Abstract: PURPOSE: A position recognition method of an automatic moving robot and device thereof are provided to obtain a current position of a robot by using silhouette information obtained from an image of a camera of the robot without a GPS(Global Positioning System), an odometer, and a radio wave transmitter in outdoor. CONSTITUTION: A position recognition method of an automatic moving robot comprises an image photographing unit(110), a silhouette information extraction unit(120), a road sign recognition unit(130), a silhouette information comparison and detection unit(140), a road sign position unit(150), and an integrated position recognition unit(160). A silhouette information extraction unit extracts silhouette information from images obtained through the image photographing unit. The road sign recognition unit extracts a road sign from the recorded image. The silhouette information comparison and detection unit obtains position information with respect to the recognized road sign by using the extracted silhouette information. The integrated position recognition unit decides an actual position of a vehicle through circulating a relative distance between the road signal and automatic driving robot by using the position information with respect to the surface sign.
