  • CCTV는 다양한 목적을 위해 24시간 영상을 녹화하지만 현재 시스템으로 사각지대 없는 CCTV 시스템은 다수의 카메라를 설치하여만 한다. 최근 360도 CCTV의 등장으로 동시에 사각지대 없는 촬영이 가능하지만 아직은 해상도, 이미지 변환과 같은 기술적인 개선 연구가 지속적으로 보완되어야 하는 상황이다. 본 논문에서는 천정, 바닥, 벽에 부착된 360도 CCTV 촬영된 이미지를 안드로이드 모바일 기기에서 변환할 수 있는 앱을 개발하여 이동중에 촬영영상을 모니터링할 수 있도록 한다.

  • u-safety service system inter-works with the diverse operation agencies, through CCTV network, such as the emergency call terminal with built-in GPS, the mobile communication network, u-safety service provider, relay system and CCTV control center. In the case of the emergency call, this service searches the location of caller in real time, and then continues to search the location of caller through the control of CCTV in the searched place, and can provide the several agencies like guardian, police office, fire station, hospitals, relief organizations and municipalities, with the diverse information necessary for the secure rescue through SMS and wired network. In this paper, a new protocol and specification for u-safety service relay system is designed and implemented. The effectiveness of presented protocol is verified by computer simulation. The designed protocol of u-safety service is applied to real 3GPP and 3GPP2 mobile communication networks to verify its performance.

  • Mobile devices like iphone, ipad, kindle, and PDA are used as everyday tool. In the mobile environment, smart phones and other mobile units are also used as a tool for protection or infringement of personal information. Therefore, smart monitoring technology is required to protect personal information and privacy. On the other hand, with smart phones and the mobile environment, diverse application technologies are realized on hardware and software platforms. Therefore, this paper designs the network structure that forms privacy trust zone, and based on this, deals with the monitoring and monitoring prevention system with a focus on CCTV, through which this paper proposes a system that provides privacy trust zone information and its utilization which is capable of smart monitoring.

  • 본 연구는 제한된 특정 환경 내에서 실시간으로 로봇이 장애물을 감지하고 충돌 없이 목적지에 도달 할 수 있도록 하는 것을 목표로 한다. CCTV를 이용하여, 로봇과 내비게이션 서버만으로는 해결 할 수 없는 장애물을 실시간으로 감지할 수 있도록, 내비게이션 서버와 로봇 간에 통신을 최적화하기 위한 알고리즘을 개발하였다. 또한 내비게이션 서버는 어떤 로봇이 불특정 그리드에 먼저 도착해야 하는 지에 대한 데이터와 로봇의 상태를 나타내는 데이터, CCTV와의 상호작용을 통한 장애물 정보를 나타내는 장애물 맵을 유지함으로써 알고리즘의 완성도를 높였다. 이 연구는 제한된 특정 영역과 로봇의 최적화 배치 개수를 구하여 실제, 다양한 영역에서 사용할 수 있도록 구현하는 것을 목표로 한다.

  • CCTV는 사람들 생활에서 없어서는 안 되는 유용한 존재로 자리매김 했다. 가장 큰 장점은 범죄 수사과정에서 유전자나 지문감식에 견줄 만큼 기여도가 크다는 점이다. 폭력 및 범죄를 해결하는데 유용하게 쓰이고 있고 날로 발전하고 있는 상황이다. 본 연구에서는 최근 공간정보기술의 발달에 따라 여러 분야에 공간 정보 기반의 관제시스템이 운영 중이거나 추진 중에 있으며, 지능형 영상감시를 위한 동향과 CCTV 설치에 따른 합법성과 프라이버시 보호에 대해 연구를 한다.

  • Pedestrian traffic needs to be accurately quantified to predict effectively pedestrian traffic accidents, however, pedestrian traffic is more difficult to measure than vehicle traffic. In this study, we suggest the time-and cost-effective application of mobile closed-circuit television (CCTV) using a smartphone as an alternative that can collect and analyze real-time data with little. In the present investigation, the pedestrian-vehicle conflict that can develop into an accident was defined as the pedestrian accident exposure. After installing mobile CCTV in 40 sections of Dongseong-ro, Daegu, the pedestrian accident exposure was estimated through negative binomial regression analysis using the collected data. The results of the analysis showed statistically significant changes in the pedestrian accident exposure variables. Based on the present results, a pedestrian accident exposure estimation model was developed which can be used in sections where pedestrian accidents may occur.

  • As studies on ubiquitous computing are actively conducted, desire for various services, including image transmission storage, search and remote monitoring. has been expanding into mobile environment as well as to PCs. while CCTV (closed circuit TV) and un DVR (Digital video Recording) are used in places where security service such as intrusion detection system is required, these are high-end equipment. So it is not easy for ordinary users or household and small-sized companies to use them. Besides, they are difficult to be carried and camera solution for mobile device does not support high-quality function and provides low-definition of QVGA for picture quality. Therefore, in this study, design and implementation of embedded system of high-definition image transmission for ubiquitous mobile device which is not inferior to PC or DVR are described. To this end, usage of dedicated CPU for mobile device and design and implementation of MPEG-4 H/W CODEC also are examined. The implemented system showed excellent performance in mobile environment, in terms of speed, picture quality.

  • Machine learning techniques using visual data have high usability in fields of industry and service such as scene recognition, fault detection, security and user analysis. Among these, user analysis through the videos from CCTV is one of the practical way of using vision data. Also, many studies about lightweight artificial neural network have been published to increase high usability for mobile and embedded environment so far. In this study, we propose the network combining the object detection and classification for mobile graphic processing unit. This network detects pedestrian and face, classifies age and gender from detected face. Proposed network is constructed based on MobileNet, YOLOv2 and skip connection. Both detection and classification models are trained individually and combined as 2-stage structure. Also, attention mechanism is used to improve detection and classification ability. Nvidia Jetson Nano is used to run and evaluate the proposed system.

  • This research has been started with the goal of design and implementation of more innovative next generation security equipment system by understanding and reviewing the technological trend and status of security equipment system. The importance of environmental protection and management is ever increasing recently. Various types of equipment and system solutions are used according to the development of CCTV technology, but more efficient environmental protection and management are not in place because of situational restrictions such as expensive equipment and hard to install. Next generation security equipment system is designed and implemented to compensate and innovate these problem, and it is expected to utilize more effectively with lower cost through this research. In addition, methodology to inquire this system is proposed for security equipment system solution.
