Abstract:
1. An apparatus for recognizing a position of a mobile robot, the apparatus comprising: an infrared lighting unit irradiating an infrared ray to a landmark form of a plurality of marks reflecting the infrared ray and attached to a predetermined space; an infrared camera installed in the mobile robot and photographing the landmark and obtaining a binary image; a 2-axis inclinometer installed in the mobile robot and detecting inclination information of the mobile robot; a mark detector labeling a partial image included in the binary image and detecting the mark by using a number and/or dispersion of labeled pixels for each the partial image; and a position detector detecting coordinates and an azimuth of the mobile robot by using centric coordinates of the detected mark and the inclination in formation of the mobile robot, wherein the apparatus has an inclination correction function.
