Detection of vibration damper based on combination features and cascade classifier

A vibration hammer detection algorithm for high-voltage transmission lines was proposed.The vibration hammer was detected based on the block Haar feature,the region-based LBP feature,and the HOG feature together.The detection procedures included five steps.The images to be detected were preprocessed.Template matching was implemented using an improved normalized cross-correlation matching algorithm to obtain a suspected regional sample set of the vibration damper.Combination features were extracted.Multi-level classification was implemented using cascaded classifiers.Statistical classification results were obtained.The practice shows that the algorithm has high precision,recall and accuracy.
