This paper focuses on a wire-tracking for all component wires in a highly bent electric cable, which is necessary for discussing the characteristics of cable products in actual use cases. Unique pre-processing for U-Net segmentation have been developed for this task. The pre-processing corresponds to the coordinate transformation process which converts bent cables to virtual straight cables and enables us to analyze highly bent electric cables using the conventional wire-tracking process for straight cables. By combining this pre-processing and U-Net, it becomes possible to detect shapes of all component wires in highly bent electric cables. The information of these wire shapes greatly enhances our understanding of the phenomena related to cable bending and our design process of cable products with better bending properties.
