Railroad tunnel linings may have voids filled with water or air, or areas that lack compaction due to construction processes. These structural defects are hard to detect and require regular inspections to ensure safety. Existing convolutional neural network (CNN)-based inspection systems that employ ground-penetrating radar (GPR) imagery sometimes cannot fully assess the defects and ensure the str...Show More
Regular tunnel lining internal damage (TLID) inspection is very crucial for the railroad operation safety. However, traditional manual identification methods using ground penetrating radar (GPR) images suffer from limited accuracy and efficiency. Fortunately, CNN-based automatic inspection methods have the potential to replace manual inspections, offering improved precision and productivity. In th...Show More
Aiming at the problems of low efficiency and poor real-time performance in the printed circuit board (PCB) defect detection, a PCB defect detection method based on the improved YOLOv5 is proposed, which integrates the module of multiscale detection, attention mechanism and multi-branch. A shallow detection layer is added to detect smaller defect targets and fused with features of the deep network....Show More
