Abstract
DMI can reflect the operation status of on-board ATP of the train control system in real time, and the recognition of its display content is an important prerequisite for realizing the automatic test of on-board ATP. The existing identification DMI technology has incomplete identification types and low detection speed. In order to achieve a better detection effect and a certain degree of wide applicability, a DMI information recognition method based on the YOLOv8 instance segmentation model is proposed. This method improves the segmentation and classification accuracy of DMI interface information by improving the training strategy of the instance segmentation task, completes the extraction of text information by combining OCR technology, and achieves high-precision segmentation of the most restrictive speed profile by combining the Douglas-Peucker algorithm. The experimental results show that the method proposed in this paper can accurately extract all the useful information of the DMI interface, meet the needs of laboratory testing, and lay the foundation for automatic testing.
