Description

SEARCH METHOD AND SEARCH SYSTEM USING PROFILING TECHNIQUE AND DRONE}

The present invention relates to a search system, and more particularly, to a search method and system using a profiling technique and a drone.

Drones are vehicles that fly by remote control or autonomously fly along a designated route without a person on board, and have been mainly used for military purposes. Recently, they are used in various fields such as transportation and security. It is also being utilized.

The disappearance is that a person has lost his or her death and the life or death is unknown. It can be said that the disappearance occurred and caused legal/social problems. This disappearance is a factor that has devastated families and society. According to the National Assembly Legislative Survey (2013), "social costs of about 570 million won per person for long-term missing persons are incurred."

In particular, in the case of disappearance or distress in large areas such as mountains, valleys, and rivers, it is difficult to know the exact location of the missing person. There is a case of missing.

Helicopters or drones are used for the search for missing persons, but helicopters and drones cannot search for the missing persons themselves, and in particular, helicopters have a problem that costs about 20 times more than drones. In addition, in the case of a general search, there was a problem that a lot of time is consumed because the site terrain is analyzed and the moving line is predicted simply based on drone manipulation and subject information.
