Abstract:
본 발명은 영상 전송 기술에 관한 것으로서, 더 상세하게는 분산된 영상 센서 노드들로 이루어진 무선 센서 네트워크 하에서 그들 사이의 효과적인 저지연/고화질 영상 전송을 위한 적응형 시스템 및 방법에 관한 것이다. 본 발명에 따르면, 무선 센서 네트워크의 상호 통신 프로토콜(inter-communication protocol)에서 각 노드는 적응적으로 저지연 및 고화질 성능을 달성할 수 있는 지연 방식(relaying scheme)을 선택하고 인트라 처리 프로토콜(intra-processing protocol)에서 저지연을 위한 영상 정보 처리를 함으로써 무선 센서 네트워크 환경에서 신속하고 정확한 영상 정보 전달이 요구될 때, 효과적으로 적용될 수 있다.
Abstract:
The present invention relates to an image transmission technology and, more particularly, to an adaptive system and method for effective low delay and high definition image transmission between distributed image sensor nodes in a wireless sensor network including the distributed image sensor nodes. According to the present invention, each of the nodes selects a relaying scheme that is capable of achieving a low delay and high definition performance in an adaptive manner in an inter-communication protocol of the wireless sensor network, and image information processing for low delay is performed in an intra-processing protocol, and thus effective application is possible when rapid and accurate image information transmission is required in a wireless sensor network environment. [Reference numerals] (AA) Start; (BB) End; (S900) Each node in a system acquires channel information on a link between the node and the subsequent node; (S910) Calculate an expected value of a channel capacity and an expected value of delay time based on the acquired channel information by each of three relay methods; (S920) Select a method by which the largest channel capacity is expected except a relay method by which the expected value of the delay time exceeds a limit value
Abstract:
PURPOSE: A system for producing a formation of a robot and a method thereof are provided to autonomously produce various formations based on dispersed intelligence and ad-hoc networking, and to improve an operation effect of the robot. CONSTITUTION: A system(10) for producing a formation of a robot comprises a control system(100), a seed robot, and a follower robot. The seed robot selects one or more robots responding to a call signal as the follower robot, and produces an arbitrary formation through interlocking with the follower robot. The follower robot is transferred to a formation position point coordinate included to the call signal transmitted from the seed robot. The formation starting command includes information about the arbitrary formation and parameter setup information related to the formation.

본 발명은 이동 표적의 탐지 기술에 관한 것으로서, 더 상세하게는 다수의 지상무인 차량 운용 환경에서 이동 표적의 진행방향을 예측 후 인접 무인차량에게 실시간 전파함으로써 표적 탐지 획득시간을 단축하고 임무 단절을 초래하는 상황을 미연에 예방할 수 있도록 하는 탐지 획득시간 단축 방법에 대한 것이다.
Abstract:
PURPOSE: An image processing device and a method thereof are provided to compare periodically repeated image frames and use the repeated image information in image processing. CONSTITUTION: A camera module(101) photographs an image about an interesting area while a camera periodically and repetitively moves along with a set moving path. An image processing unit(102) detects image frames which are periodically repeated based on the photographed images. The image processing unit eliminates image information which is repeated from the image frames which are periodically repeated.
