Abstract:
PURPOSE: A device and a method for estimating a position of a movable body are provided to estimate a position of the movable body on a global map by matching the global map and a local map, thereby accurately estimating the position of the movable body. CONSTITUTION: A device for estimating a position of a movable body comprises a sensor information acquisition unit(100), a map standard storing unit(120), a global map generating unit(140), a local map generating unit(160), and a matching unit(180). The sensor information acquisition unit acquires moving distance information, distance measuring sensor information, image processing sensor information or GIS information. The map standard storing unit stores the information of properties and a position of obstacles in a space providing a travelling service with respect to the movable body. The global map generating unit generates the global map of the space base on the information acquired by the sensor information acquisition unit and the information of the properties and the position of the obstacles stored in the map standard storing unit. The local map generating unit generates a local map by receiving the ambient environment information from the sensor information acquisition unit when the movable body is in travelling. The matching unit estimates the position of the movable body on the global map by mating the local map and the global map.

Abstract:
PURPOSE: A position recognition method of an automatic moving robot and device thereof are provided to obtain a current position of a robot by using silhouette information obtained from an image of a camera of the robot without a GPS(Global Positioning System), an odometer, and a radio wave transmitter in outdoor. CONSTITUTION: A position recognition method of an automatic moving robot comprises an image photographing unit(110), a silhouette information extraction unit(120), a road sign recognition unit(130), a silhouette information comparison and detection unit(140), a road sign position unit(150), and an integrated position recognition unit(160). A silhouette information extraction unit extracts silhouette information from images obtained through the image photographing unit. The road sign recognition unit extracts a road sign from the recorded image. The silhouette information comparison and detection unit obtains position information with respect to the recognized road sign by using the extracted silhouette information. The integrated position recognition unit decides an actual position of a vehicle through circulating a relative distance between the road signal and automatic driving robot by using the position information with respect to the surface sign.

PURPOSE: A method and a device for controlling birds using a mobile robot are provided to prevent a collision between birds and an aircraft by exterminating the birds using a remote or free control mode. CONSTITUTION: A method for controlling birds using a mobile robot is as follows. Information about surrounding situations detected by a mobile robot is input. Birds are detected from the surrounding situation information(800). Bird control patterns, corresponding to the surrounding situation information, are extracted(810). A bird control task is allotted to the mobile robot(820). Processing information about the bird control task is received from the mobile robot and is analyzed(830).
Abstract:
PURPOSE: A multi image compression apparatus and a method thereof for compressing an image inputted from a camera are provided to accurately monitor network resource in order to support a data ratio compression mode. CONSTITUTION: A video input unit(301) acquires an image which a client desires to watch the image inputted from a camera and transfers the image to an image compression unit(402). An image compressing system(405) is embedded in a plurality of compressors. A controller(309) decides whether each compressor compresses the image in a JPEG2000 mode. A network interface unit(307) receives the compression mode information from a client.
Abstract:
A traffic control robot, a traffic control system and a traffic control method for using the same are provided to efficiently control The flow of the vehicles by using the traffic control robot in the position road in which the traffic control is required to the intersection and the railroad crossing etc. A traffic control robot(100) comprises a body(120), the mobile member(140), the robot controller, a sensor(150), a camera(160), a communication unit(170) and an auxiliary traffic sign(180). The robot arm for the hand signal is mounted on the body. The body performs the hand signal for the traffic control and guides the movement of vehicles and pedestrian. The mobile member is combined in the body for the movement in the road. The robot controller is operated with the already stored robot drive program. The robot controller controls the movement in the road by the mobile member and the performance of the hand signal by the robot arm. The sensor senses the obstacle. The camera takes a picture of surroundings. The communication unit communicates with the outside communication unit.
Abstract:
PURPOSE: A device and a method for extracting the product information using the pattern information are provided to extract the product information using the defined type of the product information by collecting a document including the product information from a web shopping mall and defining the information type of the collected document. CONSTITUTION: The device for extracting the product information comprises a catalog URL(Uniform Resource Locator) collector(13) collecting the catalog information from the Internet shopping mall(11), a pattern information collector(14) having an HTML(HyperText Markup Language) collector and extracting the pattern information of a product from the shopping mall, a product information extractor(15) extracting the product information from the shopping mall by using the collected pattern information, and a DB(12) including a shopping mall information DB(101), a pattern information DB(102) and a product information DB(103). The pattern information collector loads the shopping mall information and extracts and stores the type and pattern information of the product included to the web document in the pattern information DB.
