Abstract

An elevator-rope inspection device comprising a camera for capturing images of the elevator rope R, and an image-processing unit for processing a captured image outputted by the camera, wherein the image-processing unit detects a location of wear by implementing binarization on the captured images, and a labeling process that assigns a label to the location of wear, measures a distance between labels, andassigned by the labeling process, and when that distance is less than a fixed value, it judges that the area between labels is a wire break, so texture information of the elevator rope is unnecessary in advance.
