Abstract: In order to accurate the positioning of conveyor belt internal wire rope damage, a joint recognition algorithm based on corner feature vectors was proposed. Reference point for the joint, the joint image intact was selected According to the normalized product correlation algorithm, the Haar wavelet response distribution was calculated by using the Harris corner points as feature points, each joint was identified according to the feature vector matching of joint image. Experiments show that, this algorithm not only has good illumination robustness and recognition rate, but also has high speed and high efficiency, which can effectively solve the joint identification and fault location.
