Study for Catenary Fault Detection Based on MNP Method

Article Preview

Abstract:

For catenary faults are caused by hot, so infrared thermal imaging technology and image processing are combined in catenary thermal fault detection. In image process, image template matching can be used in target detection of infrared image. As mutual information is similarity measure criterion in image template matching, and weakness of NP window is long computing time, so the paper employ MNP method to instead the original NP window. Experimental results show calculating the joint probability distribution and the matching time of MNP method has advantages. When the template size is 5×5, MNP method has the higher template matching accuracy.
