METHOD FOR EXTRACTING DISTANCE OF LANDMARK OF MOBILE ROBOT WITH A SINGLE CAMERA

摘要

A method for extracting a distance of a landmark of a mobile robot is provided to reduce loads of a main processor by avoiding use of an algorithm for processing a signal. A method for extracting a distance of a landmark of a mobile robot, includes a step of calculating the horizontal distance(D1) between the point where the landmark is projected into an image plane of a camera of the mobile robot to the perpendicular bisector of the image plane, a step of moving the robot along a focal axis of the camera from the position to a target point, and photographing the landmark, a step of calculating the horizontal distance(D2) between the point where the landmark photographed at the target point is projected into an image plane of the camera to the perpendicular bisector of the image plane, and a step of calculating the distance(D) between the camera of the robot at the target point to the point where the focal axis of the camera and the plane including the landmark form a perpendicularity by using the distances(D1,D2).
