance includes a method in which a diver is directly introduced into the water to photograph the underwater structure.

However, the above-described method has a limitation in that it is difficult to accurately determine the position where the diver is currently photographing in a highly turbid water even when the diver dives, and the accuracy of the obtained image is blurred .

As a result, in the case of a blurred image, the abrasion and erosion sites of the underwater structure can not be accurately displayed on the drawings, and it takes a considerable amount of time to accurately track the problematic parts and there is a problem that a technician can misjudge.
