DESCRIPTION:As the maritime traffic increases\, maritime accidents are on t
 he rise. Drones are being used to detect distressed vessels quickly in the
  open ocean. The current system does not have a plan to operate drones acc
 ording to the search target\, which means it is inefficiently operated and
  the search time is delayed\, reducing the chance of survival. The operati
 on plan should be developed based on tests in various environments and con
 ditions. However\, real-world implementations of distress situations have 
 limitations. In the real world\, implementing human distress in the ocean 
 is limited by safety issues.\nIn order to find the optimal way to operate 
 the drone for marine search and rescue\, this study aims to construct a si
 mulation environment with various environments and conditions.\nTo realize
  the simulation environment\, Unity Engine was used. The environmental asp
 ects of the simulation include the sea (sea colour\, wave height)\, object
 s (vessels\, people\, etc.)\, and the environment (day\, night\, sunny\, r
 ain\, snow\, fog\, etc.). In terms of functionality\, camera angles can be
  set\, and adding a drone function allows the drone to move and shoot. In 
 this paper\, the environment factor was fixed to daytime clear weather\, a
 nd the focus was on the object to be searched. The simulation was develope
 d with five types of distress vessels (2-tonne fishing vessel\, 5-tonne fi
 shing vessel\, cargo vessel\, passenger vessel\, and motorboat) and six ty
 pes of distressed persons (baby\, adult\, and with or without life jackets
 ). The distress vessels can be set to sink\, capsize\, or drift\, and the 
 distress persons are drifting on the surface of the water. The altitude of
  the drone was limited to a maximum of 150m to comply with Korean law\, an
 d the camera angle could be set to (-30︒\, -45︒\, -60︒\, -90︒). To
  reflect real-world coordinates\, Cesium was integrated into Unity to simu
 late a marine environment. To do this\, Cesium's coordinate system was ada
 pted to be compatible with Unity's coordinate system\, and the positions o
 f the distressed person and the marine police in the distress scenario wer
 e expressed in terms of actual Earth longitude\, latitude\, and height. Th
 is maintains the scale and realism of the simulation environment.\nIt is e
 xpected that future simulation results will be used to develop a drone ope
 ration plan to effectively search for various distress ships and distresse
 d person to minimize human casualties.
