Drone technology has been used in various fields including personal hobby, pesticide application and shipping etc. However, only few drone technologies are used in restricted fields such as transportation of alimony goods and utilization of video because of the limited utilization aspect of disaster management field. Especially, disaster specialists' the lack of understanding of the drones seems to increase the difficulty of activating drone technology in disaster management. The theme of the thesis aims to share outline of drones' control method and education plan. This project also analysis the reasons why drone has not been used in disaster management with the fact that drone can be a vital part of emergency management. We propose improved application plan to use drone technology and future development direction in disaster management by deriving problems in terms of institutional aspects(regulation and education) and sensor-based application problems camera, thermal camera, infrared sensor, RFID.

Drones, which show strong growth in the fourth industry, are commonly used for disaster response. In the event of an actual disaster, local governments should carry out 13 cooperative functions to respond to the disaster, but there are difficulties in collecting on-site information in places where it is difficult for people to access or grasp the situation. Based on the 13 collaborative functions that are essential for operations in the event of a disaster, a utilization plan of highly utilized drones was derived. Through the analysis of overseas cases and drone utilization by each department, a total of 10 out of 13 collaborative functions of the Disaster and Safety Countermeasures Headquarters (disaster situation management, emergency life safety support, emergency recovery, disaster resource support, traffic measures, medical and quarantine services, disaster site environment maintenance, social order maintenance, search, rescue, and emergency) were derived. These results can enhance the efficiency of the disaster response by presenting a plan to utilize drone images for each function.

전주는 가장 한국적인 도시답게 모든 사적과 여 채가 있는 한옥마을의 건물이 모두 목재와 기와로 지어진 한옥으로 밀집되어 있어서 화재와 지진, 풍수해 시에 소방차나 구조차의 진입에 어려움이 있다. 이로 인해 초기 화재 진압 시간이 지연됨에 따라 인명피해와 함께 국보와 사적지가 전소될 수 있어 인명과 문화재 보전을 위해 소방시설의 확충과 안전관리가 절실하게 필요하다. 이에 재난 대비를 위한 방법으로 소방 드론을 활용하는 것이 최적의 방법이 될 수 있다. 본 논문에서는 메타버스 플랫폼인 로블록스를 활용하여 스마트시티-전주를 구현하였고, 소방드론을 활용할 수 있는 드론 소방서를 제안하였다.

최초에 군용으로 개발되었던 무인기(Unmanned Air Vehichle, 이하 드론)가, 최근 많은 연구를 통해 다양한 분야에 활용되고 있다. 본고에서는 다수의 드론을 통해 드론 편대를 구성하고, 이를 활용하여 무선 통신 네트워크 인프라를 구축하며, 재난 지역과 같은 무선 네트워크 접속이 불가능한 지역에 있는 사용자가 인터넷을 연결할 수 있게 해주는 Net-Drone을 제안한다. Net-Drone은 무인기간 유기적인 비행 정보 교환을 통해 드론 편대에 기반한 네트워크망 구축에 있어서의 안정성을 증강시키고, 드론 편대의 위치 정보를 중앙에서 관리하는 체계를 통해 최적의 라우팅 경로를 파악하여 지상의 네트워크 트래픽에 기반한 최상의 드론 배치를 설정한다. 본고에서는 Net-Drone의 물리적인 구현에서부터 사용자에게 네트워크를 공급하게 되는 전체 과정을 소개함으로써, 재난 지역 등의 네트워크가 연결되지 않은 지역에서의 무선 네트워크 인프라 구축에 대한 새로운 가능성을 제시한다.

The purpose of this study is to strengthen the capability of rapid mapping for disaster through improving the positioning accuracy of mapping and fusion of multi-sensing point cloud data derived from Unmanned Aerial Vehicles (UAVs) and disaster investigation vehicle. The positioning accuracy was evaluated for two procedures of drone mapping with Agisoft PhotoScan: 1) general geo-referencing by self-calibration, 2) proposed geo-referencing with optimized camera model by using fixed accurate Interior Orientation Parameters (IOPs) derived from indoor camera calibration test and bundle adjustment. The analysis result of positioning accuracy showed that positioning RMS error was improved 2~3 m to 0.11~0.28 m in horizontal and 2.85 m to 0.45 m in vertical accuracy, respectively. In addition, proposed data fusion approach of multi-sensing point cloud with the constraints of the height showed that the point matching error was greatly reduced under about 0.07 m. Accordingly, our proposed data fusion approach will enable us to generate effectively and timelinessly ortho-imagery and high-resolution three dimensional geographic data for national disaster management in the future.

In modern society, human and social damages caused by natural disasters and frequent disaster accidents have been increased year by year. Prompt access to dangerous disaster sites that are inaccessible or inaccessible using state-of-the-art Earth observation equipment such as satellites, drones, and survey robots, and timely collection and analysis of meaningful disaster information. It can play an important role in protecting people's property and life throughout the entire disaster management cycle, such as responding to disaster sites and establishing mid-to long-term recovery plans. This special issue introduces the National Disaster Management Research Institute (NDMI)'s disaster management technology that utilizes various Earth observation platforms, such as mobile survey vehicles equipped with close-range disaster site survey sensors, drones, and survey robots, as well as satellite technology, which is a tool of remote earth observation. Major research achievements include detection of damage from water disasters using Google Earth Engine, mid- and long-term time series observation, detection of reservoir water bodies using Sentinel-1 Synthetic Aperture Radar (SAR) images and artificial intelligence, analysis of resident movement patterns in case of forest fire disasters, and data analysis of disaster safety research. Efficient integrated management and utilization plan research results are summarized. In addition, research results on scientific investigation activities on the causes of disasters using drones and survey robots during the investigation of inaccessible and dangerous disaster sites were described.

The purpose of this study is to determine the rapid saving of life through the drones when natural disasters such as earthquake and fire occur. Drones are equipped with riders, temperature, hazardous gas sensors and wireless cameras are registered with the application server for monitoring the disaster site and real-time monitoring functions are performed to identify the situation on site before rescuing personnel are active. When monitoring finds a person to save, the application server provides real-time image information for effective life-saving.
