DEVICE AND METHOD FOR RECOGNIZING LOCATION OF MOBILE ROBOT BY MEANS OF EDGE-BASED READJUSTMENT

摘要

Disclosed are a device and a method for recognizing location of a mobile robot by means of edge-based readjustment. A device for recognizing location of a mobile robot, according to the present invention, comprises: two wide-angle cameras for obtaining, with respect to the operation of a mobile robot, a pair of stereo images about a region of interest comprising vertical direction and horizontal direction; and a location recognition unit for extracting an edge from the obtained stereo images so as to project each seed inside key frames provided on the basis of the extracted edge and updating, in the direction of the increment of a cost which is calculated from the result of the projection, a state parameter that shows the rotation and movement of optical cameras so as to estimate the current location by means of the updated result.
