Abstract:
A method and an apparatus for searching and following a target by using stereo vision is provided to detect objects close to a service robot, to present accurate shape of a target with image processing processed by a hardware chip, to reach the target without being collided with other objects by using collected information on surroundings, and to reach the target in a stable manner by matching information collected by stereo vision with original image processing. A method of searching and following a target for an intelligent home service robot includes a step(S110) of collecting commands issued externally; a step(S120) of processing visions for taking images through more than one camera, extracting a distance by calculating a disparity map about objects in the images taken by cameras, and extracting horizontal and vertical sizes on the objects with the extracted distance to sort out a target from objects; and a step(S160) of moving toward a target based on the result of processing visions.
Abstract:
An apparatus and a method for efficient image information transmission of an intelligent service robot system through using stereo vision processing are provided to transmit information, collected by a robot, to a server party for processing the collected information in consideration of loads of a network. A vision processor(100) collects videos photographed through cameras. With respect to the collected videos, the vision processor performs video processing for minimizing the amount of information about regions except an active region necessary for video processing in a robot server(20) for processing data transmitted from a robot terminal in a ubiquitous robot system. A communication unit(300) performs communication with the robot server, transmits the video information processed by the vision processor to the robot server and receives the processed result information from the robot server. A controller(200) controls the video processing by the vision processor, transmission of the processed video and operations of the robot terminal corresponding to the result information received from the robot server.
Abstract:
An apparatus for moving the center of gravity of a robot, and a system and a method using a same are provided to expand the moving range of the robot by allowing a caster to simply and easily get over an obstacle. An apparatus for moving the center of gravity of a robot includes a moving mass(440) and a mass moving device(400). The moving mass is installed inside a main body of the robot and has predetermined weight. The mass moving device moves the center of gravity of the robot by moving the moving mass in a specific direction. The mass moving device includes a moving motor(410), a timing pulley(420), and a timing belt(430). The moving motor rotates according to a control command. The timing pulley is connected to a rotary shaft of the moving motor and rotates to deliver a force. The timing belt changes a rotation force of the timing pulley to a linear movement for moving the moving mass. The mass moving device further includes a guide rail(450) helping to move the moving mass in a specific track.
Abstract:
PURPOSE: A method for controlling a power source of a display device using a frontal face detection apparatus and an apparatus thereof are provided to manage the power source of the device, by grasping device usage intention of a user intellectually. CONSTITUTION: A face detection part (100) judges a face of a user existing in the front, and a power source checking part checks power source state of the display device. A power source control part (400) controls the power source of the display device, by using the repetitive result of face detection according to the power source state and the existence of the face. The face detection part includes a frontal face checking part (110) checking whether the face is a frontal face or not. A repetitive variable management part (300) manages repetitive variables defining time or frequency of performing the face detection repetitively. [Reference numerals] (100) Face detection part; (110) Frontal face checking part; (200) Display power checking part (displaydevice_sw); (300) Repetitive variable management part (time_remain); (400) Power source control part
Abstract:
PURPOSE: An image based hand detecting apparatus and method thereof are provided to accurately detect a hand in the dark by creating a comparing result. CONSTITUTION: A hand image detecting unit(50) detects the hand image of a hand shape from an input image. A feature point extraction unit(60) extracts a feature point from the detected hand shape. An image rotation unit(70) rotates the detected hand shape or the stored hand images. A matching unit(80) compares the detected hand image with the stored hand image. When a hand image matched with the detected hand image is existed, a hand shape recognition unit(90) selects the hand image as the matched hand image.
Abstract:
PURPOSE: A camera image evaluation and correction method for stereo matching and a stereo camera system using the same are provided to offer right/left images for stereo matching which is properly controlled on the basis of the human. CONSTITUTION: A right and left motion vector separator(360) separates right and left motion vectors. A human detector(370) creates a left ROI(Region Of Interest) area and a right ROI area in a left image motion vector and a right image motion vector. An ROI representative value extractor(380) extracts a representative value in the left ROI image of the left ROI area and the right ROI image of the right ROI area.
