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.
Abstract:
PURPOSE: A method and an apparatus for real-time face detection using a stereo vision are provided to perform face detection in foreground including face pattern from whole video by stereo vision processor thereby widely reducing face detection processing time. CONSTITUTION: A vision processing unit(320) calculates distance information by usage of a plurality of images including face pattern. Based on the distance information, the vision processing unit divides foreground image including the face pattern and background image not including the face pattern. According to distance information, a face detection unit(330) adjusts video size of the foreground image. The face detection unit detects the face pattern from adjusted foreground image.
