Fault recognition accuracy in the trouble of moving EMU detection system (TEDS) is suboptimal. Thus, a method for locating potential fault areas at the bottom of EMU by means of weak texture matching is proposed. First, a large number of feature points in the weak texture areas are detected using the topological crossover number. Second, feature points are selected on the basis of the topological crossover number of each pixel within a specified ring area centered on the feature points. This approach aims to construct corresponding feature vectors to achieve the matching of weak texture features. Finally, the registered image is compared to locate the potential fault areas. Experimental results show that the algorithm ensures matching accuracy; it can also detect most potential fault areas. The matching accuracy of weak texture areas is more than 80%, with feature matching pairs in all image pairs. Such a result provides favorable conditions for accurate fault classification in the future.
