In today 's modern society, which is complicated like society and has many incidents, when a missing person is found in a forest, a lot of Human Resource and equipment are put into the national park, and the huge cost and manpower for searching the missing person are needed. Recently, some local police have been cooperating with the private sector and have been helping to find people who are missing or who are in need by introducing drone with Camera for people who are missing. In particular, the elderly patients with dementia and children are often found dead when they miss the golden time for a certain period of time, so it is argued that the importance of introducing a drones for searching for missing persons capable of precise search using a drones is needed It is true. In this paper, functional classification of drones and police should be introduced as mission equipment when drones are selected for searching for missing persons. I would like to discuss the procedure of officially introducing missing drones as mission equipment through legal amendment. Especially, I would like to discuss how to maximize the utilization of artificial intelligence technology as the mission equipment by using the software (Deep Learning) to learn the mountain trail and the face of the missing person when installing the drones' high resolution camera. Through this paper, I hope that the police drones will be activated in the search of missing persons in the future police.
