Abstract:
본 발명은 비전 센서로부터 획득된 영상 및 이미지를 기 구축된 데이터베이스와 비교 분석 후 최초 이미지 획득 지점과 목표 지점의 거리를 산출할 수 있는 방법이다. 데이터베이스는 비전 센서를 이용하여 각 공간의 영상 및 이미지 정보를 저장하고 있다. 거리 산출 방법은 사용자가 전송한 영상 및 이미지 내의 물체 특징들을 추출 후 분석하여 데이터베이스와 비교를 통해 해당 이미지와 가장 유사한 이미지를 데이터베이스에서 확인하여 사용자 간의 거리를 계산할 수 있다.
Abstract:
A method for determining a base station for position determination and a method therefor using the same are provided to determine a base station for position determination accurately by determining a base station in consideration of arrangement of the base station and allow the mobile terminal to perform the more exact determination. A candidate base station which generates RSS(Received Signal Strength) more than the fixed critical value are determined(S400). Determined candidate base stations are grouped(S410). One or more group in which the mobile terminal is positioned within the triangle which the first, and the second and the third group element form is detected(S420). The group elements of the second group having the shape that it is most near to the regular triangle is determined as the base stations for the determination(S430).
Abstract:
A method for determining position of a mobile station is provided to reduce infra structure cost and improve accuracy by determining the position of the mobile terminal based on various medium. A method for determining position of mobile station is comprised of steps: requesting the position information to each medium and receiving the information and response time(S410~S424); estimating distance from each medium based on time of transmitting and receiving and processing(S440); measuring the location of the mobile terminal based on the presumed distance(450). In the device, various medium include at least one WLAN(wireless local area network) AP(Access Poont) or WPAN.
Abstract:
A position measuring system and a measuring method using interlocking between a GPS(Global Positioning System) and a UWB(Ultra-WideBand) are provided to recognize the location of a shadow region where a UWB signal transmitted from a GPS/UWB AP(Access Point) does not reach. A position measuring system is composed of an AP position decision part; a GPS/UWB AP(10) having three UWB transmitting and receiving units and three UWB position decision parts; and plural UWB modules(20-1,20-2,20-3). The AP position decision part calculates the position of the GPS/UWB AP by using a GPS signal. If a terminal is positioned in a communication region of three UWB transmitting and receiving units, each UWB transmitting and receiving unit calculates the distance to the terminal and outputs the calculated distance. If the terminal is not in the communication region of three UWB transmitting and receiving units, three UWB transmitting and receiving units receive the distance between each UWB module and the terminal from three UWB modules directly communicating with the terminal, and output the received distance. The UWB position decision part calculates the relative position of the terminal from the distance between each UWB transmitting and receiving unit and the terminal output from three UWB transmitting and receiving units or the distance between each UWB module and the terminal.
