In recent years, the damage of the red tide that occurs during the summer season is high in the coastal waters. This is caused by marine pollution and ecosystem changes caused by the expansion of cultivating fishing, that is, conversion to aquaculture. These red tide occurs in an instant and flows in a band shape over the sea, causing great damage to farms. .

In order to reduce the damage caused by red tide, various control methods have been developed, and active damage relief activities are being carried out. However, for such a control, it is necessary to know exactly where the current red tide occurs and in what band shape and where it is flowing.

Accordingly, in order to accurately determine the location and the flow of the red tide, the related government agencies and local governments have mobilized dozens of ships to monitor the naked eye. There are many limitations such as the inaccuracy of and the narrowness of observation range by observation near sea level.

Of course, there are methods of using a satellite image and a method of using an aircraft. However, due to cost problems and operational difficulties, there have been problems in that the situation is limitedly used only in extremely serious cases.

On the other hand, the recent phenomena of whitening phenomena (dog recording) on the east coast and Jeju coastal area are not properly conducted. This bleaching phenomenon is a phenomenon in which the algae of the seabed are extinct and the lime algae are breeding and the seabed environment is changed like a desert. The situation is adversely affecting the environment.

A lot of research has been conducted to prevent such phenomena, but it is also difficult to properly respond due to the problem that the monitoring of the occurrence of birches is not carried out properly.

Conventional monitoring methods are mainly implemented by the method of visual confirmation of the diver, and some methods using an unmanned aerial vehicle have been proposed, but as described above, with the inaccuracy of visual confirmation and difficulty of limit of the monitoring range, the unmanned aerial vehicle Due to meteorological conditions and operational problems on the coast, such as the use of the light, effective monitoring is not achieved compared to the input cost.
