Apparatus and method for effectively transmitting image through stereo vision processing in intelligent service robot system
First Claim
1. A data transmission apparatus of an intelligent service robot system comprising:
- a vision processor for collecting images captured through a camera, and performing an image process on the collected image to minimize a quantity of information about unnecessary regions in the collected image, where the unnecessary regions are regions in the collected image that are unnecessary for performing an image process in a robot server that processes image data transmitted from a robot terminal in an ubiquitous robot system;
a communicating unit for communicating with the robot server, transmitting the processed image data from the vision processor to the robot server, and receiving corresponding result data from the robot server; and
a controller for controlling the image process and the transmission of the processed image data in the vision processor, and a corresponding operation of the robot terminal performed according to result data received from the robot server.

Abstract
A data transmission apparatus of an intelligent robot system and a method thereof are provided. The data transmission apparatus includes a vision processor collector, a communicating unit, and a controller. The vision processor collects images captured through a camera, and performs an image process on the collected image to minimize a quantity of information about unnecessary regions in the collected image. The communicating unit communicates with the robot server, transmits the processed image data from the vision processor to the robot server, and receives corresponding result data from the robot server. The controller controls the image process and the transmission of the processed image data in the vision processor, and a corresponding operation of the robot terminal performed according to result data received from the robot server.

7. A method of transmitting data in an intelligent service robot system comprising:
-
obtaining image data through left and right cameras of a stereo camera; extracting information about target objects included in the image data by performing a stereo vision process on the image data obtained through the left and right cameras; determining whether target objects to track are present in the stereo vision processed image data or not; setting objects corresponding to the target objects as an active region if the target objects are present in the stereo vision processed image data; matching a coordinate of a camera image with a result of stereo matching on the active region; changing image values of regions in the stereo vision processed image except the active region to meaningless data; and compressing entire image including the change image values and transmitting the compressed image to a robot server. - View Dependent Claims (8, 9, 10, 11)
