APPARATUS FOR RECOGNIZING LOCATION MOBILE ROBOT USING KEY POINT BASED ON GRADIENT AND METHOD THEREOF

摘要

An apparatus and method for recognizing a position of a mobile robot using gradient-based feature points according to the present invention are disclosed. The apparatus for recognizing the position of the mobile robot according to the present invention includes two wide angle cameras for acquiring a pair of stereo images for a region of interest including a vertical direction and a horizontal direction as the mobile robot operates; And acquiring a gradient in the x-axis direction and the y-axis direction in each pixel of the acquired stereo image, extracting an edge based on the gradient in the x-axis direction and the y-axis direction obtained, And a position recognition unit for estimating the position.
