MOBILE ROBOT AND CONTROLLING METHOD OF THE SAME

PURPOSE: A moving robot and a control method thereof are provided to coordinate feature points regardless of change of light condition because the feature points are extracted from detected images and geometric constraint conditions are applied by tridimensional lines. CONSTITUTION: A moving robot comprises an image detecting unit(100), a straight line detecting unit(210), a feature line extracting unit(220), a feature point extracting unit(230), a control unit(300), and a storing unit(400). The image detecting unit takes photograph around a robot to detect at least one image. The straight line detecting unit extracts at least one straight line from the image. The feature line extracting unit extracts at least one feature line toward center of the image among the straight lines. The feature point extracting unit extracts at least one feature point from the image. The control unit coordinates the feature points and recognizes the location based on coordinated result of the feature points. The storing unit stores the image information such as the images, the feature lines, and the feature points.
