AI Technical Summary
Existing object recognition technologies struggle to detect objects with smaller pixel counts in images, particularly in high-resolution images, due to computational constraints and the need for region-of-interest (ROI) selection, which can lead to incomplete processing and reduced detection precision.
An obstacle detection system that sets specific Regions Of Interest (ROIs) based on the track width and a predetermined ROI coefficient, determining appropriate ROI sizes and coordinates to balance detection precision, range, and computational costs, using a camera attached to a moving vehicle to monitor the structure gauge around the track.
Enables fast and highly precise detection of obstacles, ensuring comprehensive coverage of the structure gauge region while optimizing computational resources, thereby enhancing motorman-less operation safety in railway systems.
