Research on Detection of Bird Nests in Overhead Catenary Based on Deep Convolutional Neural Network
Nesting on railway catenaries by birds has been an important cause of catenary failure. At present, the inspection for judging the existence of bird’s nests is carried out artificially, which has much shortcomings in heavy working intensity, high missing-inspection rate and low detecting efficiency. So improving detecting efficiency and then removing potential hazards in time is significant to ensure the security operation of railway vehicles. Aiming at such shortcomings, a Faster R-CNN model based on deep convolution neural network was proposed to identify bird’s nests on catenaries automatically. After the steps of customizing appropriate network structure and parameters and going on pre-training, RPN network training, Fast R-CNN network training and the joint training of RPN network and Fast R-CNN network, a Faster R-CNN model which could be implemented bird’s nests detection was established. Experiment has proved that the recognizing accuracy of Faster R-CNN model is 88.5% and the recognizing time of a picture is 79 ms. Compared with the traditional HOG, DPM and convolutional neural network method, it was verify that the Faster R-CNN model based on deep convolutional neural network was efficient on detecting the existence of bird’s nests on railway catenaries.
