Abstract Loosening detection; cascade deep convolutional neural network; object localization; saliency detection problem of
bolts on axlebox covers. Firstly, an SSD network based on ResNet50 and CBAM module by improving bolt image
features is proposed for locating bolts on axlebox covers. And then, the A2-PFN is proposed according to the slender
features of the marker lines for extracting more accurate marker lines regions of the bolts. Finally, a rectangular
approximation method is proposed to regularize the marker line regions as a way to calculate the angle of the marker
line and plot all the angle values into an angle table, according… More >
