Rail Vision Ltd., a technology company in the early stages of commercialisation, has been granted a European patent for an innovative imaging system designed to improve railway safety by significantly increasing the sampling rate of detectors in a Selected Region of Interest (SROI).
The patented technology combines an imaging device with a processing unit that work together to capture, analyse, and prioritise visual data from a train’s forward-facing camera. The device collects multiple datasets from image frames across several operational cycles, while the processing unit identifies a specific region of interest. Partial datasets from this SROI are then acquired during residual time in the cycle, enabling higher sampling rates in areas deemed most critical for safety.
Mounted on a locomotive and facing the direction of travel, the processing unit incorporates a tracking module that detects the rails, defines margins on either side, calculates a safe braking line based on the train’s stopping distance, and establishes a safe zone. The SROI is positioned at the far end of this zone within the image frames, allowing for earlier detection of potential hazards and faster response.
“Securing this European patent is another strong validation of Rail Vision’s innovation,” said David BenDavid, CEO of Rail Vision. “By boosting the sampling rate, we’re enabling train operators to detect hazards sooner, react faster, and improve functional efficiency to operate more safely. This technology is another step toward our vision of making railway transportation safer, smarter, and more efficient worldwide.”
The grant strengthens Rail Vision’s patent portfolio in key markets, furthering its mission to enhance railway safety and operational efficiency on a global scale.
