A cable maintenance robot system in smart buildings

Abstract

The present invention discloses a cable maintenance robot system in a smart building, which belongs to the technical field of cable surface defect detection. The present invention can more accurately characterize the degree of cable cracking by the total length of all retained contour lines in the RGB images of the cables on both sides, and more accurately characterize the degree of cable bulging by screening the mutation pixel points and using the total number of all mutation pixel points in the depth images of the cables on both sides. The present invention also uses the average of the y-axis coordinate differences yc1 and yc2 between the y-axis minimum value point and the y-axis maximum value point on the center line of the cable area on both sides as the cable distortion parameter, which can more accurately characterize the cable distortion degree of the current section, thereby obtaining accurate cracking degree scores, bulging degree scores and distortion degree scores, and finally accurately evaluating the cable status of the current section through the above three scores.
